75

Testing an Application (1)

Run on Server or Web App Preview – run on server is better, because it has a fixed port instead of a random one-time port used by Web App Preview. For testing purposes during class, you can select Web App Preview – note the port issue if you change to Google or FireFox

© 2014 SAP AG. All rights reserved.

76

Testing an Application (2)

© 2014 SAP AG. All rights reserved.

77

Web Application Preview – Jetty Disadvantages compared to testing on server:





Based on Internet Explorer, therefore does not display most CSS3 features.



Creates a random port which stops working when Web App View is closed, if link is copied into a browser for debugging, this link stops working as well.



Therefore, this is not recommended.

Programming Applications

SAPUI5 Bootstrap



UI5 pages always have to start with the bootstrap, to load the UI5 runtime



Attributes of the script tag are evaluated and used to configure the runtime: o data-sap-ui-libs: the controls libraries to be used, comma-separated. o data-sap-ui-theme: the theme o There are more attributes: data-sap-ui-language, data-sap-ui-rtl, … o Instead of putting the attributes in the script tag, many can also be added as URL parameters

© 2014 SAP AG. All rights reserved.

83

Runtime Behavior of Bootstrap



jQuery enrichment with plugins – namespace jQuery.sap



Creation global object sap



SAPUI5 core class and all dependencies are executed



Runtime configuration is determined



All libraries and modules declared in the config. and their dependencies are loaded



Stylesheet for the config. themes of each loaded libs are added to the page



Loading of libs is finished and document ready state  initEvent of Core fired  all registered eventhandlers are executed

© 2014 SAP AG. All rights reserved.

84

Configuration of the UI5 Runtime



Individual configuration data-sap-ui-attribute



data: to comply with W3C recommendation for custom attriubtes



sap-ui: identifier for SAPUI5 attributes



attribute: an specific configuration attribute



Access configuration: sap.ui.getCore().getConfiguration();  sap.ui.core.Configuration

Internals about UI5 Rendering

UI5 control tree(s) are only rendered when the HTML page is finished loading  Only then the UI areas do actually exist in the browser’s DOM  This corresponds with jQuery’s $(document).ready() function

UI5 largely uses HTML strings to render its controls  Historically using innerHTML for changing HTML was much faster than changing the DOM for the same purpose.

Changes to controls (add/remove properties) are not directly carried out    

Onload at initialization (placeAt calls are buffered until then) After control event handlers have finished their work After application logic has finished changing controls (UI5 registers a timeout) When core method applyChanges() is triggered

© 2014 SAP AG. All rights reserved.

88

Application Script and UI Area •

After the bootstrap script tag an "application script" can follow in which the UI5 application is written: – You create your controls like layouts and TextFields – Display your controls in an HTML element called "UI area" by invoking the placeAt method (there can be multiple UI areas)

1. Bootstrap 2. Application 3. UI-Area

© 2014 SAP AG. All rights reserved.

89

Useful Core Functions sap.ui.getCore()

jQuery.sap.domById(id)

 Gets any HTML element with id id  If there is also a UI5 control with id id, the sap.ui.getCore().byId(id) element returned is the topmost HTML element of this UI5 control (the UI5 control  Gets an instance of a UI5 control which was id is always used there) created with id id  Similar to document.getElementById but  Can be used to access removed controls gets rid of IE bug which also retrieves (even though the id doesn’t exist in the elements with the name of id DOM anymore)  Gets a core instance

sap.ui.getCore().applyChanges()

jQuery.sap.byId(id)

 Carries out and renders the changes for UI5  Returns the jQuery object of the DOM controls immediately, before the runtime element with the specified id would do it (use carefully!!)  Similar to jQuery(„#myId“) or $(„#myId“) but handles escaping of dots and adds the hash character

MVC

Basic Model-View-Controller Concept



Views can be defined using o XML with HTML, mixed or standalone (sap.ui.core.mvc.XMLView) o JavaScript (sap.ui.core.mvc.JSView) o JSON (sap.ui.core.mvc.JSONView) o declarative HTML (sap.ui.core.mvc.HTMLView)



Controller o bound to a view or standalone o can also be used by multiple views



Model: Data binding can be used on the views

© 2014 SAP AG. All rights reserved.

114

File Location Logic



Controllers and views use the require/declare logic, so if a controller is referenced like this:



UI5 then checks if you already have defined the controller like this in one of your already processed application sources



If this is not the case then UI5 tries to load this definition from a file that by default is located in your UI5 resources folder. This applies to views as well. resources/sap/hcm/Address.controller.js © 2014 SAP AG. All rights reserved.

115

registerModulePath •

UI5 by default will try to load any required modules from its resource root URL, namely from the centrally deployed web application. This would fail for the modules contained in your web application.



Mixed location scenarios are supported with jQuery.sap.registerModulePath



Example of using registerModulePath:

© 2014 SAP AG. All rights reserved.

116

Controller Events

Currently there are 4 events defined in a controller:  onInit





You can add handlers for any of these for to your controller class:

– Fired when the view is first instantiated

 onBeforeRendering – Fired before the view is rendered

 onAfterRendering – Fired when the view has been rendered (the HTML is injected into the document)

 onExit – Fired when the controller is destroyed – Can be used to free resources

Databinding

UI5 Data Binding In UI5, DATA BINDING is used to bind UI5 controls to a data source that holds the application data, so that the controls are updated automatically whenever the application data is changed.





With TWO-WAY-BINDING the application data is updated whenever the value of a bound control changes, e.g. through user input.

132

Data Binding: Model Types UI5 data binding supports three different model implementations:

JSON model  supports data in a JavaScript Object Notation format  supports two-way binding

XML model  supports XML data  supports two-way binding

OData model  supports OData compliant data  creates OData requests and handles responses  includes the open source library dataJS to handle OData requests and data  experimental two-way binding



Additionally, the ResourceModel helps binding translated texts



Applications can create their own Model implementations © 2014 SAP AG. All rights reserved.

133

Creating a Model Instance



To use data binding in a SAPUI5 applications you will need to instantiate the appropiate model first. The constructor takes the URL of the model data or the data itself as the first parameter.

JSON-Model:

XML-Model:

OData-Model:

© 2014 SAP AG. All rights reserved.

134

Assigning the Model



After the model has been created you can assign the model to the Core or specific controls with the setModel method



The relevant model for a control is the one which is nearest to it on the path up to the root (UI area) o If there is no model in the root path found the one attached to the core becomes the relevant model

© 2014 SAP AG. All rights reserved.

135

Property Binding •

Most of the properties of a control can be bound to model properties



There are two ways to bind properties to the model, in the constructor with curly braces or using the bindProperty method

bindProperty method: • oControl.bindProperty("controlProperty", "modelProperty");

curly braces syntax: var oControl = new sap.ui.commons.TextView({ controlProperty: "{modelProperty}" });

(alternatively) by path: var oControl = new sap.ui.commons.TextView({ controlProperty: { path: “modelProperty” } }); © 2014 SAP AG. All rights reserved.

Absolute binding paths within this model: /company/name /company/info/employees /company/contacts (a collection!) /company/contacts/0/name



Relative binding paths within the "/company" context: name info/employees contacts



Relative binding paths within an aggregation binding of "/company/contacts": name phone 140

Aggregation Binding



Aggregation binding is used to bind a collection of values, like binding multiple rows to a table. To use aggregation you will have to use a control that acts as a template.



The aggregation binding can also be defined using the bindAggregation method of a control.

145

Extended Data Binding Syntax



Instead of only using the token name of a model property, can also use the extended data binding syntax o This enables you to use formatters and the type system for property binding and templates, filter and sorters for aggregation binding



To use the extended syntax, you supply an object literal for the bound property/aggregation.

Formatters

Exercise 8



For properties you can supply a formatter function which will be called with the value of the model property.



The return value of the formatter function is used as the value of the bound control:

Type System



Data binding supports the definition of types which can be handed over when binding properties o



Bound properties with a defined type will automatically be formatted when displayed in the UI, input values in UI controls are parsed and converted back to the defined type in the model.

For each Type you can define the following parameters in the constructor: o format options: Format options define how a value is formatted and displayed in the UI. o constraints (optional): Constraints define how an input value entered in the UI should look like. When parsing the value will be validated against these constraints.

Calculated Fields •

Calculated Fields allow the binding of multiple properties in different models to a single property of a control. o E.g. - value property of text field may be bound to a property firstName and a property lastName in a model.



Application can access these values in a formatter function and decide how they will be processed or combined together:

Calculated Fields – Extended Syntax •

The extended syntax for calculated fields can be used in declarative views such as html and xml views



Because it is still experimental, it needs to be switched on via the configuration flag xx-bindingSyntax=„complex“ within the bootstrap

Adding OData Query Options •

SAPUI5 handles most of the URL parameters for OData services automatically. You do have the ability to add query options manually; either by adding them to service URL or passing a map of parameters when using bindElement or bindAggregation. Expand Parameter:

Select Parameter:

oControl.bindElement( "/Category(1)", { expand: "Products" } );

oControl.bindElement( "/Category(1)", { expand: "Products", select: "Name,ID,Products" });

oTable.bindRows({ path: "/Products", parameters: { expand: "Category" } });

Resource Handling

Overview Resource Handling •

The Resource Handling of SAPUI5 is separated in two parts:

Client-side Mechanisms • Modularization ► Require/Declare for JavaScript files • Localization ► Resource Bundles Both concepts are loading additional resources from a server where this server might be any kind of web server (simple, Java, ABAP …), independent of the server side technology.

Server-side Mechanisms •





SAPUI5 provides a Resource Handler for the Java server and the integration into the Eclipse IDE, aligned with the concept of the JavaServer Faces - Resource Handler, also supporting standard and test-relevant resources Additional features: ► Theme fallback ► Resource Bundle fallback SAPUI5 also provides a Resource Handler for the ABAP server which is used for SAPUI5 applications to serve the resources from the UI libraries properly.

• Both parts are not dependent on each other. Furthermore they are complementary. © 2014 SAP AG. All rights reserved.

All rights reserved.

186

Modularization

Modularization using require •

The UI5 framework has built in support for modularizing larger JavaScript applications. o Instead of defining (and loading) one large chunk of JavaScript code, an application can be split into smaller parts, which then can be loaded at runtime when they are needed. These smaller, individual files are called Modules in UI5. o To load a module, the function jQuery.sap.require must be used. o In a module name all “.” are replaced by “/” and an “.js” extension is added to create a path. So sap.ui.commons.MessageBox will become sap/ui/commons/MessageBox.js



This is an example: jQuery.sap.require("sap.ui.commons.MessageBox"); function onPressButton() { sap.ui.commons.MessageBox.alert("Hello World!"); } © 2014 SAP AG. All rights reserved.

188

Modularization using declare •

In order to create your own JavaScript Module you need to “declare” the module: o A file becomes a module by calling the jQuery.sap.declare function. This tells the UI5 runtime about the name of the module. UI5 runtime keeps track which modules are already loaded. o If a module is required (jQuery.sap.require) and it hasn’t been loaded before, it is loaded automatically. While it is carried out, it calls the declare method, so from now on UI5 knows that it has been loaded and when the next require comes about nothing needs to be done anymore. o The declare function checks if the parent namespace object exists and if not, creates it. // declaration of the module. Will ensure that the namespace 'my.useful' exists. jQuery.sap.declare("my.useful.SampleModule"); // list of dependencies of this module jQuery.sap.require("sap.ui.core.Core"); jQuery.sap.require("some.other.Module"); jQuery.sap.require("you.can.Also", "list.multiple.Modules", "if.you.Want"); // create the 'main' object of the module my.useful.SampleModule = {};

© 2014 SAP AG. All rights reserved.

189

registerModulePath •

UI5 by default will try to load any required modules from its resource root URL, namely from the centrally deployed web application. This would fail for the modules contained in your web application.



Mixed location scenarios are supported with jQuery.sap.registerModulePath



Example of using registerModulePath:

Localization

Localization / Resource Bundle •

Exercise 14

UI5 has a built-in localization concept, which is aligned to the ResourceBundle concept in Java. o

You can get the URL for a resource with this:

var sUrl = sap.ui.resource("sap.ui.table","messagebundle.properties");



Get the resource bundle for a given language (if no locale is given, English is loaded by default): jQuery.sap.require("jquery.sap.resources"); var oBundle = jQuery.sap.resources({url : sUrl, locale: sLocale});



And then access the texts in the resource bundle: var sText = oBundle.getText(sKey);

Localization with Resource Model

Exercise 15



With the ResourceModel, there is a wrapper for resource bundles that exposes the localized texts as a model for data binding.



A ResourceModel can be instantiated with a bundleName or a bundleUrl which points to a resource bundle. When using the bundle name the file must have the .properties suffix.



Example: var oModel = new sap.ui.model.resource.ResourceModel({ bundleUrl: "myBundle.properties", // will use myBundle_en.properties bundleLocale: "en“ // optional, default is current language, so better omit it }); var oControl = new sap.ui.commons.Button({ id : "myButton", text : "{i18n>MY_BUTTON_TEXT}“ // this points to a named model }); // attach the resource model with the symbolic name "i18n"

Notepad Controls

What is a Control?



An object that defines the appearance and behavior of a screen area.



Typically has properties like "text" or "width" that modify the appearance or relate to the data displayed by the Control.



It can aggregate other Controls: o This means it is a sort of container or layout Control when the application can add the child controls to use – or a composite Control if the Control itself decides what the child Controls are and just re-uses these available components.



It can also have associated Controls that are not part or children of this Control, but rather loosely related.



A Control can fire well-defined events. o Typically, these have a meaning that relates to the Control's purpose and functionality and is on a semantically higher level than "click" or other browser events. Examples would be triggerSearch in a SearchField or collapse in a Panel. © 2014 SAP AG. All rights reserved.

201

UI5 Controls Overview



There are two approaches to develop UI5 Controls, either with tool support, or just as part of a plain JS file.



This section deals with creating custom controls in JavaScript with the extend method.



Since an IDE is not needed to create new controls with the extend method these controls have been named "Notepad Controls".



Technically, this functionality is not restricted to Controls.



Arbitrary objects derived from sap.ui.base.Object can be created or extended.

© 2014 SAP AG. All rights reserved.

202

The extend Method •

The extend() method is available on all Controls (and the base classes) and is used to define a new subclass.



Creating a new control: sap.ui.core.Control.extend(sName, oDefinition);



Creating a new Control which inherits from Button: sap.ui.commons.Button.extend(sName, oDefinition);



The parameters to this function are the name and the definition of the new control type. o The definition part contains information about the control API, which properties, aggregations, events, etc. the control has and the implementation of the control methods.



Some methods such as the getters and setters for the properties and aggregations or the methods for attaching/detaching event handlers are automatically created by UI5. © 2014 SAP AG. All rights reserved.

203

Control Definition



The definition object for a custom control may contain metadata, public and private methods, event handler and the renderer:

© 2014 SAP AG. All rights reserved.

204

Basic Example

© 2014 SAP AG. All rights reserved.

205

Control Metadata



The metadata in the control definition consists of objects for the control properties, events and aggregations. Properties

Example

type: The data type of the Control property.

properties: { title: "string", btnTxt: { defaultValue: "Search"}, showLogoutButton: { type: "boolean", defaultValue: true }, width: { type: "sap.ui.core.CSSSize", defaultValue: "50px" } }

• • • •

string for a string property (default) int or float for number properties int[] for an array of integers, string[] for an array of strings, etc. sap.ui.core.CSSSize for a customdefined type

defaultValue: The default value of the property. (undefined if not set)

© 2014 SAP AG. All rights reserved.

206

Control Metadata Events

Aggregations

Events are specified by the event name only. In many cases there is nothing to configure about them, so just give an empty object.

Aggregations and associations are defined by their name, along with an object that can have a type, a multiple flag and a singularName.

Controls can enable events to be interrupted by the application, using the enablePreventDefault flag.

aggregations: { acceptButton: "sap.ui.commons.Button", worksetItems: { type: "sap.ui.ux3.NavigationItem", multiple: true, singularName : "worksetItem" } }

events: { logout: {}, close: { enablePreventDefault : true } }

© 2014 SAP AG. All rights reserved.

207

Control Methods •

After the metadata is defined, you can add any method implementations to your new Control. The method names can be chosen freely, some method names must be avoided though: o o o



Names of methods that are provided by a super class. Methods starting with set, get, insert, add, remove or indexOf may collide with setters/getters for properties or aggregations you defined. Methods starting with attach, detach or fire may collide with methods created for events.

There are some method names you may use but which have a special meaning: o on...: Methods starting with "on" are event handlers that are automatically bound to browser events. o init: Is the name of the initialization function called right after Control instantiation. o renderer: The name of the function that creates the HTML for the control.

© 2014 SAP AG. All rights reserved.

208

Control Methods •

Public / private methods o The convention is that private methods start with an underscore. All other methods are considered public.



init Method o The init() method is invoked by the UI5 core for each control instance right after the constructor. Use this to set up things like internal variables or sub-controls of a composite. This method is considered private and only to be called by the UI5 core.



onAfterRendering Method o The onAfterRendering() method is invoked after the controller's View is re-rendered.



Event handler methods o Methods that have a name starting with on are reserved for event handlers. For common events such as click or keydown, browser event handlers for these methods are registered automatically by the UI5 core.

© 2014 SAP AG. All rights reserved.

209

Control Methods – Examples

// public method divide: function(x, y) { if (this._checkForZero(y)) { throw new Error("Second parameter may not be zero"); } return x / y; }, // private method _checkForZero: function(y) { if (y === 0) { return true; } return false; },

© 2014 SAP AG. All rights reserved.

// init method, invoked when control // is instantiated init: function() { this._bSearchTriggered = false; this._oSearchBtn = new sap.ui.commons.Button( this.getId() + "-searchBtn", { text: "Search" } ); }, // event handler onclick: function(e) { alert("Control " + this.getId() + " was clicked."); }

210

Control Renderer Example: •

The renderer method is responsible for creating the HTML structure that makes up the control. It is different from the other methods, as it is a static one, so the this keyword is not available. Instead, a control instance and a RenderManager instance are given to the method.

• If an existing renderer should be used without modification, you can give the name of this renderer class. © 2014 SAP AG. All rights reserved.

renderer: function(oRm, oCtrl) { oRm.write(""); oRm.writeEscaped(oCtrl.getText()); oRm.write(""); }

Using an existing renderer: renderer: "sap.ui.commons.ButtonRenderer"

211

Control Renderer (Additional Information)

• The newly created renderer type will inherit from the renderer of the parent Control. • So if your new Control extends TextField, the given function will be added to a class that inherits from sap.ui.commons.TextFieldRenderer (and will have access to that one's other functions). • However, your renderer method will override the parent renderer method, so no HTML will be written as long as your method is not taking care of it. • If an existing renderer should be used without modification, you can give the name of this renderer class: • renderer: "sap.ui.commons.ButtonRenderer" •

However, a normal Control Renderer can also override or implement methods from its Renderer superclass



Or just separate out some helper functions. continued © 2014 SAP AG. All rights reserved.

212

Control Renderer (Additional Information)



This is possible as well here, but in this case these methods need to be packed together into an object, so the extend method knows they should all go into the Control Renderer.



The main rendering method is called "render" - just like in a normal Control Renderer.



The keyword "this" actually refers to the Control Renderer type here, so it is used to access the other methods:

renderer: { render: function(rm, oControl) { rm.write(""); rm.writeEscaped(this.square(oControl.getValue())); rm.write(""); }, square: function(value) { return value * value; } }

© 2014 SAP AG. All rights reserved.

213

Writing a Control Renderer Class



Extract the implementation from the control to a separat rendering class: Method

Description

write()

Writes HTML output

writeControlData()

Writes ID and recognition data of control to HTML

renderControl()

Converts the specific control into HTML and adds the output to the HTML. This is used to render child components

214

Renderer Class Implementation jQuery.sap.declare(„com.sap.ui.HelloControlRenderer"); com.sap.ui.HelloControlRenderer = { }; com.sap.ui.HelloControlRenderer.render = function(oRm, oControl) { oRm.write("Hello "); // write the Control property 'name', with XSS protection oRm.writeEscaped(oControl.getName()); oRm.write(""); };

Components

Components Overview •

UI5 components are independent and reusable parts of the UI5 Application that may be developed by different development teams in different projects.



A UI5 component consists of a folder that has a name of the component and that at least contains two files: o o



Component.js - the Component Controller that also includes the metadata for runtime component.json - Component descriptor that contains the metadata for design time

There are two types of components: o

a UIComponent has a UI part (examples: custom button or a form)

 Base class for all UI Components: sap.ui.core.UIComponent o

a Faceless Component does not (examples: data transfer helper)

 Base class for all Faceless Components: sap.ui.core.Component



Components can either inherit from their base classes or from other component in order to inherit and extend its functionality.

© 2014 SAP AG. All rights reserved.

225

Creating a New Component – Component.js 1. Define an new (UI)Component: jQuery.sap.require("sap.ui.core.UIComponent"); jQuery.sap.require("sap.ui.commons.Button"); jQuery.sap.declare("samples.components.button.Component");

2. Set the metadata (properties, aggregations, events of the new component): sap.ui.core.UIComponent.extend("samples.components.button.Component", { metadata : { properties : { text: "string" } }});

3. Set the methods the component should have: samples.components.button.Component.prototype.createContent = function(){ this.oButton = new sap.ui.commons.Button("btn"); return this.oButton; };

© 2014 SAP AG. All rights reserved.

226

Creating a New Component – component.json  The component.json file is needed for design time environments so they know the specifics of the component.  The file is not loaded during the runtime of an application and thus not needed there. {

}

"name": "samples.components.button", "version": "0.1.0", "description": "Sample button components", "keywords": [ "button", "example" ], "dependencies": { }

© 2014 SAP AG. All rights reserved.

227

Using the New Component  Once the Component is defined as above, it can be used right away, just like any other UI5 Component. var oComponent = sap.ui.getCore().createComponent({ name: "samples.components.button", id: "Comp", settings: {text: "Hello World"} }); var oComponentCont = new sap.ui.core.ComponentContainer("CompCont", { component: oComponent }); oCompCont.placeAt("content");

Extending SAPUI5

Inclusion of External JS Libraries •

If UI5 doesn’t provide controls or behaviours that other JavaScript libraries offer, these libraries can be included into the UI5 based pages



Some JS libraries are already included in UI5 and used by UI5 runtime and can be used without additional loading, e.g.: o jQuery, jQuery UI o dataJS, a Microsoft driven oData library which handles requests and takes care of creating and handling requests in JSON and XML format o D3, an SVG-based graphical library to visualize data sets



Other libraries need to be loaded separately, another library of interest is o Flot, a -based jQuery plug-in for displaying data sets

© 2014 SAP AG. All rights reserved.

234

Inclusion of External JS Libraries •

To show how to load and use an external library, we take a look at an example using Flot: o One can place the script tags for the library just behind the UI5 bootstrap script tag in the HTML tag. o the library can be downloaded and made part of the application project: ►For pie chart support you need also the flot.pie.js plugin

 You can see the pie chart example here

© 2014 SAP AG. All rights reserved.

235

Inclusion of External JS Libraries  Most libraries require a starting point or a placeholder  This HTML element can be provided by using the UI5 HTML control

Exercise 18

// create the HTML control which will be a placeholder var oHTML = new sap.ui.core.HTML({ id: "pieContainer“, content: "
