Using jQuery UI So far in this chapter, w GS1 - 12 for None e"ve seen how to download the jQuery UI package, how jQuery UI can be customized prior to downloading, and the basic theming constructs. Now we"re ready to start building user interfaces so we can see themes in action..

Time for action - using widgets We"re now going to create GS1 - 12 for None our first themeable jQuery UI interface. It will be a simple one at that a button widget, when clicked, displays a dialog widget:. Create a new index.html f ile with the following content:. <html xmlns="http://ww Software UPC A"> <head> <title>Hello Dialog</title> <link href="jqueryui/css/ui-lightness/jquery-ui1.


css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="jqueryui/js/jquery1.5.x.

js"></script> </head> <body style="font-size: 10px;"> <button id="btn_hello">Say Hello</button> <div id="dlg_hello">Hello World!</div> </body> </html>. 2. 3..

Make sure there is a jque ryui folder in the same folder as index.html. It should have the same contents as was extracted from the jQuery UI package downloaded earlier in the chapter.

Create a new index.js file with the following content:. $(document).ready(functio upc a for None n(){ $("#dlg_hello").dialog( { autoOpen: false }); $("#btn_hello").

button().click(function(){ $("#dlg_hello"). dialog("open"); }); });.

Open index.html in a web browser. You should see a Say Hello button:.

Clicking on the Say Hello UCC - 12 for None button should open a dialog widget, seen as follows:. [ 34 ]. 2 . What just happened We"ve just cr UPC-A for None eated our first two widgets with jQuery UI! We"ve created two new files to implement our example - index.html defines our page structure and defines the JavaScript used to create the widgets. In index.

html, we set a global style setting in the body element font-size: 10px;. This will set the font size to 10px for any elements displayed on this page, including jQuery UI widgets. The reason we"re setting this style property here is because this is an example and we don"t want to set up a new style sheet for just one property.

Inside the body tag, we have two elements - a button and a div: The button element serves as a template for the button widget. The code in index. js $("btn_hello").

button() creates the widget. The div element serves as a template for the dialog widget. The code in index.

js $("dlg_hello").dialog() creates the widget. You"ll notice that everything in the index.

js module is surrounded by a $(document). ready() callback function. This is important; we cannot create our widgets until the page has finished loading.

Any jQuery UI widget relies on an HTML element its template. If the template isn"t ready, jQuery UI doesn"t know how to create the widget. Creating widgets inside $(document).

ready() is a safe way to ensure the required HTML elements are available. The first widget we create is the dialog. When our example page loads, you"ll notice that the dialog div isn"t displayed anywhere.

This is because we"ve passed an option to the dialog constructor, autoOpen, which tells it to remain hidden initially. The second widget created is the button. We don"t pass any arguments to the button constructor.

The .button() call returns a copy of the button widget. On the same line, we use .

click() to tell the button we want something to happen when the user clicks on the button. In our example, our supplied function to .click() displays the dialog widget by calling .
