Loading TabView from an External Data Source

The YUI TabView provides a built-in way to load external data.

Because our content depends on JavaScript, in this case we will build our TabView entirely from script. First create a container to insert our new TabView into. This can be any existing element on the page, including the <body>, but for this example, we will create a <div> called container:

1<div id="container"><h2>Browser News</h2></div> 
view plain | print | ?

Next we will create a TabView instance, omitting the element argument, which signals the constructor to create the TabView container:

1var tabView = new YAHOO.widget.TabView(); 
view plain | print | ?

Next we add tabs to our TabView, including the label and a dataSrcpointing to the content, setting the default selected tab to "active". To minimize the number of requests, we will set each cacheData for each Tab.

1tabView.addTab( new YAHOO.widget.Tab({ 
2    label: 'Opera', 
3    dataSrc: 'assets//news.php?&query=opera+browser', 
4    cacheData: true, 
5    active: true 
6})); 
7 
8tabView.addTab( new YAHOO.widget.Tab({ 
9    label: 'Firefox', 
10    dataSrc: 'assets//news.php?&query=firefox+browser', 
11    cacheData: true 
12})); 
13 
14tabView.addTab( new YAHOO.widget.Tab({ 
15    label: 'Explorer', 
16    dataSrc: 'assets//news.php?&query=microsoft+explorer+browser', 
17    cacheData: true 
18})); 
19 
20tabView.addTab( new YAHOO.widget.Tab({ 
21    label: 'Safari', 
22    dataSrc: 'assets//news.php?&query=apple+safari+browser', 
23    cacheData: true 
24})); 
view plain | print | ?

All that is left is to append our new TabView to our container:

1tabView.appendTo('container'); 
view plain | print | ?

This is a basic example of how to load content from an external source into a TabView widget.
