TabView Control: Getting Content from an External Source

This demonstrates how to load Tab content from an external data source.

View example in new window.

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.
