Question

I am relatively new to jQuery and web development.

I am using jQuery UI Tabs to create tabs.

But I want the contents to be loaded only when I select a particular tab.

OK, I assume when the user clicks a tab, you intend to fetch content dynamically, via AJAX. This really involves two things, setting an onclick even for your tab and fetching the data via ajax.

Setting an onclick event

Give your tab an class, for example my_tab. Let’s say that when the user clicks the tab you want the handle_tab_click() function to fire. Here’s an example of binding the onclick event to your my_tab tab:

$('.my_tab').bind('click', handle_tab_click); 

Your handle_tab_click() function will be given an event argument which will be able to provide you with information on the element that fired the event (in this case, the element with class name my_tab).

function (event) {     if ($(event.target).hasClass('my_tab')) { /* handle tab click */ }     if ($(event.target).hasClass('my_tab_2')) { /* a different tab click */ }     if ($(event.target).hasClass('my_tab_3')) { /* ... */ } } 

See the JQuery event documentation for more details here.

Fetching the data via ajax

Fetching data will require you to invoke a remote script while supplying information about which tab was clicked (in order to fetch the appropriate information). In the following snippet, we’re invoking the remote script myscript.php, supplying the HTTP GET argument tab_clicked=my_tab and calling the function tab_fetch_cb when the script returns. The final parameter is the type of data being returned (it’s up to you to choose).

$.get('myscript.php', {tab_clicked, 'my_tab'}, tab_fetch_cb, 'text/json/xml') 

It’s up to you to design myscript.php to handle the tab_clicked parameter, fetch the appropriate data and return it (i.e. write it back out to the client).

Here’s an example for tab_fetch_cb:

function tab_fetch_cb(data, status) {     // populate your newly opened tab with information      // returned from myscript.php here }

I’m sorry I can’t be more specific in my examples, but a lot of the processing is really dependant on your task. As it looks as it has already been pointed out, you may look to some JQuery plugins for a canned solution to your problem. That being said, it never hurts to learn how to do this stuff manually w/ JQuery.

Good luck.
