This post shows a complete working HTML file as an example of triggering code to run when a tab is clicked. The .on() method is now the way that jQuery suggests that you handle events.

jQuery development history

To make something happen when the user clicks a tab can be done by giving the list element an id.

<li id="list">

Then referring to the id.

$("#list").on("click", function() {
 alert("Tab Clicked!");
});

Make sure that you are using a current version of the jQuery api. Referencing the jQuery api from Google, you can get the link here:

https://developers.google.com/speed/libraries/devguide#jquery

Here is a complete working copy of a tabbed page that triggers an alert when the horizontal tab 1 is clicked.

Simply use the on click event for tab shown.
```
$(document).on('shown.bs.tab', 'a[href="#tab"]', function (){
});
```

The correct method for capturing tab selection event is to set a function as the value for the select option when initializing the tabs (you can also set them dynamically afterwards), like so:
```
$('#tabs, #fragment-1').tabs({
  select: function(event, ui){
    // Do stuff here
  }
});
```
You can see the actual code in action here: http://jsfiddle.net/mZLDk/

Edit: With the link you gave me, I've created a test environment for jQuery 1.2.3 with jQuery UI 1.5 (I think?). Some things obviously changed from then. There wasn't a separate ui object which was separated from the original event object. The code looks something like this:
```
// Tab initialization
$('#container ul').tabs({
    select: function(event) {
        // You need Firebug or the developer tools on your browser open to see these
        console.log(event);
        // This will get you the index of the tab you selected
        console.log(event.options.selected);
        // And this will get you it's name
        console.log(event.tab.text);
    }
});
```
Phew. If there's anything to learn here, it's that supporting legacy code is hard. See the jsfiddle for more: http://jsfiddle.net/qCfnL/1/

Edit: For those who is using newer version of jQuery, try the following:
```
$("#tabs").tabs({
    activate: function (event, ui) {
        console.log(event);
    }
});
```

Simply:

$("#tabs_div").tabs();
$("#tabs_div").on("click", "a.tab_a", function(){
    console.log("selected tab id: " + $(this).attr("href"));
    console.log("selected tab name: " + $(this).find("span").text());
});

But you have to add class name to your anchors named "tab_a":

<div id="tabs">
<UL>
    <LI><A class="tab_a" href="#fragment-1"><SPAN>Tab1</SPAN></A></LI>
    <LI><A class="tab_a" href="#fragment-2"><SPAN>Tab2</SPAN></A></LI>
    <LI><A class="tab_a" href="#fragment-3"><SPAN>Tab3</SPAN></A></LI>
    <LI><A class="tab_a" href="#fragment-4"><SPAN>Tab4</SPAN></A></LI>
</UL>

<DIV id=fragment-1>
<UL>
    <LI><A class="tab_a" href="#fragment-1a"><SPAN>Sub-Tab1</SPAN></A></LI>
    <LI><A class="tab_a" href="#fragment-1b"><SPAN>Sub-Tab2</SPAN></A></LI>
    <LI><A class="tab_a" href="#fragment-1c"><SPAN>Sub-Tab3</SPAN></A></LI>
</UL>
</DIV>
.
.
</DIV>

In later versions of JQuery they have changed the function from select to activate. http://api.jqueryui.com/tabs/#event-activate

it seems the old's version's of jquery ui don't support select event anymore.

This code will work with new versions:

$('.selector').tabs({
                    activate: function(event ,ui){
                        //console.log(event);
                        console.log(ui.newTab.index());
                    }
});
