[jquery] jQuery - trapping tab select event

I'm a jQuery noob and I'm trying to figure out how to trap the tab selected event. Using jQuery 1.2.3 and corresponding jQuery UI tabs (not my choice and I have no control over it). It's a nested tab with the first level div name - tabs. This is how I initialized the tabs

$(function() {
       $('#tabs ul').tabs();
});

$(document).ready(function(){
    $('#tabs ul').tabs('select', 0); 
}); 

I'm not able to figure out how to trap any of the events or properties (selected tab, when tab clicked, etc). Would appreciate any help on this...

I tried things like:

$('#tabs ul').bind('tabsselect', function(event, ui) {
    selectedTab = ui.index;
    alert('selectedTab : ' + selectedTab);
});

              (OR)

$('#tabs').bind('tabsselect', function(event, ui) {

with no success.

Below is the markup

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

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

</DIV>

The answer is


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.

From what I can tell, per the documentation here: http://jqueryui.com/demos/tabs/#event-select, it seems as though you're not quite initializing it right. The demos state that you need a main wrapped <div> element, with a <ul> or possibly <ol> element representing the tabs, and then an element for each tab page (presumable a <div> or <p>, possibly a <section> if we're using HTML5). Then you call $().tabs() on the main <div>, not the <ul> element.

After that, you can bind to the tabsselect event no problem. Check out this fiddle for basic, basic example:

http://jsfiddle.net/KE96S/


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());
                    }
});

Simply use the on click event for tab shown.

$(document).on('shown.bs.tab', 'a[href="#tab"]', function (){
});

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
