How do I get the text of the active
<div class="tabs">
<ul>
<li class="active"><span class="l"></span><a href="#">Standard Class</a><span class="r"> </span></li>
<li><span class="l"></span><a href="#">Bussiness Class</a><span class="r"></span></li>
<li><span class="l"></span><a href="#">Premium</a><span class="r"></span></li>
and how to I take off the class active off the non sel开发者_如何学JAVAected one and put it on the selected one with jQuery
$('.tabs a').click(function() {
$('.tabs li').removeClass('active');
(this).parent().addClass('active');
});
and for the text of the active:
$('.tabs .active a').text();
Try this:
It caches your <li> elements, so you don't need to keep selecting them from the DOM.
var $lis = $('div.tabs > ul > li').click(function() {
var text = $(this).addClass('active').text();
$lis.not(this).removeClass('active');
});
var activeText = $('.active a').text();
Live example: http://jsbin.com/uwigo4/3 (full source below)
Getting the text of the "active" one, you can use text:
var text = $('div.tabs li.active').text();
Changing which is the active one, you just removeClass and addClass as appropriate, e.g.:
jQueryObjForCurrentActiveElement.removeClass('active');
jQueryObjForNewElementToMakeActive.addClass('active');
If you're doing this in an event handler, odds are you'll want hasClass as well.
