甚至在单击某个项目时，如何获取该项目的索引？

Question

How do I get the index of a list item during a click even on that item?

<ul>
    <li></li>
    <li></li>
    <li></li>
    <li></li>
    <li></li>
<ul>

$('li').live('click', function(e){
    alert(e.index);
})

Thanks

Answer 1

$(document).delegate('li', 'click', function () {
    alert($(this)).index());
});

Here is a demo: http://jsfiddle.net/xERTx/1/

.live() is now depreciated as of jQuery 1.7 in favor of .on() and .delegate() (source: http://api.jquery.com/live ).

Answer 2

Have you tried the index keyword?
