jquery - Get Index Of Element Within UL

Question

Using jQuery, I'd like to be able to get the index of the li where the contained anchor tag's HREF equals "#All". (In this case the correct result would be 3)

<div id="tabs">
    <ul>
        <li><a href="#CPU"><span>CPU</span></a></li>
        <li><a href="#Pickup"><span>Pickup</span></a></li>
        <li><a href="#Breakfix"><span>Breakfix</span></a></li>
        <li><a href="#All"><span>All</span></a></li>
    </ul>
</div>

I have tried:

$("#tabs ul").index($("li a[href='#All']"))

...with no luck. What am I doing wrong?

Answer 1

This should do it:

var index = $("#tabs ul li").index($("li:has(a[href='#All'])"));

• You were selecting all <ul> instead of all <li>s you wanted to get the index out of.
• You have to check if the <li> element :has a link with what you want by using the :has selector, otherwise the matched element will be the <a> itself instead of the <li>.

Tested the above and it gives me the correct answer, 3, as the index is 0-based.
