jQuery add class .active on menu

Question

I've got a problem.

I want to add the class "active" on item menu when the relative page is on.

the menu is very simple:

<div class="menu">

<ul>
<li><a href="~/link1/">LINK 1</a>
<li><a href="~/link2/">LINK 2</a>
<li><a href="~/link3/">LINK 3</a>
</ul>

</div>

In jQuery I need to check if the url is www.xyz.com/other/link1/

if it's this one I would like to add a class one the 'a' element of link1.

I'm trying many solutions but nothing work.

What you need is you need to get window.location.pathname as mentioned and then create regexp from it and test it against navigation hrefs.

$(function(){

    var url = window.location.pathname, 
        urlRegExp = new RegExp(url.replace(/\/$/,'') + "$"); // create regexp to match current url pathname and remove trailing slash if present as it could collide with the link in navigation in case trailing slash wasn't present there
        // now grab every link from the navigation
        $('.menu a').each(function(){
            // and test its normalized href against the url pathname regexp
            if(urlRegExp.test(this.href.replace(/\/$/,''))){
                $(this).addClass('active');
            }
        });

});
