change class name with js

I have menu list that contains:

<ul class="content_menu tabs">
        <a href="#" name="content_1" class="tab active"><li class="pager_link_0_active"></li></a>
        <a href="#" name="content_2" class="tab"> <li class="pager_link_1"></li></a>
        <a href="#" name="content_3" class="tab"><li class="pager_link_2"></li></a>
        <a href="#" name="content_4" class="tab"><li class="pager_link_3"></li></a>
        <a href="#" name="content_5" class="tab"><li class="pager_link_4"></li></a>
        <a href="#" name="content_6" class="tab"><li class="pager_link_5"></li></a>
        <a href="#" name="content_7" class="tab"><li class="pager_link_6"></li></a>
        <a href="#" name="content_8" class="tab"><li class="pager_link_7"></li></a> 
        <a href="#" name="content_9" class="tab"><li class="pager_link_8"></li></a>                                              
</ul>

What I want to do is when particular link is clicked I need to remove active from li class name that contains active (e.g pager_link_0_active) and add active to the li that is clicked (e.g pager_link_2_active)

I know there is one way to make it:

$(".active").removeClass("active");

$(this).addClass("active");

but in my situation, active is not seperated, it is part of class name.

According to standards ul can contain only element but what you want can be achived these way:

        $(function () {
            $('ul.content_menu.tabs a.tab').click(function () {
                var newActive = $(this);

                if (newActive.hasClass('active')) {
                    return;
                }

                var oldActive = $('ul.content_menu.tabs a.tab.active');
                oldActive.removeClass('active');
                var oldIndex = $('ul.content_menu.tabs a.tab').index(oldActive);
                oldActive.children().attr('class', 'pager_link_' + oldIndex);

                var newIndex = $('ul.content_menu.tabs a.tab').index(newActive);
                newActive.addClass('active');
                newActive.children().attr('class', 'pager_link_' + newIndex + '_active');
            });
        });

It would be better to make it a separate class <li class="pager_link_1 pager_active">, then you can remove and add pager_active easily.

If the LI will always have just one class, try this:

var active_li = $(".active li");
var active_class = active_li.attr("class");
active_li.attr("class", active_attr.replace("_active", "");
var this_li = $(this).children("li");
var this_class = this_li.attr("class");
this_li.attr("class", this_class+"_active");
