Toggle active class in nav bar with JQuery

Question

<ul>
                <li id="tabHome" class="active"><a href="@Href("~")">Home</a></li>
                <li id="tabCMDS"  ><a href="@Href("~/CMDS")">CMDS</a></li>
                <li id="tabServiceMonitor" ><a href="@Href("~/Monitor")">Service Monitor</a></li>
                <li id="tabBatchInterface" ><a href="@Href("~/BatchInterface")">Batch Interface</a></li>
            </ul>

So I wanted to bind to click of each of these Id's, and set class="active" on the one that was clicked, and remove it from all others.

I can do the first part, but how can I do the latter?

Answer 1

$(function() {
   $("li").click(function() {
      // remove classes from all
      $("li").removeClass("active");
      // add class to the one we clicked
      $(this).addClass("active");
   });
});

It would be wise to give meaningful classes to the <li>'s so you can properly select just those, but you get the idea.

Answer 2

No need to bind a click event to each ID but instead bind to all of the list items of this unordered list. Then use the .parent().children() methods. Following should work:

$('ul li').click(function(){
  $(this).addClass('active');
  $(this).parent().children('li').not(this).removeClass('active');
});
