Question

just starting to get my hands dirty with the jQuery goodness and the first task i’m trying to tackle is to underline a link after it has been clicked. Naturally, after a different link in the same div was clicked the previous one is no longer underlined…

Answer 1

So basically, you are wanting a kind of navigation menu that changes the style of the link once clicked. First, make a style that just underlines:

<style type="text/css">
a.currentlyActive
{
  text-decoration: underline;
}
</style>

The code you will be modifying is…

<a class="navigation" href="#">My First Link</a>
<a class="navigation" href="#">My Second Link</a>
<a class="navigation" href="#">My Third Link</a>

Just a few links with some type of class that denotes that it is the links u want to underline and not underline.

Next, add a little jQuery magic to apply the style upon clicking. And at the same time, you will want to remove the style from all others.

<script type="text/javascript">
$(function() {
  $('.navigation').click(function() {
    // this removes the underline class from all other ".navigation" links.
    $('.navigation').removeClass('currentlyActive');

    // this makes the one that was clicked underlined
    $(this).addClass('currentlyActive');
  });
});
</script>

And, that’s it. I tried to as verbose as possible to explain what each step does. Obviously, you can makes the class names shorter and remove the comments to make it small and lean.
