Hi all,
I need some javascript code to change the value of a javascript variable when a link in clicked.

For example .. I have :

<script>

var one = '0';
...
</script>

<body>
<div id="myID">
<a href="whatever">click here</a>
</div>

So, when the link is click "IF" variable "one" is "0" then incrememnt to "1" otherwise don't do anything.

Any questions just ask.

Thanks again

Try this:

<!DOCTYPE html>
<html>
<head>
  <script src="http://code.jquery.com/jquery-1.5.js"></script>
</head>
<body>
<script>

    var one = 0;

    $(document).ready(function(){
    
            $('a[href=whatever]').click(function(e){
                one = one + 1;
                $('#variable').html(one)
                e.preventDefault();
            });
    });

</script>


<body>
<div id="myID">
<a href="whatever">click here</a>
