I want to have both href and onclick working and I found a solution here: HTML tag <a> want to add both href and onclick working

In myFunction, I make an AJAX Request calling a perl ponent.

It works fine when I put the Javascript call in href, but not when in onclick. Unfortunately, I'm not allowed this solution neither jQuery, so can you please help.

// AJAX Request doesn't work
<a href="www.mysite" onclick="myFunction();">Item</a>

<script type="text/javascript">
    function myFunction () {
        var xmlHttp = getXMLHttpObject();
        xmlHttp.open('GET', 'perl.m', true);                
        return true;
    }
</script>

// AJAX Request ok
<a href="javascript: myFunction('www.mysite')">Item</a>

<script type="text/javascript">
    function myFunction (url) {
        var xmlHttp = getXMLHttpObject();
        xmlHttp.open('GET', 'perl.m', true);
        window.location.href = goto_url;                
    }
</script>

perl.m:
<%init>
    warn "perl.m";
    ... update ...
</%init>

Please carefully follow the tutorial. It states that you must enter the javascript like this (with return keyword).

<a href="www.mysite." onclick="return theFunction();">Item</a>

Besides that you should always type in a URL (like http://stackoverflow.).

Please let me know if this supports you.

Try with:

<a href="www.mysite." onclick="myFunction(event);">Item</a>

<script type="text/javascript">
    function myFunction (e) {
        e.preventDefault();
        var xmlHttp = getXMLHttpObject();
        xmlHttp.open('GET', 'perl.m', true);                
        return true;
    }
</script>

Because you have href attr with url, so it will go to url and your ajax is not affected. e.preventDefault() is your solution here.
