Disabling links using Javascript

Replace the a node by the text node in the a element:

myANode.parentNode.replaceChild(myANode.firstChild, myANode);

This makes the a element to an ordinary text node.

<a href="javascript:void(0)">Useless Link</a>

With jquery:

// this prevents the code to execute before the DOM Tree is ready
$(document).ready(function(){

    // when clicking #mylink, execute this function
    $('#mylink').click(function(e){
        e.preventDefault();
    });
});

With #mylink being the element's id attribute. You can download jquery here and call it with something like:

<script type="text/javascript" src="js/jquery.js"></script>

assuming you named your jquery file: jquery.js and put it in a folder named js.

All you have to do is change the href property to a value you are happy with, e.g.

aLink.href = '';

To do every link in the document:

var links = document.links;
for (var i=0, iLen=links.length; i<iLen; i++) {
  links[i].href = '';
}
