[removed] Adding an onClick handler without overwriting the existing one

Question

I\'m trying to modify all links on a page so they perform some additional work when they are clicked.

A trivial approach might be something like this:

Answer 1

This function should be usable (event listeners approach):

function addEventListener(element, eventType, eventHandler, useCapture) {
    if (element.addEventListener) {
        element.addEventListener(eventType, eventHandler, useCapture);
        return true;
    } else if (element.attachEvent) {
        return element.attachEvent('on' + eventType, eventHandler);
    }
    element['on' + eventType] = eventHandler;
}

or you can save some more code adding this function (if you need to add the same event listener to many elements):

function addClickListener(element) {
    addEventListener(element, 'click', clickHandler, false);
}
