Does onclick work the same way?

Yes, all dom events should be assignable this way.

Also, via closure, you can use a parameter to set the string:function setTip(tipString){document.getElementById("reqPic").onclick = function() { Tip(tipString); };}This is one of my very favorite Javascript features.

Answer 2

A:

You could have an onload event on your body tag which calls a function that checks necessary values.

<script type="text/javascript">
var isToolTipEnabled = true;
function eventAdder() {
    if (isToolTipEnabled) {
        var img = document.getElementById('reqPic');
        img.onmouseover = function() {
            Tip('string');
        }
        img.onmouseout = whateverElse;
    }
}
</script>
<body onload="eventAdder();">
