Is it possible to detect event of an element on runtime without
explicitly attaching event by using onClick() etc?.
I have a page which can generate run time DIVs and form elements and I
don't even have their names or Ids for reference. Is it possible in
Javascript to capture which element was clicked and then can refer
that element by returning it's ID or tag type?
Yes, through event bubbling[1]. The event has to bubble (`click' does in
the standard DOM and all known proprietary DOMs), and one parent element has
to have an event listener attached for the event. For example:
....
<head>
<meta http-equiv="Content-Script-Type" content="text/javascript"></meta>
<script type="text/css">
// <![CDATA[
function clickHandler(e)
{
if (e)
{
var t = e.target || e.srcElement;
if (t) window.alert(t.id);
}
}
// ]]>
</script>
</head>
<body onclick="clickHandler(event)">
...
<div id="foo">
...
</div>
...
</body>
....
As you can see, once you have the element object reference (t), you don't
need the ID or its element type ("tag name") anymore to refer to it.
