For In.... Frustration!!

dalar · Oct 10, 2005

Hi guys, been working on this problem for a while now and Im exhausted.

I understand that the 'For In' loop can print out the properties and methods for a given object.

I would like to do this for the 'event' object... Using the code below I am able to extract the properties for the 'navigator' object perfectly:

for (i in navigator) {
document.write("property: " + i);
document.write(" value: " + navigator + "<br>");
}

Now, when I replace navigator with 'event' I get nothing!

for (i in event) {
document.write("property: " + i);
document.write(" value: " + event + "<br>");
}

NOTE: I have also tried window.event

Why is this and what is the correct way to get it working?

thanks for your help guys.

the event object does not exist implicitly for all browsers. e.g. in mozilla, you must pass it as an argument to the function that needs it:

Code:

<html>
	<head>
		<title>test</title>
		<script type="text/javascript">
			function showEvent(e) {
				var evt = e ? e : event;
				
				var ta = document.getElementById("output");
				
				for (p in evt) {
					ta.value += p + ":" + evt[p] + "\n";
				}
			}
			
			window.onload = function() {
				window.document.onclick = showEvent;
			}
		</script>
	</head>

	<body>
		<p>click anywhere</p>
		<textarea id="output" style="width:100%; height:30em;"></textarea>
	</body>
</html>
