timeout user inactivity script error

ayva · Jan 12, 2009

I have this script that redirects if users mouse or scrollbar is inactive for a time. Works on my mac, but on IE6 on a pc with xp, I get errors- 'time1' is undefined
do I need to do something special for IE?
any ideas?

thanks!

<script type="text/javascript">

</script>

<body bgcolor="#ffffff" onload="timer();
MM_preloadImages('images/Chipcreelink_roll.gif','images
/crowlink_roll.gif','images/ncheylink_roll.gif','images
/WIwhclink_roll.gif','images/purchaselink_roll.gif','images
/dvdscdslink_roll.gif','images/contactslink_roll.gif','images
/WIaithplink_roll.gif','images/thanks_roll.gif')" onmousemove="detime()"
onscroll="detime()">

I am on a Linux box, so I can't test this for you...but I believe that the time1 variable is declared locally. Firefox may be a little more forgiving than IE, so I suggest you try adding this:

Code:

var time1 = 0;
function timer() {
...
}

This way time1 is declared and any reference to time1 will update the global time1 variable.

I'd say you want to check (in "detime") whether a timer has been started or not, as "doscroll" is probably being called before the page has loaded. Something like this:

Code:

<script type="text/javascript">

	var time1 = null;

	function timer() {
		time1 = window.setTimeout('redirect();', 1000000);
	}

	function redirect() {
		window.location = 'logout.php';
	}

	function detime() {
		if (time1 !=null) {
			window.clearTimeout(time1);
			time1 = null;
		}
		timer();
	}
</script>

Hope this helps,
