I'm working in a template environment, and I can't change the <body onLoad> tag (it already had a muti-use function on it.
On the specific page I'm working on, I need some layer visibilities changed (dependant on a cookie) which seemingly can only can be done in the onLoad event.
so I need to add to or capture the onLoad for one page, and no others with a script included in the body data? (and of course it needs to be cross-broswer compliant 5+)
or is this impossible?
there are a few ways:
-------------------------------
</body>
<script language="javascript">
document.onload= yourfunction
</script>
</html>
-------------------------------
or
<body onload="yourexistingfunction();nextfunction()">
-------------------------------
or you can put it into your existing function.

Unfortuantly I have also tried the document.onLoad. The only way I could get it to partialy work was to put a setTimeout on it also. This way it times for a designated time before calling the function. But even this does not work if the user is on a slower connection. Is there a better way????
document.onload = setTimeout('read_cookie()',150);

Try:
<script type="text/javascript">
<!--
window.onload = function () {alert()}
// -->
</script>
You need to use the onunload method of the Window object and you need to use an anonymous function.

Well that did work great however it causes even more of headach. You see my issue is that I need this in the JavaScript portion but I also have access to all the body tags. The problem arises when the body tag has something in it this tag overwrites it. I would just change the body tags on the site but there are like 2000 pages and that could be a headache. So is there a way to use this and not overwrite the body onLoad functions?

Try
<script type="text/javascript">
<!--
window.onunload1 = window.onunload;
window.onload = function () {window.onunload1(); alert()}
// -->
</script>

That still overwrote any function that was directly called by the body tag itself. Thanks for trying I am just going to have to put this into the body tag.
IE here is the full issue if anyone else knows of solution.
<script language="JavaScript">
function init(){
// do some initializing of stuff.
}
function something(){
// do something else
}
window.onunload1 = window.onunload;
window.onload = function () {window.onunload1(); something()}
// -->
</script>
<body onLoad="init()">
Now normally you would just change the body tag but this body tag is in a template and included with cold fusion on several pages IE over 1000. I wrote a menu that needs to be initilized but not by putting this in the body tag. I think that I will just have to though because no other solutions are working. The solution above works but overwrites the init in the body tag.

Can you edit your init() function with ease?

I think the easiest solution is to default the variable for the header to call the menu. Then on the other pages I will just have to change the body tag. I checked through the website and this came out to be roughly 65 pages. Not too bad still a ton but not as bad as I thought originally. Wish there was a different solution though.

in this example, where do i put the name of the function i'm trying to call?
<script type="text/javascript">
<!--
window.onload = function () {alert()}
// -->
</script>
do i need to include the "unload" stuff?
thanks
