Javascript not executing on window load 1

jwhite68 · Jun 14, 2007

When the window loads, it is supposed to execute a piece of Javascript, which highlights a button, and displays links below it.

Here is the code segment for the window load.

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<HTML>
<HEAD>
<TITLE>homepage</TITLE>
<link href="main.css" rel="stylesheet" type="text/css">
<link href="ddmenu.css" rel="stylesheet" type="text/css">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript" src="js/services.js"></script>
<script type="text/javascript">
	window.onload = function () { requestProd(); }
	window.onload = function () { setTimeout('clearPreloadPage()',0); }
</script>
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
	function clearPreloadPage() 
	{ //DOM
		if (document.getElementById)
		{
			document.getElementById('prepage').style.visibility='hidden';
			document.getElementById('servcountry').style.visibility='visible';
		}
		else
		{
			if (document.layers)
			{ //NS4
				document.prepage.visibility = 'hidden';
				document.servcountry.visibility = 'visible';
			}
			else 
			{ //IE4
				document.all.prepage.style.visibility = 'hidden';
				document.all.servcountry.style.visibility = 'visible';
			}
		}
	}
// End -->
</SCRIPT>

So it is supposed to execute requestProd().

RequestProd() is defined in a file called service.js as:

Code:

function requestProd() {
	document.imgProd.src = 'elements/products1.gif';
	document.imgServ.src = 'elements/services0.gif';
	document.imgEven.src = 'elements/events0.gif';
	document.forms['prods'].find.value = 'products';
	if (!oIFrame) {
		createIFrame();
		setTimeout(requestLinks, 10);
		return;
	}
	var sCountry = document.getElementById("servcountry").value;
	var sServ = document.getElementById("find").value;
	oIFrame.location = "requestlinks.php?find=" + sServ + "&country=" + sCountry;
}

Here are 3 buttons, one of which (the one for Products), should get automatically invoked by the window load:

Code:

<td><a href="#srv"><img src="elements/services0.gif" border="0" name="imgServ" id="imgServ" onclick="requestServ()" /></a></td>
						<td><a href="#srv"><img src="elements/events0.gif" border="0" name="imgEven" id="imgEven" onclick="requestEven()" /></a></td>
						<td><a href="#srv"><img src="elements/products1.gif" border="0" name="imgProd" id="imgProd" onclick="requestProd()" /></a></td>
						<td>

Can anyone think of a reason why the execution of the window load for requestProd() doesnt work?

You can only call one .onload per page. You will have to mix these two statements into one.

Code:

window.onload = function() {requestProd(); clearPreloadPage(); }
