Hello I am trying to create a horizontal tab menu with java script and html.
I want one of the tabs "terms" to appear on its on state by default when page loads. How do I do that. I have already created the rollover images. How do I get one of the tabs to be on the rolled over image by default?

<SCRIPT LANGUAGE="JavaScript">
image1 = new Image();
image1.src = "images/nav1_on.gif";

image2 = new Image();
image2.src = "images/nav2_on.gif";

</script>

html
<a href="index.htm" onmouseover="image1.src='images/nav1_on.gif';"
onmouseout="image1.src='images/nav1_off.gif';">
<img name="image1" src="images/nav1_off.gif" border=0></a>

Could you show us a link on the page that you are referring?..
What about changing the default image on load?

Code:

<img name="image1" src="images/nav1_off.gif" border=0>

..Use images/nav1_on.gif instead

I do not have it up and running yet. but was looking for a page lode event that would select the rolover image by default

...But my point is, it has the same function as changing the image from the image tag

Anyway, you might have a reason behind it, i'll just show you this example:

HTML Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
   "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript">
window.onload = function()
{	
	document.getElementById('image1').src = 'images/nav1_on.gif';
	
	document.getElementById('clickme').onmouseover = function()
	{
	document.getElementById('image1').src = 'images/nav1_on.gif';
	}
	document.getElementById('clickme').onmouseout = function()
	{
	document.getElementById('image1').src = 'images/nav1_off.gif';
	}
}
</script> 
</head>
<body>
<a href="index.htm" id="clickme">
<img name="image1" src="images/nav1_off.gif" border=0></a>
</body>
</html>

Ideally, it has your wish of having images/nav1_on.gif as the default image during onload

Just a suggestion, you should (if possible) avoid combining presentation (JS) from markups (HTML). See example

See if it helps

Thanks I will try it out. Its an assignment and unfortunately that short cut of just swithcinh the image has been banned. one uestion why should I avoid combining the two? Whats the problems?

Problem?..not really a problem, it's just to make your HTML more simple to look

There are some validation errors that results in placing JS in Markups, anyway this will not bug you.
