Document.write page size limit?

Sorry if this has been addressed in the past, but I'm new to this forum. I'm having a problem with what appears to be a character limit on document.write usage. The following, simple code snippet works, but if 1 or more characters are added to the text (list of dashes), then the popup box does not work. This seems to be the case in IE, but not in firefox.

Does anyone know a way around this for IE?

Thanks!

Code:

<html><head>
<SCRIPT language="javascript">
function openPage(pageHtml) {
var newWin = window.open("","","width=600,height=420,scrollbars=yes,left=300,top=0  ");
newWin.document.open();
newWin.document.write(pageHtml);
newWin.document.close();
}
</script>
</head>
<body>
<table>
<tr><td>Test Link</td><td><a
href='javascript:openPage("<html><body>

Can I just ask why you are using JavaScript to build an entire page
like that anyway? Surely it would be easier to just build the page
in HTML, open it, and use script to manipulate it accordingly...

No particular reason, I originally had it all in HTML, then just tried to see if putting the code in javascript would make a difference. No luck, though.

I wouldn't have thought doing it in JS would be a good idea.

You are quite likely to run into some issues with escaped quotes.

Yeah, escaped quotes have definitely been a problem.

Looks like it might be a limit of 860 characters per write or writeln call. I'm going to try to split into multiple calls.

okay, now it looks like it's a limit on the number of characters in the href attribute. Not sure where I got 860 from above, it's really more like 2082.

Move it out of the href attribute then.

Code:

<a href="javascript:;" onclick="functionCall('...');">...</a>

after looking around, the problem is the URL length limit in IE is 2083 characters.

Found link on Microsoft site (Help and Support), but can't show it here as I am being blocked from doing so.

thanks for the responses!!
