Simple Javascript Question

**Kaula** · October 11, 2006

Hi,

Heres some basic code, what I'm trying to do is pull some text from a function in the head section but you can see it seems to be showing up before its called. Not sure If I have my terminology right. Am I doing something wrong? Heres the example of what it does in a browser http://www.kaulaiscool.com/random/js_problem.htm

><html>
<head>
<title></title>
	<script type="text/javascript">
		<!--

			function why()
				{
					document.writeln("sample text");
				}

		// -->
	</script>
</head>
<body>
<script type="text/javascript">
	<!--
		document.write("Here is some" + why() );
	// -->
</script>
<noscript>
	Your Browser does not support JavaScript.
</noscript
</body>
</html>

Thanks!

I just removed the why() and added it outside of the document.write in the body and it works fine, Is that the only way to do it?

Thanks

I'm not sure but I don't think you can call a function from in a string like that or possibly just not during a document.write.

Your treating why() as if it IS a string. But why() actually PRINTS a string. What you had essentially put a writeln inside a write. Modify your why() function to say this, instead of the writeln():

function why()

{

return "sample text";

}

That should do the trick.

As a side note, I believe it's more correct to say:

than it is to say:

No for XHTML it is type="text/javascript". language= is only for html 4.01

Thanks carbonize

I had just looked that up and came here to apologize. You beat me to the correction.

Thanks for the responses, I got it all working properly now. Normally I use xhtml, I just whipped that up real quick as an example, forgot that the two where different.
