Example A: code:
<script language='javascript' type='text/plain'>
<!--
... javascript here
//-->
</script>
1) Should the language attribute be 'javascript' or 'Javascript'? 2) Is the type attribute recommended? Example B: code:
[qb]<body onload="javascript:window.location='http://example.com/';"> 3) Is the 'javascript:' prefix required here? 4) Should the attribute be 'onload' or 'onLoad'?

1. It doesn't matter, but type should be text/javascript, not text/plain  2. Yes, it's actually required 3. No 4. onload.

quote:
4.8 Script and Style elementsIn XHTML, the script and style elements are declared as having #PCDATA content. As a result, < and & will be treated as the start of markup, and entities such as < and & will be recognized as entity references by the XML processor to < and & respectively. Wrapping the content of the script or style element within a CDATA marked section avoids the expansion of these entities. code:
[qb]<script>
<![CDATA[
... unescaped script content ...
]]>
</script> CDATA sections are recognized by the XML processor and appear as nodes in the Document Object Model, see Section 1.3 of the DOM Level 1 Recommendation [DOM] [p.29] . An alternative is to use external script and style documents.

I used: <script type="text/javascript">
<![CDATA[
something
]]>
</script> And it simply didn't do the "something", it ignored it. The best way is

LK - thanks for answering my questions. What is this CDATA stuff? Does that matter for what I'm doing?

IE6 does not support XHTML - it just fakes it. Try serving it an XHTML page served as text/xml...

If the most used browser (>90%) doesn't support it, I don't see any reason to use it for 1/10 of your visitors

@LK; You must select one; a cr@p browser or standards? @Dave; XHTML is an extended version of HTML 4.01 and it uses some XML specifications... If your javascript has some '&' or '<' in it, you must either convert them to & and < or escape them with CDATA... http://www.w3.org/TR/xhtml1/ You can get the manual in pdf format => http://www.w3.org/TR/xhtml1/xhtml1.pdf

jeologic: If your javascript has some '&' or '<' in it, you must either convert them to & and < or escape them with CDATA...I assume that applies only when those characters are used in strings representing URLs, and not when they're used as Javascript operators, e.g., if (x < 5)? I'm still not clear whether this applies to my questions in the first post.
