    Hi

    I have a javascript in my document whic contains "<" like this:

    
if(document.getElementById('user_comment').value.length < 10)
    PHP:
    even though it is inside an script tag still xhtml gives me a warning. What do I do then?

    If you want to validate XHTML, you must use this style for your JavaScripts:

    
<script type="text/javascript">
//<![CDATA[

alert("<This is compatible with XHTML>");

//]]>
</script>
    HTML:

    Alternatively, you could externalize your code snippet into a Javascript file so that it's separate from your output code.

    Something like this in your <head> tag:
    
<script type="text/javascript" src="form_validation_by_mahmood.js">
<!--
<![CDATA[
]]>
-->
</script>
    Code (markup):
    form_validation_by_mahmood.js would contain your function.

    From there, you'd just call your function the same as you normally would (assuming you put your JScript into a function.)

    Personally, I recommend doing this, since it separates your Javascript output from your HTML output, thus making it easier to debug. I'm also not sure, but I remember reading somewhere that JScripts tend to perform slightly more efficiently this way, especially in situations where the JScript can be cached.
