为什么W3验证程序在<script> tag and raise errors?

Question

I am trying to validate my page using the W3C validator but it keeps looking within the script tag of the javascript and failing. any ideas?

Answer 1

It gets treated as PCDATA since it's XHTML ( XML ). Mark it as CDATA per When is a CDATA section necessary within a script tag? and you should be ok:

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

Alternatively you can stop attempting to use XHTML by using HTML 5, or throw the code in an external JS file if it's feasible.
