有效的html-之间的&#39;&lt;&#39;或&#39;&gt;&#39; <script>tags

Question

When I use the html validator:

http://validator.w3.org/

It gives me an error. In the header of my page, I have something like this:

<script type="text/javascript"> 
$(document).ready(function(){
    $('#countdown').countdown({
        until: '+2d+3h+1m+6s',
        layout: '{d<}{dn} {dl}, {d>}{hnn}:{mnn}:{snn}'
    });
});
</script>

The part within layout that is given a string contains a < . The validator is giving an error.

Do I just discount this, since it's part of a script tag? Is it something with the validator?

I know some might suggest putting it in an external file, but it's dynamic and I don't want to figure that out.

Answer 1

You wrap it with CDATA

<script type="text/javascript"> 
//<![CDATA[
$(document).ready(function(){
    $('#countdown').countdown({
        until: '+2d+3h+1m+6s',
        layout: '{d<}{dn} {dl}, {d>}{hnn}:{mnn}:{snn}'
    });
});
//]]>
</script>

Answer 2

As mentioned in the HTML 4 Recommendation's note about specifying non-HTML data in element content, end tags are recognized within SCRIPT elements, but other kinds of markup --such as start tags and comments--are not. This is an unintuitive quirk of SGML for elements defined to have CDATA content.

Try

    <script type="text/javascript"> 
$(document).ready(function(){
    $('#countdown').countdown({
        until: '+2d+3h+1m+6s',
        layout: '{d<}{dn} {dl}, {d\>}{hnn}:{mnn}:{snn}'
    });
});
</script>
