I inserted some js code (provided by a third party service) in my webpage and it broke my html validation. How can I fix the problem? CDATA isn't doing the trick. This is my sample snippet:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>test</title>
<script type="text/javascript">
/*<![CDATA[*/
document.write('<script src="//sharebutton.net/plugin/sharebutton.php?type=horizontal&u=' + encodeURIComponent(document.location.href) + '"></scr' + 'ipt>');
/*]]>*/
</script>
</head>
<body>
<p>test</p>
</body>
</html>
And here you can find the result of the validator.
<![CDATA[*
is a feature of XML, not HTML. It is just part of the text content of the script element in HTML terms.
To safely include the string </script>
in a JavaScript string literal in HTML: Escape the slash:
'"><\/script>')
