jQuery JSH

Tiny jQuery Plugin for JavaScript Syntax Highlighting

This Plugin provides Syntax Highlighting for JavaScript code. It works (to my knowledge) correct in all cases, with the exception of multiline strings (a feature of JavaScript, that hopefully nobody uses), like:

var s = "multiline \
string";

Demo

jQuery JSH Highlighting its own source

Usage

Include jQuery, the jsh-colors.css stylesheet and jquery-jsh.js script in your head element and call .jsh() for all elements you want to highlight.

<link rel="stylesheet" type="text/css" href="jsh-colors.css"/>
<script type="text/javascript" src="jquery-1.4.3.min.js"></script>
<script type="text/javascript" src="jquery-jsh.js"></script>
<script type="text/javascript">
	$(function(){
		$('pre.javascript').jsh();
	});
</script>

If you pass false to .jsh(), tabs will NOT be replaced with 4 spaces.

Note that any < > & and " characters must be alreday replaced with their HTML entities for the Syntax Highlighting to work. If this is not the case (e.g. when you're loading the source via AJAX), you can use the following JavaScript snippet to escape it:

s = s.replace(/&/g,'&amp;').replace(/</g,'&lt;').replace(/>/g,'&gt;').replace(/"/g,'&quot;');
