&gt; +        var colonIndex = text.indexOf(&quot;:&quot;);</span >

What if this returns -1?

&gt; +        var match = /(?:[^:;\s]\s*)+/.exec(remaining);</span >

You can do this without doing a substring. If you make the regex, then set regex.lastIndex = colonIndex, it will only search after that.</pre>
