Clicky Prototype = JavaScript error

When a theme/plugin uses prototype.js and “Track Names” is on, JavaSCript error occurs:

Error: ca[i].indexOf is not a function

The problem is that for (var i in something) without any checks is not safe with Prototype as it extends Arrays with its own methods.

Here’s the patch that solves this issue:

 	<script type='text/javascript'>

+		for( var i=0; i<len; ++i ) {
 			if( ca[i].indexOf( name+'=' ) != -1 )
 				return decodeURIComponent( ca[i].split('=')[1] );
 		}

Hope that helps.
