The HTML:

        //Here you must encapsulate the forward slash between two forward slashes; ex. ///
       //Then you must escape the forward slash with a backslash; ex. /\//
       var aText = "Flash/AS3/Flex";
       var filterVal = aText.toLowerCase().replace(/\//g,'-');

Ex.
Flash/AS3/Flex becomes flash-as3-flex

Essentially this little script will convert the text to lowercase and go through the entire text to replace all forward slashes. Hope this helps!
