Get Request Attributes in JavaScript

Using the following should work.

var jsAtt = '${myAtt}';

I think I stumbled across issues because of trying to dynamically generate the string based off my needs, which JavaScript seems to not like. For example, this would have issues:

var counter = 1;
var jsAtt = '${myAtt' + counter + '}';

JavaScript seems to recognize the request parameter syntax, but only if it's completely predetermined.
