...but did you try widget.value.length() like Simone suggested?
widget.value will return you a java.lang.String object. From there you
can just follow the standard java.lang.String API, for instance call
the length() method to get the number of characters.

This is just the JavaScript interpreter's way of representing the
java.lang.String.length() method as a string. The bit that's commented
out is simply the method signature, telling you what arguments are
expected and what will be returned.
