JQuery UI - Using Widgets Polymorphically

Question

I was planning on creating several widgets using JQuery UI, and use them polymorphically.

So, say I have two widgets called widget_1 and widget_2, both of which define a "public" method called testMethod(). I would like to blindly take either object and call the testMethod. Something like:

widget.testMethod()

However, JQuery seems to require that I know which object I have since the syntax for calling a method uses the form:

$("#widget_1").widget_1("testMethod"); 

and

$("#widget_2").widget_2("testMethod"); 

Are there any other options I have to be able to use widgets polymorphically?

Thanks.
