I have a form and I use this document.forms["form-0"].answerN[0]; to select a specific radio button, however I could not manage to do it with jQuery.
I tried $('forms["form-0"]') and $('forms[0]') to get to the form but it didn’t work, and both do work using the long path..
you can access like this ( jQuery v1.6)
