manipulating frame url by script

[Gadjoken]

Hello,

Did you manage to update your url from this script? 
Indeed I am trying to display a URL contained in a string type object and I cannot update the FRAME from this JS.
here is my script:

Code:

$(function(){
  if (typeof grp != 'undefined') {
      var URL= grp.getvalue('34/1/1');
      $('.testurl').find('iframe').attr('src', URL);
  }
});

I did add in Additional classes testurl but the FRAME remains on the URL that I entered manually in the object (34/1/1).


Thanks for your feedback.

B.R.
