jQuery “return false” works in version 1.6 but not 1.6.1 (rails 3)

问题

The following code used to function without attempting to render a new template with jQuery verion 1.6. I installed jQuery 1.6.1 and now a radio button click results in an attempt to render a new page.

FYI, the form was submitted on each click because quite a few clients would complete part of the questions, close the browser and expect their work to be there when they came back to finish. If there is a better way, I'd love to know it.

in the application.js on development machine:

$('.submittable').live
    ('change', function() 
        {
        $(this).parents('form:first').submit();
        return false;
        }
    );

Again, this works in jQuery 1.6 but not 1.6.1. I used this tutorial as a guide.

Any help is appreciated.

UPDATE: continuation of this issue here.

Try:

$('.submittable').live('change', function(event) {
    event.preventDefault();
    $(this).parents('form:first').submit();
    return false;
});

Look at your linear chain of events... You are submitting the form every time and then trying to return false...perhaps you are looking for something like this:

$('.submittable').live('change', function(){
   if( /some condition/ ){
       $(this).parents('form:first').submit();
    } else {
       return false;
    }
 });

The problem was one version of jQuery on the production machine and another on the development machine. We changed from 1.6 full to 1.6.1 min on the development machine. When i changed it back the problem disappeared. Thanks for all your help guys. Kudos to thedaian. I'll switch the answer over to him if he posts.
