Rails app refreshing on localhost - event.returnValue is deprecated warning

Question

My Rails app on localhost started randomly refreshing when using the 'back' browser arrow. Chrome(31.0.1650.48) console reads:

event.returnValue is deprecated. Please use the standard event.preventDefault() instead. 

I guess these issues are connected.

I also found this recent issue on jQuery bugtracker. Funny thing, but 10 hours ago everything was fine.

Anyone experiencing similar problems? What are the options?

EDIT: although I was browsing my app on localhost, I found out that a number of production websites are experiencing the same problem, showing the same console output, including 37signals

Answer 1

I believe this is largely due to the newest version of Chrome that you are using. I haven't found the exact details but it appears that Chrome has decided to deprecate this property which is currently used by jQuery.

Since it's just a deprecation, nothing will be broken yet, but it does mean that it will be removed in the future. Once jQuery fixes the issue you should probably try to update.

Edit: Sorry I missed the point - I would assume that the random refreshing is unrelated to the message you are seeing about event.returnValue

Check this link out Looks like the native js method 'event.returnValue' has been marked as deprecated in newer Chrome versions. http://bugs.jquery.com/ticket/14320
