Passing data between frames with Javascript

Question

I\'ve setup a simple example at http://ryanmalin.co.uk/frames/

If you press \"add\" it will paste the form data from the left frame into the right frame.

Whe

Answer 1

This is not possible. It's a deliberate browser restriction for security.

Answer 2

See the "Same Origin Policy" for a description of how inter frame security works. In a nutshell, there is very little communication allowed between frames on a different domain for security reasons. You cannot make any direct Javascript calls between frames on different domains.

HTML5 has a new messaging system that can safely communicate data (not direct JS calls) between cooperating frames in different domains. See here and here for a description of how the HTML5 messaging works.
