javascript - chrome: problem with iframe's parent
 
Hi!

I'm developing an application on phonegap and running it on android. I want to send a meesage to a page from a double-nested iframe.

On Android 2.2 it works if I do this:

Code:

parent.parent.postMessage('whatever', '*');
But then I try on Android 4 and it doesn't work.... I checked with javascript the location of each "parent" and on Android 4 it always returns the same address of the iframe I'm trying to send the message from and in 2.2 it returns the "right" address of each iframe. Why is that?

I just performed a very simple test. I tested if window == parent. On 2.2 it's not the same... on 4.0 it is the same. Does it make any sense?

How interesting:

Is it because a phonegap application runs locally? Ugh! Is there a workaround for this?

I had tried a very small application with an iframe that sent a message to its parent. I tested it running in apache from android's browser and it works. I just tested it from inside phonegap and it fails.... so I guess "running locally" is to blame here. So.... is there a workaround? perhaps changing something in the manifest?
