Use jquery to obtain the value of an element in the parent window in IFRAME.

Using jquery to get the value of an element in the parent window in IFRAME, we have to use the DOM method and jquery method to achieve this.

1. In the parent window, select all radio buttons in IFRAME.
$ (Window. Frames ["iframe1" cmd.doc ument). Find ("input [@ type = 'Radio ']"). ATTR ("checked", "true ");

2. in IFRAME, select all radio buttons in the parent window
Vertex (w.w.parent.doc ument). Find ("input [@ type = 'Radio ']"). ATTR ("checked", "true ");

IFRAME framework: <IFRAME src = "test.html" id = "iframe1" width = "700" Height = "300" frameborder = "0" scrolling = "Auto"> </iframe>

IE7 passed the test

The implementation principle is actually very simple. $ (DOM object)Can be converted Jquery object
