将iframe javascript代码注入父窗口

Question

I need iframe js code to be part of the parent window. there is a way?

Answer 1

In my case this worked perfectly.

<script type="text/javascript"> 
  var wnd = window;
  if(wnd.parent){
    wnd = wnd.parent;
  }
  wnd.$.globalEval('$.unblockUI();Dialog.hide();');
</script>

This ofcourse uses jquery, but all it does is calls execScript or eval on the current window. I don't think there is a better way do this.

Answer 2

Calling from parent to iframe:

Suppose that your frame is called "myTargetFrame" and the function you're going to call is myFunction():

document.getElementById('myTargetFrame').contentWindow.myFunction();

You can use also window.frames instead of document.getElementById

Calling from iframe to parent:

parent.document.formname.fieldname.value = [value you want to set]

Hope it helps
