Function call and value transfer between IFRAME and the parent form

Access the txtaddress control of the iframe subform on the parent page.
Window. Frames ["ifrmapcompanydetails" 2.16.doc ument. All ("txtaddress"). value = 'address ';

Access the textbox1 control of the parent page in IFRAME subform 1, and subform 1 assigns the value to a control of subform 2.
String strvalue = "value passed from the child form to the parent page ";
The following is called in the page_load event. Of course, it can be written in a Javascript script.

this.Response.Write("<script>parent.document.all('TextBox1').value = '" + strValue + "';</script>"); this.Response.Write("<script>if( parent.document.all('TextBox2').value = '0')parent.document.all('TextBox1').value = '44';</script>"); 

The sub-form accesses the global variables in the parent form:
Parent. xxx;

Access the txtaddress control of child Form 2 in IFRAME subform 1 and assign the value to a control of child Form 2.
Window. Parent. Frames ["ifrmapcompanydetails" 2.16.doc ument. All ("txtaddress"). value = 'address ';

The parent form submits two IFRAME child forms.
Window. Frames ["ifrmapcompanydetails"]. form1.submit ();
Window. Frames ["ifrmapproductinfodetails"]. form1.submit ();

The IFRAME subform calls the Javascript event of the parent page.
Window. Parent. XXX ()

Function invokechildevent ()
{Var FRM = Document. Frames ["ifrchild1"]. childevent ();}
