IFRAME nesting subpage passed value to parent page Asp.net

In the nested page, for example, to pass an image1.src = str_url, you must pass image1.src to the parent page.

Method :..........

Image1.src = str_url;

String url1 = "<SCRIPT> parent.doc ument. form1.pc1. value = '" + newname + "' </SCRIPT> ";
Response. Write (url1 );

....................

CodeExplanation: pC1 is only an HTM control placed in the hidden domain of the ambush page, that is, it is temporarily written to pc1.value. The controls on the parent page are all received and the following cannot be done! Haha
