Method:

1: Click on the parent page test.aspx <input type= "button" id= "Btnshow" onclick= "ShowItem" (); " Value= the "Show subform"/> button to trigger, and then:

<script language= "javascript" type= "Text/javascript" >
function ShowItem () {

var win = window.open ("test2.aspx", NULL, "height=300,width=450, left=300px,top=20px, Menubar=no,titlebar=no, Scrollbar=no,toolbar=no, Status=no,location=no ");

}

2: Click on the child page test2.aspx <input type= "button" id= "Btnselect" onclick= "check ();" Value= the "Select"/> button to trigger, and then:

<script language= "javascript" type= "Text/javascript" >
function Check () {

Window.opener.document.getElementById ("txtID"). Value=id;
Window.opener.document.getElementById ("Txtname"). Value=name;

}

In this way, the document.getElementById ("txtID") and document.getElementById ("Txtname") 2 controls of the parent page can get the return value of the child page.
