如何在子页面中访问父窗口元素

Question

I have a Main page(Parent) and one pop up page(Child Page) on it, i want to pass an XML string from Parent page to Child page. when i tried to do it with query string i got this following Error.

"A Potentially dangerous Request.QueryString value was detected from the client"

Can any one knows others ways to pass data from Parent to child page.

Thanks in Advance Nitesh katare

Answer 1

If all you want is to pass a string, why don't you declare a global function in the parent window?

PARENT PAGE
<script>
var my_string = '';
function set_string( x ) { 
  my_string = x;
}
</script>

Then calling the function from the child page is simple:

CHILD PAGE
<script>
parent.set_string( "whatever" );
</script>

Answer 2

在弹出窗口中，您可以致电

window.opener.<your function>(<the xml>)
