Question

Update asp:listbox in window.opener page

Asked by: jayh99

I am trying to add a new item to an asp listbox using javascript from a child window.  I have tried the following code on my child page without any luck:

var to = window.opener.document.getElementById("Recipient");
     to.options.add(new Option('1','1'));


I have also tried:
var to = parent.document.getElementById("Recipient");
without any luck also.

The following code works fine on the parent page to add new items to the listbox:
   
function AddItem(){
    var to = document.getElementById("Recipient");    
     to.options.add(new Option('1','1'));
     }

Any help is greatly appreciated.

try

alert(window.opener)

and verify that it doesn't say "null" if it does there's something wrong with how you're accessing the child window.

[object]

 

by: jayh99Posted on 2008-09-29 at 12:30:08ID: 22599754

alert(window.opener.document.getElementById("Recipient"));

also returns [object]

 

by: CyrexCore2kPosted on 2008-09-29 at 12:31:17ID: 22599771

what about

alert(window.opener.document.getElementById("Recipient").options);

?

 

by: jayh99Posted on 2008-09-29 at 12:32:40ID: 22599790

The javascript error returned when I run the script mentioned in my question is:

"Error: Unspecified error."

Not too useful...  :-)

 

by: jayh99Posted on 2008-09-29 at 12:33:43ID: 22599803

That returns [object] as well.

 

by: CyrexCore2kPosted on 2008-09-29 at 12:35:10ID: 22599816

Okay well that seems all well and good. What aboutttt

var opt = new Option('1', '1');
alert(opt);

?

 

by: jayh99Posted on 2008-09-29 at 12:36:15ID: 22599825

[object] as well.

 

by: CyrexCore2kPosted on 2008-09-29 at 12:37:53ID: 22599845

And this still results in an error?

var opt = new Option('1', '1');
window.opener.document.getElementById("Recipient").options.add(opt);

 

by: jayh99Posted on 2008-09-29 at 12:39:14ID: 22599862

Yep, still the "Unspecified Error" in the javascript.

 

by: CyrexCore2kPosted on 2008-09-29 at 12:39:23ID: 22599869

If that doesn't work try this. Add this function to the child page:

function AddItem(opt){
    var to = document.getElementById("Recipient");    
     to.options.add(opt);
}

And then on the main page try this:

window.opener.AddItem(opt);

 

by: CyrexCore2kPosted on 2008-09-29 at 12:39:38ID: 22599873

err, obviously define opt first in the main page.

 

by: jayh99Posted on 2008-09-29 at 12:42:46ID: 22599905

Now I receive the "Unspecified error" on the parent page when AddItem is called.

 

by: jayh99Posted on 2008-09-29 at 12:52:03ID: 22599981

Very weird, but I got this working:

On Parent Page:

   function AddItem(Recipient){
   alert(Recipient);
   var to = document.getElementById("Recipient");    
   to.options.add(new Option(Recipient,Recipient));
    }

On Child Page

   function addRecipient(RecipientName){              
   window.opener.AddItem(RecipientName);
   }

Thanks for the help with this!
