Write CheckBox's back to opening window

Kai

Hi guys,

I need some help on a Javascript. I have a page that opens a popup windowwhich you can select some checkboxes. When you click Submit on the popup window i want to write the Values of the selected Checkboxes back to the Parent window into a Textbox.

Anyone have any ideas as my Javascript skills are badly lacking.

Does Javascript even allow you to change domain contexts like that? I thought everything was native to its own DOM...

You'll need two things:

First you'll need 'window.opener' to pass the values back from the popup window to its parent.

Secondly you'll need to explicitly check the 'selected' status of each checkbox, rather than just dumping the values back.

However, using this method, there are some serious usability and accessability concerns, so I'd think twice about the way you're going about this (or at least the way it sounds like you're going about it).

Any probs, pop up some sample code and we'll take a look.

doodle_sketch - you can only do this when it's a popup window and when that window comes from the same site (i.e. same domain) as the parent.

Well i was hoping to Draw the Checkboxes dynamically from a DB and then the ones that are selected get written back to a Text box on the Parent window with a script something like :

function PassandClear(obj){
alert(document.form1.chkAgent.value);
self.opener.document.frmSearch.txtAgents.value = obj.chkAgent.value;
//self.close;
}

The problem is it doesnt work, The Text box on the Parent window shows Undefined. I think the problem is that javascript obviously doesnt handle Checkbox collections the same as ASP.

So can someone show me how to loop thru each one and write it back ?

Ok, to iterate through the list of checkboxes in a form is reasonably straightforward, but if your PassandClear function isn't working lets look at that first and resolve the problem there.

However, unfortunately it's not very clear from your snippit if everything is going to the right places and what's happening when the form is submitted.

For example what's passed into the 'obj' variable?

Is there any way you can post or link to trimmed versions of the two HTML files and the javascript you're using?

Tis alright thanks for the Help, i decided to not use a popup and just have it go to a new window.

Thanks anyway.
