Passing data from parent to child window

[sarahnice]

Hi,
I have a html page with a standard form on it. The form contains some hidden fields and some visible data. None of the data on this page is editable. When the user click on an link beside a particular field, a child window opens. I would like to know how to retrieve the data in the hidden field of the parent window and display them in the text fields of the child window.

Any help would be greatly appreciated
Thank you

First of all the domain of the child and parent have to be the same. you cannot run javascript acros domains.

In the child window (popup window):
window.opener.document.getElementById('id of the hidden box').value

In the parent window:
objWindow = window.open(...
objWindow.document.getElementById('id as string' + intCounter).value

In the parent window example I used intCounter, with getElementById you pass the id as string. If you have a lot of hidden boxes all named hid1, hid2, hid3, hid4... you can loop through them.

you can also use the

window.showModalDialog

and

window.showModelessDialog

functions to open your child window as they accept openning arguments than can be retrieved in child window by

window.dialogArguments

method. My advice : concatenate all your parameters separating them with pipes (|) or other non usual chars before opening and then use split in child to get them. Water is not bad as long as it stays out human body ;-)
