Trasferring value from one to one window

eapsokha · February 21st, 2004, 02:03 AM

Suppose a user click a link from one windows to load another form in a popup window. When he applies OK then the a field of the first window will retrieve the input from the second form without lossing the current value. How can I do that? I am sorry if my question is complicated.

Many thanks

You can do it with JavaScript or VBScript (only in IE) in the browser envoriment.

I am poor with Javascript. So could you show me the sample code?

What value?

This should work in all browsers except NN 2 and before:

Code:

opener.document.forms["userData"].age.value = document.forms["entry"].userAge.value;

What happens?
All browsers assign an opener property to a window created via the window.open() method. In my example the <form> in the second window is userData, with the text field age and the first <form> is entry with the text field userAge. This script should reside in the subwindow. The opener property is not assign if opened by the user (then it's NULL). You can check for that by using this code snippet:

Code:

if (typeof window.opener == "object"){
  // current subwindow opened by script
}

Happy programming (like their say on 4guysfromrolla). :)

The last snippet would look something like this in VBScript:

Code:

If (IsObject(window.opener)) Then
  // current subwindow opened by script
End If
