Parent/Child form interaction
Someone recently posted a question about having a child form that could update values in a parent form. So I started toying around with the idea.
I have a form that includes a link that will open a popup with an identical form; any changes done to the child form are reflected in the parent form.
I'm trying to do vice-versa, and am hitting a wall.
I'm setting a variable to a function that spawns the popup, but that variable is "undefined" when I try to access it.
var childForm = messageWindow(args); (messageWindow is the function and it's too much code to type, here.)
So.. how does one reference a child window in JS?
