Checking for element...

[jodleren]

Hi

In a popup window (by a button) I use this to pass data on to the
parent window:

window.opener.document.forms[0].receivers.value=sellist;

I have tried to check for the receiveres element, type=text, but... so
far without luck.... how can I do that?

/S

What exactly do you want to check? Whether that particular control is of
type text?
if (window.opener && ! window.opener.closed) {
var control = window.opener.document.forms[0].receivers;
if (control && control.type == 'text') {
...
}
}

In case the user has clicked away on the opener window. Then there
might be a form etc, but not the one which I just had.
I wonder whether I should check for the form name too.

Yes, do that.

It would be better if you stored a reference to the form object when the
popup is opened and on access compare whether or not the collection item
and the previously stored reference are identical. With names, there is
no guarantee; anybody may use the same names as you do. With object
references, there is the guarantee that two separate objects themselves
are never the same; they have identity.
