Passing a reference to the popup window

[DIZZIEDAZZ]

Is there a way, I could pass the reference to a pop up window to
another function?

Basically, this is what I want to
var win= window.open("x.htm".....)

SetValue(win,"txtName");

//-------------------------------------------
function SetValue (win, ctlID)
{
var obj=win.getElementByID(ctlID);
ctlID.value="Hi";
}
I am getting errors when I do this. Any help is appreciated. Thanks

Of course there is.

Consider using a lowercase character for first character of the function
identifier. It helps to tell simple functions and those designed to serve
as constructors apart, and is thus considered a Good Thing regarding code
style.
{
var obj=win.getElementByID(ctlID);
ctlID.value="Hi";
`ctlID' is a string, not the object reference you tried to retrieve.
}

"Does not work" is a useless error description. [psf 4.11]
See <http://jibbering.com/faq/#FAQ4_43>.

getElementById() -- notice the case -- is a method of Document objects,
not of Window objects. Try

var obj = win.document.getElementById(ctlID);
if (obj && typeof obj.value != "undefined")
{
obj.value = "Hi";
}

for required feature tests (an example was given above).

However, since you are trying to assign something to the `value' property
in the process, I assume you are trying to modify the value of a form
control. You should not use getElementById() in that case as it requires
W3C DOM Level 2 Support and is probably slower than the alternative.

Consider making it a child element of a `form' element; this would allow
you to refer to the form control by

win.document.forms[...].elements[ctlID]

where `...' would either be the 0-based index or the name string of the
`form' element. Most of this referencing (after document) is specified
in W3C DOM Level 2 HTML, however it is also backwards compliant.
