I have an iframe that includes a button:
<input type="button" value="close" onclick="window.close();" />

I'd like to detect the iframe close from the parent

<mathematics, data> The {ancestor} {node} in a {tree} that
	points to the current node (one of its child nodes).

window, I was
using this but every time the page loads the close event

1. <software> An occurrence or happening of significance to a
	task or program, such as the completion of an asynchronous
	input/output operation.  A task may wait for an event or any
	of a set of events or it may (request to) receive asynchronous
	notification (a {signal} or {interrupt}) that the event has
	occurred.

	See also {event-driven}.

	2. <data> A transaction or other activity that affects the
	records in a file.

fires!

function

1. <mathematics> (Or "map", "mapping") If D and C are sets
	(the domain and codomain) then a function f from D to C,
	normally written "f : D -> C" is a subset of D x C such that:

	1. For each d in D there exists some c in C such that (d,c) is
	an element of f.  I.e. the function is defined for every
	element of D.

	2. For each d in D, c1 and c2 in C, if both (d,c1) and (d,c2)
	are elements of f then c1 = c2.  I.e. the function is uniquely
	defined for every element of D.

	See also {image}, {inverse}, {partial function}.

	2. <programming> Computing usage derives from the mathematical
	term but is much less strict.  In programming (except in
	{functional programming}), a function may return different
	values each time it is called with the same argument values
	and may have {side effects}.

	A {procedure} is a function which returns no value but has
	only {side-effects}.  The {C} language, for example, has no
	procedures, only functions.  {ANSI C} even defines a {type},
	{void}, for the result of a function that has no result.

temp(){
alert('the iframe was closed');
}

function setup(){
var myIFrame = document.getElementById("iframe1");
if (myIFrame.addEventListener) {
myIFrame.addEventListener('onclose', temp(), false);
}else if (myIFrame.attachEvent) {
myIFrame.attachEvent ('onclose',temp);
}else{
myIFrame.onclose=temp();
}
}
window.onload=setup;

Any suggestions'd be appreciated.

TIA,
Mike

In {object-oriented programming} sending a message to an
	{object} (to invoke a {method}) is equivalent to calling a
	{procedure} in traditional programming languages, except that
	the actual code executed may only be selected at run time
	depending on the {class} of the object.  Thus, in response to
	the message "drawSelf", the method code invoked would be
	different if the target object were a circle or a square.

Would this function call: "temp()", on the line

1. <hardware> An electrical conductor.  For distances larger
	than a breadbox, a single line may consist of two electrical
	conductors in twisted, parallel, or concentric arrangement
	used to transport one logical signal.

	By extension, a (usually physical) medium such as an {optical
	fibre} which carries a signal.

containing this statement:
"myIFrame.addEventListener('onclose', temp(), false);" have anything to do
with it?

I do not know, I thought that was the proper way to attach an event
listener so that when myIFrame fired the onclose event the temp function
was called. Is that wrong?

You're supposed to pass a reference, not call the function. Delete the
brackets after the function name.

<artificial intelligence, information science> The objects,
	concepts and relationships that are assumed to exist in some
	area of interest.  A collection of {knowledge}, represented
	using some {knowledge representation} language is known as a
	{knowledge base} and a program for extending and/or querying a
	knowledge base is a {knowledge-based system}.

	Knowledge differs from {data} or {information} in that new
	knowledge may be created from existing knowledge using logical
	{inference}.  If information is data plus meaning then
	knowledge is information plus processing.

	A common form of knowledge, e.g. in a {Prolog} program, is a
	collection of {facts} and {rules} about some subject.

	For example, a {knowledge base} about a family might contain
	the facts that John is David's son and Tom is John's son and
	the rule that the son of someone's son is their grandson.
	From this knowledge it could infer the new fact that Tom is
	David's grandson.

	See also {Knowledge Level}.

the correct way to handle

1. <programming, operating system> A simple item of data that
	identifies a resource.  For example, a {Unix} file handle
	identifies an open file and associated data such as whether it
	was opened for read or write and the current read/write
	position.  On the {Macintosh}, a handle is a pointer to a
	pointer to some dynamically-allocated memory.  The extra level
	of indirection allows on-the-fly {memory compaction} or
	{garbage collection} without invalidating application program
	references to the allocated memory.

	2. <jargon> An alias used intended to conceal a user's true
	identity in an electronic message.  The term is common on
	Citizen's Band and other amateur radio but, in that context
	usually means the user's real name as {FCC} rules forbid
	concealing one's identity.

	Use of grandiose handles is characteristic of {crackers},
	{weenies}, {spods}, and other lower forms of network life;
	true hackers travel on their own reputations.

	Compare {nick}.

this in mozilla'd
be

myIFrame.addEventListener('close', temp, false);

Hi,

Just a short correction: myIFrame.addEventListener belongs to NS/
Firefox. Some of the events for NS/Firefox don=B4t contain the prefix
'on' lika onload, onblur etc. For NS/Firefox you gotta define the
event as 'load' or 'unload'

So per my knowledge the correct way to handle this in mozilla'd
be

myIFrame.addEventListener('close', temp, false);

Regards
