I want to reload a url in a browser window so I do something like this:
open(window.loc ation.href= "www.yahoo.com" );
ok, so now I want to do something when that page is done loading
completely. how do I do this?
What I have tried is this:
a=open(window.l ocation.href= "www.yahoo.com" );
a.onload=b();
function b(){
alert("Done!!") ;
}
but none of this works. I am only concerned with IE.
Any advice on how I can get this to work?
My goal, if not clear from above, is to load some arbitrary page in a
window and then do <something else>, function b(), only when that page
is completely done loading.

In IE, use the onreadystatecha nge event handler in the Body:
<body onreadystatecha nge="if(this.re adyState=='load ed'){....}"> however,
onload= works the same way.

No, you didn't understand. I have no control over the content of the
child window. If I did I would have used onload or whatever you
suggested already.
How do I tell when a child window is done loading? WHEN I HAVE NO
CONTROL OVER THE CONTENT OF THE CHILD WINDOW.

What I have tried is this:
a=open(window.l ocation.href= "www.yahoo.com" );
Two mistakes: the window.open() method takes three parameters, all optional,
all strings, but you have a script statement there. The first parameter is
the url to open, either relative to the current page, or absolute, in which
case the protocol, usually http:,is required; the second and third specify
the name and features such as bars and sizes.
What you pass as the parameter here, is the returnvalue of the Javascript
statement window.location .href=etc. This happens to be the string that
contains the url, but the protocol is missing so it is interpreted
relatively.
What you are looking for is something like this:
window.open( "http://www.yahoo.com" );
a.onload=b();
One: When assigning a function to an event handler, you don't necessarily
want to execute that function. Drop the brackets () and you 're fine.
However: this will never work cross-domain. Browser built-in security
measures prevent JavaScript from accessing pages that are not from the same
domain. Only when you open a window with a page from your own site, can you
attach onload event handlers and other stuff. For more on this, try

ok, I am reporting back to say that that faq has nothing to do with
checking the status of a child window. Thanks for not even bothering to
read my question.
after a few hours of misery I got this
var windowReference =
open(external.m enuArguments.lo cation.href=doc .URL);
while(windowRef erence.document .readyState!="c omplete"){}
<do-something>
Which simply creates the child window and then loops until it is done
loading. This works for what I want.
Not sure why this took so long. seems like I had to run through quite a
few permutatins of window rewferences and different attempts at
ascertaining some sort of status of the child window.

You realise that if you busy wait like this for too long, there's a fair
chance that the client's web browser will decide that the script's crashed
and nuke it? This may be triggered by, for example, a slow 'net connection.

You're probably running afoul of the security rules --- there isn't much you
can do with a frame or window containing a page belonging to a different
domain.
BTW: you might get more people willing to help if you didn't shout so much.
Some of your other messages are definitely a bit on the rude side.

This newsgroups is all but dead. I wouldn't shout if there was anybody
here with a clue. Mostly just a bunch of stupid assed curries begging
for someone to do their work for them.
Anyway, I ended up solving my own problem so posting here was just a
waste of time.

Well who am I to expect or even hope for the tiniest bit of thanks for
trying to be helpful, warning for potential oversights and other forms of
narrowmindednes s, and various similarly carefully chosen words. I have seen
quite a few newsgroups, and the discussions on this particular one happen to
be among the friendliest and most intelligent around imho (which perhaps
sais more about the other groups, but never mind that). Only generally
speaking, of course.
Here 's to a happy life, jaialai!
