window.open does not work?

[Edwin Boersma]

Hi,

I've just installed Netscape 7.1 for Linux and the following script
refuses to open a window when I call this function:

function OpenLinkWindow( ) {

wMap=window.ope n('http://naxos.orangepor t.net/cyclades-info/ShowMap.php?id_ advert=45&map=' ,'','width=400, height=600');
wMap.onResize =
'self.location. href=http://naxos.orangepor t.net/cyclades-info/ShowMap.php?id_ advert=45&map='
wMap.focus();
self.close();
}

In other browsers (NS 7.0/Win98, IE6/Win98) and in Netscape 7.0 for
Linux, it works fine.

What has changed in 7.1?????


Rgds,
Edwin

One of the top most frequent validation errors is to forget to escape
ampersands in url strings.

B.2.2 Ampersands in URI attribute values

http://www.w3.org/TR/html401/appendix/notes.html#h-B.2.2

Common Validation Problems:
Ampersands (&'s) in URLs

http://www.htmlhelp.org/tools/validator/problems.html#amp

height=600 will overflow the availHeight value on most scr. res.
(800x600, even 1024x768 ones) and will therefore trigger error
correction mechanisms to adjust the window size. Cpu, time, RAM will
unneedlessly be involved to reduce this 600px height to something shorter.
As coded, the window will not be resizable, will not have scrollbars if
he content overflows the actual, real window dimensions and will not
have status bar. Preventing resizing the window and removing scrollbars
when they are needed is counter-accessibility and anti-usability: they
both go against the best and most objective interests of the user and
the author; therefore this can not be recommendable.

Not an event handler at all here. No function call; just an url.

Illogical.

A window not opened by javascript can NOT be closed by javascript. So
the opener here must have been opened by javascript otherwise this
instruction will not be honored in NS 7.1 and will generate a security
warning in the javascript console.

<script type="text/javascript">

function OpenLinkWindow( )
{
if(WindowObject Reference == null || WindowObjectRef erence.closed)

}
else

I doubt very much it "works fine" in any browser. Events are all lower case in JavaScript, so wMap.onResize is simply
creating a new property and assigning your string value to it.

Even if you wrote:

wMap.onresize = 'whatever';

you're still assigning a string to the event, and you need to be assigning a function.

Maybe you meant:

wMap.onresize = function() {
self.location.h ref =
'http://naxos.orangepor t.net/cyclades-info/ShowMap.php?id_ advert=45&map=' ;
}

?

However, even assuming you got the syntax for assigning the onresize event correct, there's still the matter that you are
potentially assigning wMap.onresize before it's content has even finished loading, at which point the <body ...
onresize="..."> event (if any) would overwrite your assignment. If there is no onresize event for the content you are
loading, then most likely your carefully crafted onresize event is simply being replaced by null.

If any of what you had above was working in any browser, then it was a bug in /that/ browser, not the current one.

Exactly.

<body onresize="..."> is not HTML 4 valid anyway. AFAIK, only the
document and the window objects can have a resize event listener.

The OP's code is still nebulous, counter-productive and confusing. If an
resize event is triggered, then he wants to load the resource in the
opener, give focus to the popup and then close the opener.
