open new pop up

[questions]

Is this older code still correct for a pop-up?
I have "resize=no" down but it's letting me resize it.

I'm not an expert. I copied this from somewhere long ago.

<script type="text/javascript">
<!--
function OpenBrWindow(theURL,winName,features, myWidth, myHeight, isCenter) { //v3.0
  if(window.screen)if(isCenter)if(isCenter=="true"){
    var myLeft =  (screen.width-myWidth-50)/2;
    var myTop = (screen.height-myHeight-50)/2;
    features+=(features!='')?',':'';
    features+=',left='+myLeft+',top='+myTop;
  }
  window.open(theURL,winName,features+((features!='')?',':'')+'width='+myWidth+',height='+myHeight);
}

//-->
</script>

<a href="#" onClick="OpenBrWindow('pop.html','','toolbar=no, location=no, status=no, menubar=no, scrollbars=yes, resizable=no','634','658','true');">Pop Up.</a>

THANKS.

The proper specification for a new window that cannot be resized is:

resizable=0

Or, just omit resizable from the specification. However, many browsers will no longer allow a new window that isn't resizable. It's an accessibility issue.

THANKS!

Does the rest of it look correct?
Should all the "no" be "0"?

Should all the "no" be "0"?

The rest should be fine with "no".

[questions]

And yes, you are right, I cannot control the resize, even with 0, it still let's you resize.

Thanks.

Yeah I'm pretty sure Firefox doesn't let you control the "resize" attribute, but IE might. I'm not sure.

I think this is a bug on FF3, can't test on FF2 if this problem is reproducible. Tested with a simple call and resizable seems to take no effect:

<a href="#" onclick='window.open("http://www.google.com/",
"mywin", "width=500,height=300,menubar=no,location=no,resizable=no,scrollbars=no,status=no");return false;'>Test</a>

Or maybe it is intended by Firefox. If the user can control the "resize" attribute, users may get annoyed by it. A website shouldn't be dependent on whether the window can resize or not.

Yeah, on FF3. It's fine if someone resizes. I think they'd only do it by mistake. I'm just trying to pop up a detail of a webpage or a zoom into an image.

In the specification section of the window.open() method, no and 0 are equivalent. In fact, if you specify any valid specification in the specification section of window.open, anything that you omit is considered as 0/no or default.

So let's break it down. You can do:

window.open('some.htm');

That's at the discretion of the browser, but at the very least should be a new tab, unless the page has a base href of '_self', or all pop ups are blocked.

Now:

window.open('some.htm', '_blank');

we've designated a target. What you designate has consequences. With '_blank', it should be a unique new window, not a tab unless browser settings override that.

Finally, we may add specifications:

window.open('some.htm', '_blank', 'width=400, height=350');

The moment you add any specification, the browser almost has to open a new window. And all specifications not mentioned will be either 0/no/false, or if they don't qualify as boolean (true/false), they will be the default for that browser. And, as I was saying, some browsers will not allow false for things like:

status
scrollbars
resizable

If you don't have any specifications, a window.open method will usually open a normal window, or tab. If you have specifications, they will be followed first as far as the rules governing specifications go, then ultimately as far as the user's browser will allow.

That's not to mention pop up blockers, which if set to their highest setting will block all new windows. It is because of this last fact that folks often prefer AJAX and/or lightbox type scripts. Those are generally only 'blocked' if the user has javascript disabled.
