JavaScript open in a new window, not tab

Specify window "features" to the open call:

window.open(url, windowName, "height=200,width=200");

When you specify a width/height, it will open it in a new window instead of a tab.

See https://developer.mozilla.org/en-US/docs/Web/API/Window.open#Position_and_size_features for all the possible features.

You don't need to use height, just make sure you use _blank, Without it, it opens in a new tab.

For a empty window:

window.open('', '_blank', 'toolbar=0,location=0,menubar=0');

For a specific URL:

window.open('http://www.google.com', '_blank', 'toolbar=0,location=0,menubar=0');

I may be wrong, but from what I understand, this is controlled by the user's browser preferences, and I do not believe that this can be overridden.

Try:

window.open("", [window name], "height=XXX,width=XXX,modal=yes,alwaysRaised=yes");

I have some code that does what your say, but there is a lot of parameters in it. I think these are the bare minimum, let me know if it doesn't work, I'll post the rest.

You might try following function:

<script type="text/javascript">
function open(url)
{
  var popup = window.open(url, "_blank", "width=200, height=200") ;
  popup.location = URL;
}
</script>

The HTML code for execution:

<a href="#" onclick="open('http://www.google.com')">google search</a>

You shouldn't need to. Allow the user to have whatever preferences they want.

Firefox does that by default because opening a page in a new window is annoying and a page should never be allowed to do so if that is not what is desired by the user. (Firefox does allow you to open tabs in a new window if you set it that way).

For me the solution was to have

"location=0"

in the 3rd parameter. Tested on latest FF/Chrome and an old version of IE11

Full method call I use is below (As I like to use a variable width):

window.open(url, "window" + id, 'toolbar=0,location=0,scrollbars=1,statusbar=1,menubar=0,resizable=1,width=' + width + ',height=800,left=100,top=50');
