Opening new window in HTML for target="_blank"

<a href="facebook.com/sharer" target="_blank" >Share this</a>

How do I make this a certain width and height, in a new window, when the user clicks on it? In firefox, the开发者_如何学运维 current code only opens up a new tab (not a new window)

To open in a new windows with dimensions and everything, you will need to call a JavaScript function, as target="_blank" won't let you adjust sizes. An example would be:

<a href="http://www.facebook.com/sharer" onclick="window.open(this.href, 'mywin',
'left=20,top=20,width=500,height=500,toolbar=1,resizable=0'); return false;" >Share this</a>

Hope this helps you.

You can't influence neither type (tab/window) nor dimensions that way. You'll have to use JavaScript's window.open() for that.

You don't have that kind of control with a bare a tag. But you can hook up the tag's onclick handler to call window.open(...) with the right parameters. See here for examples: https://developer.mozilla.org/En/DOM/Window.open

I still don't think you can force window over tab directly though-- that depends on the browser and the user's settings.
