<p>Is there a way to make a popup window maximised as soon as it is opened? If not that, at least make it screen-sized? This:</p>

<pre><code>window.open(src, 'newWin', 'fullscreen="yes"')
</code></pre>

<p>apparently only worked for old version of IE.</p>

Use
```
screen.availWidth
```
and
```
screen.availHeight
```
to calculate a suitable size for the height and width parameters in
```
window.open()
```
Although this is likely to be close, it will not be maximised, nor accurate for everyone, especially if all the toolbars are shown.
