Can I combine document.form.submit with window.open?

[crunch42]

I have a form with two submit buttons. One button works like a regular submit button and inserts a new record in a db. The second is a "preview" button. What I'd like to do when the Preview button is clicked is have the form contents posted into a popup window. Is this possible?

My current code:

<script type="text/javascript">
function submitFunction(i) {
   if (i==1) document.form.action=
      "preview.php";
   if (i==2) document.form.action=
      "insertrecord.php";
   document.form.submit()
   }</script>

<input type="submit" name="Preview" value="Preview" onClick="submitFunction(1)">           
<input type="submit" name="Publish" value="Publish" onClick="submitFunction(2)"> 

So basically I want to combine the existing document.form.submit with something like a window.open, or any other way to open a popup window. Any ideas?

Thanks,
Julian

In case it helps anyone else:

<script type="text/javascript">
function submitFunction(i) {
   if (i==1) { document.form.action= "preview.php";
      document.form.target = '_new';
      document.form.submit() }

   if (i==2) { document.form.action="insertrecord.php";
      document.form.submit() }
   }
</script>
<input type="submit" name="Preview" value="Preview" onClick="submitFunction(1)">           
<input type="submit" name="Publish" value="Publish" onClick="submitFunction(2)">
