How do I submit forms to a new window, with window.open() features?

Many people have asked how they can submit a form to a new window. This is fairly trivial to accomplish; you can just set up your form tag like this: 
 

<form      target=_blank      action=whatever.asp>

 
However, some would like to submit their forms to a new window that they have a little more control over. 
 
This is not really an ASP issue, as the solution could be used in any web-based technology (including plain HTML). However, here is a way to submit a form to a new window, and have control over parameters like width, height, toolbar, etc.: 
 

<form name=form1      method=post      action=whatever.asp      target=myNewWin>        <input type=hidden name=foo value='bar'>        <input type=button          value=' Submit '          onClick='sendme();'>  </form>    <script>  function sendme()  {      window.open("","myNewWin","width=500,height=300,toolbar=0");      var a = window.setTimeout("document.form1.submit();",500);  }  </script>
