open new window using Javascript.

[TJhood]

Please help!
Does anyone know how to add an attribute target to open up a new window in cascade menu javascript?
here is the script

<script type="text/javascript">
<!--
   function InitMenu()
   {
     var bar = menuBar.children     

     for(var i=0;i < bar.length;i++)

          menu.style.visibility = "hidden"
          bar[i].onmouseover = new Function("ShowMenu("+bar[i].id+")")
          var Items = menu.children
          for(var j=0; j<Items.length; j++)
            {
