how do I insert html into a window? This doesn’t seem to work:

var testwindow = window.open ("", “mywindow”,  
“height=800,width=400,location=no,scrollbars=yes”);  
var el = testwindow.document.createElement(‘div’);  
el.innerHTML = content;

1. this is a Rails mailing list – find a JavaScript list for this

2. “doesn’t seem to work” –

1. creating an element doesn’t insert it into the DOM
