you need reuse window's name. in example, you've named window "formtarget".

you can this, example:

var popupwin = null; var mainvar = {     setformsubmit: function() {        popupwin = window.open('', 'formtarget','width=650, height=800');     } }  function openanotherlink(url) {      popupwin.location.href = url; }
