javascript - Printing Popup Window after loading -

i've spent more 5 hours on this, i'm trying load link on popup window , after loading want print it.

so did following

<script src="http://code.jquery.com/jquery-latest.min.js"></script> <script>         function printer(){             var link = 'file:///c:\\page0339.swf';             w = window.open(link, "_blank", "location=1,scrollbars=1,menubar=1,width=600, height=400");             w.onload = function() {                  this.print();                 this.close();             };         }          $(document).ready(function () {              $("#print").click(function () {                 printer();             });          });  </script> <input type ="button" id = "print" value = 'print' /> 

inside onload i've tried alert message , shows both this.print();this.close(); never called, , didn't see javascript error. how can call print function inside onload??

seems attaching onload after opening window wrong way go. instead of

w.onload = function() {                  this.print();                 this.close();             }; 

have tried this?

w.print(); w.close();
