javascript - how to detect window.print() finish -

in application, tried print out voucher page user, used:

  var htm ="<div>voucher details</div>";   $('#divprint').html(htm);   window.settimeout('window.print()',2000); 

'divprint' div in page store information voucher.

it works, , print page pops up. want further proceed application once user click 'print' or 'close' pop window.

for example, i'd redirect user page after pop window closed:

window.application.directtoantherpage();//a function direct user other page 

how determine pop print window closed or print finished?

in firefox , internet explorer can listen after print event.

https://developer.mozilla.org/en-us/docs/web/api/window.onafterprint

window.onafterprint = function(){    console.log("printing completed..."); } 

it may possible use window.matchmedia functiionality in other browsers.

(function() {      var beforeprint = function() {         console.log('functionality run before printing.');     };      var afterprint = function() {         console.log('functionality run after printing');     };      if (window.matchmedia) {         var mediaquerylist = window.matchmedia('print');         mediaquerylist.addlistener(function(mql) {             if (mql.matches) {                 beforeprint();             } else {                 afterprint();             }         });     }      window.onbeforeprint = beforeprint;     window.onafterprint = afterprint;  }());
