javascript - window.matchMedia('print') failing in Firefox and IE -


i have print button launches print functionality on webpage. button hides user clicks on , shows if user done printing or presses close in print window. works fine in chrome failing in firefox , ie.

<input type="button" onclick="launchprint()" value= "print me" />   function launchprint(){ $(".print-box").hide(); window.print(); }  (function() {     if (window.matchmedia) {         var mediaquerylist = window.matchmedia('print');         mediaquerylist.addlistener(function(mql) {             if (!mql.matches) {                 $(".print-box").show();             }         });     } }()); 

any suggestions may missing?

unfortunately, on same problem , did research. seems bug exists on recents version of ff , ie still , hasn't been fixed.

you can check out bug firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=774398

i found person having same issue , hasn't satisfying answer: https://social.technet.microsoft.com/forums/office/en-us/bc3ca05e-b4ef-425b-8bbd-d3f700a8c85e/windowmatchmedia-not-firing-for-print-in-ie?forum=ieitprocurrentver

if ever come accross solution, edit this.

i use same code exemple highchart resize before printing:

function printupdate() {     jquery.each(highcharts.charts, function(index, value){         value.reflow();     }); }; var mediaquerylist = window.matchmedia('print'); if(navigator.appversion.indexof("msie 8.")!==-1)//for ie8 {     document.attachevent(function (mql){printupdate();}, mediaquerylist); } else {     if (window.matchmedia) {         mediaquerylist.addlistener(function (mql) {             if (mql.matches)             {                 printupdate();             }         });     } }  window.onbeforeprint = printupdate; 

this work fine in chrome. ff , ie11 won't fire event.
