Determine If Print/Cancel Button in Google Chrome's Print Preview is Clicked

Question

I've been printing my page using the code below:

window.print();

An image below is what the print preview in Google chrome browser looks like. It has two main buttons: print and cancel.

I want to know if the user has clicked the print or cancel buttons. What I did uses jquery:

HTML Code of the Print Preview:

<button class="print default" i18n-content="printButton">Print</button>
<button class="cancel" i18n-content="cancel">Cancel</button>

Jquery Code:

 $('button > .cancel').click(function (e) {                
      alert('Cancel');
 });

 $('button > .print').click(function (e) {                
      alert('Print');
 });

I tried the code above with no luck. What am I missing?

You can not access Chrome's internal windows (printing dialog in this case) directly from a regular web page.

    (function () {

        var beforePrint = function () {
            alert('Functionality to run before printing.');
        };

        var afterPrint = function () {
            alert('Functionality to run after printing');
        };

        if (window.matchMedia) {
            var mediaQueryList = window.matchMedia('print');

            mediaQueryList.addListener(function (mql) {
                //alert($(mediaQueryList).html());
                if (mql.matches) {
                    beforePrint();
                } else {
                    afterPrint();
                }
            });
        }

        window.onbeforeprint = beforePrint;
        window.onafterprint = afterPrint;

    }());

Or, If you want to do something when the print preview gets opened, you can try below:

$(document).bind("keyup keydown", function (e) {
         if (e.ctrlKey && e.keyCode == 80) {
             setTimeout(function () { CallAfterWindowLoad();}, 5000);
             return true;
         }
     });

    function CallAfterWindowLoad()
    {
        alert("Open and call");
    }

Maybe if you provide your requirements for this two buttons click event, we can provide you an alternate solution.
