addEventListener does not work in IE 11

January 28, 2021 by admin

I am using javascript to open a popup and execute some code once it is loaded.

This is the code:

// Öffnen des Print Popups binden.
$('#revi_print').unbind();
$('#revi_print').click(function() {

    // Popup erstellen.
    popup = window.open('report_handle/print.php?filter_report=' + $('#revi').data('filter_report'), "Popup", "width=1024, height=768, scrollbars=yes, toolbar=no, status=no, resizable=yes, menubar=no, location=no, directories=no, top=10, left=10");

    // Code erst ausführen, wenn das Popup geladen ist.
    popup.addEventListener('load', handle_popup, false);
});

It does work fine in Firefox and Google Chrome, however I have realized, that it does not work in the newest Internet Explorer.

From what I have read, addEventListener should be supported above IE9, so theoretically IE 11 should support it – however it seems this is not the case.

This error indicates, that IE11 is not supporting the method…

Is there a simple workaround to make this work?

I have just tried this pice of code:

if (popup.addEventListener){
    alert("firefox, chorome, etc");
    popup.addEventListener('load', handle_popup, false); 
} else if (popup.attachEvent){
    alert("IE");
    popup.attachEvent('load', handle_popup);
}

Apparently this should work according to different other threads, but it is not the case. The browser does go to the else if, when IE is used – however it still refuses to work.

Could it be, that attachEvent in IE does not work on popups?

I have just tried the method indicated in the first answer.

It works in firefox and chrome, but IE refuses to work, even tough this method does not have the EventListener any more:

// Öffnen des Print Popups binden.
$('#revi_print').unbind();
$('#revi_print').click(function() {

    // Popup erstellen.
    popup = window.open('report_handle/print.php?filter_report=' + $('#revi').data('filter_report'), "Popup", "width=1024, height=768, scrollbars=yes, toolbar=no, status=no, resizable=yes, menubar=no, location=no, directories=no, top=10, left=10");

    // Code erst ausführen, wenn das Popup geladen ist.
    //popup.addEventListener('load', handle_popup, true);

    popup.window.onload=function() { parent.handle_popup(popup); }
});

// Code zum handeln des Popups.
function handle_popup(popup) {
    var selected_report = $('#revi').data('filter_report');
    var jqplot_object = $('#revi_filter_ddReport_' + selected_report + '_jqplot_object').html();
    var has_chart = $('#revi_filter_ddReport_' + selected_report + '_has_chart').html();
    var obj = $.parseJSON($('#revi').data('data').trim());

    // Den Kontent kopieren.
    popup.$('#revi_sec_report_container').html($('#revi_report_container').html());

    // Den Print Button entfernen.
    popup.$('#revi_print').remove();

    // Das chart entfernen.
    popup.$('#revi_chart').empty();

    // Wenn ein Chart gezeichnet werden soll.
    if (has_chart == 1) { 
        var execute_string = $.base64.decode(jqplot_object);
        eval(execute_string); 
    }
}

Next attempt (half successful):

I have added this line of code to the HTML of the POPUP:

This are the changes on the javascript side:

// Öffnen des Print Popups binden.
$('#revi_print').unbind();
$('#revi_print').click(function() {

    // Popup erstellen.
    popup = window.open('report_handle/print.php?filter_report=' + $('#revi').data('filter_report'), "Popup", "width=1024, height=768, scrollbars=yes, toolbar=no, status=no, resizable=yes, menubar=no, location=no, directories=no, top=10, left=10");

    $('body').data('the_popup', popup);

    // Code erst ausführen, wenn das Popup geladen ist.
    //popup.addEventListener('load', handle_popup, true);

    //window.onload=function() { handle_popup(popup); }
});

// Code zum handeln des Popups.
function handle_popup() {

    var popup = $('body').data('the_popup');

    var selected_report = $('#revi').data('filter_report');
    var jqplot_object = $('#revi_filter_ddReport_' + selected_report + '_jqplot_object').html();
    var has_chart = $('#revi_filter_ddReport_' + selected_report + '_has_chart').html();
    var obj = $.parseJSON($('#revi').data('data').trim());

    // Den Kontent kopieren.
    popup.$('#revi_sec_report_container').html($('#revi_report_container').html());

    // Den Print Button entfernen.
    popup.$('#revi_print').remove();

    // Das chart entfernen.
    popup.$('#revi_chart').empty();

    // Wenn ein Chart gezeichnet werden soll.
    if (has_chart == 1) { 
        var execute_string = $.base64.decode(jqplot_object);
        eval(execute_string); 
    }
}

On firefox and Chrome it works perfectly, the popup opens, and the chart that should be drawn on the popup shows up.

Now IE also executes the code for the popup, which is very good, but now only for IE JQPLOT does throw an error somewhere in the library.

I have no clue why this happens, I can only guess that the popup is not jet finished loading, when the code for jqplot is executed.

Got everything working now – the jqplot thing is fixed now…
