I.E has problem with MouseEvents in some cases.

as a work around you could use something like below

var event = document.createEvent("MouseEvent");
event.initMouseEvent("click",false,false,window,0,0,0,0,0,false,false,false,false,0,null);

so your logic with fallback IE logic would be like below.

if (typeof MouseEvent !== 'function') {
    var event = document.createEvent("MouseEvent");
    event.initMouseEvent("click", false, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
} else {
    var event = new MouseEvent('click',{"bubbles":false, "cancelable":false});
}

  • @chetnagupta did you forget to put final function? I don't see anything code. – ngChaitanya May 15 '18 at 11:52
  • function saveFile (strData,filename) { var save_link = document.createElement('a'); save_link.href = strData; save_link.download = filename; if (typeof MouseEvent !== 'function') { var event = document.createEvent("MouseEvent"); event.initMouseEvent("click", false, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null); save_link.dispatchEvent(event); } else { var event = new MouseEvent('click',{"bubbles":false, "cancelable":false}); save_link.dispatchEvent(event); }} – Chetna Gupta May 15 '18 at 11:54
  • Looks like Canvas2ImageJS doesnt work in IE11 at all. i cant find any working demo in IE11 for the same. – Chetna Gupta May 15 '18 at 11:58
