html2canvas code not working IE 11

Question

I am hoping to use the html2canvas library to make a image of one div and put it in another. So far I have it working wonderfully in Safari, Chrome, and Firefox but not IE (11 is the only version I care about right now).

I am applying it using the code from this jsfiddle from another Stackoverflow question:

var aaaDiv=document.getElementById('aaa');
var ttDiv=document.getElementById('tt');

html2canvas(aaaDiv).then(function(canvas) {
// assign id:avatarCanvas to canvas 
canvas.id='avatarCanvas';
// append canvas to ttDiv
ttDiv.appendChild(canvas);

});

I heard IE doesn't like to 'appendChild', but I am not sure how to proceed from there.

Answer 1

The appendChild function has nothing to do with the issue you're facing. appendChild has been supported ever since IE6+

By looking at the html2canvas code, the library happens to make use of the Promises feature which unfortunately is not being supported in any version of IE

(though it is supported in Microsoft Edge)
