[Solved] Pass Uploaded Image in document.getElementById instead of canvas


I edited that two files

1. Javascript code

var target;
const imageUrl = "";

var jsonData = {
    "layers": [{
        "x": 0,
        "height": 200,
        "layers": [{
                "type": "image",
                "name": "bg_img",
                "x": 0,
                "y": 0,
                "width": 200,
                "height": 200,
                "src": "14IVyVb.png",
            },
            {
                "type": "image",
                "src": "l8vA9bB.png",

                "x": 10,
                "y": 15,
                "width": 180,
                "height": 166
            }
        ],
        "y": 0,
        "width": 200
    }]
};

const containerElement = $('#container');
const fileUp = $('#fileup');
let mask;
let file;

$(function() {

    // Upload image onclick mask image

    containerElement.click(function(e) {
        var res = e.target;
        target = res.id;
        if (e.target.getContext) {
            // click only inside Non Transparent part 
            var pixel = e.target.getContext('2d').getImageData(e.offsetX, e.offsetY, 1, 1).data;
