關(guān)鍵點(diǎn)：

img.src = URL.createObjectURL(file.files[0]);

準(zhǔn)備一個(gè) #file?input[type=file]

var fImg = document.getElementById('file');

fImg.onchange = function(){

var tb = document.querySelector('#tblQRResult');

for(var i = 0 , l = this.files.length;i<l;i++){

addImage(tb,this.files[i]);

}

}

function addImage(tb,imgFile){

var tr = document.createElement('tr'),

td1 = document.createElement('td'),

td2 = document.createElement('td'),

td3 = document.createElement('td'),

img = document.createElement('img'),

s = URL.createObjectURL(imgFile);

img.src = s;

// img.style.height = '120px'

td1.appendChild(img);

tr.appendChild(td1);

tr.appendChild(td2);

tr.appendChild(td3);

tb.appendChild(tr);
