在Javascript裡,我們可以使用html2canvas來將網頁畫面的某個區塊截圖下來存檔。

運用方式如下:
HTML

<div id="container">
Hello world!
</div>

JavaScript
  $('html, body').scrollTop(0);
   html2canvas(document.getElementById('container')).then(function(canvas) {
           var a = document.createElement('a');
            a.href = canvas.toDataURL("image/jpeg").replace("image/jpeg", "image/octet-stream");
            a.download = 'image.jpg';
            a.click();
   });

若要將擷取下來的畫面讓背景呈現白色只需要將HTML修改如下:
<div id="container" style="background:#FFF">
Hello world!
</div>
