您可以将元素的内容克隆到画布中吗? [英] Can you clone contents of an element into canvas?

问题描述

我想知道是否可以将HTML元素克隆到画布中.因此，查看此 JSFiddle ，您如何将其复制到画布中?

I was wondering if it's possible to clone an HTML element into canvas. So looking at this JSFiddle, how would you duplicate it into canvas?

我已经看到了将DOM对象绘制到画布中的方法元素，但我很好奇是否有一种方法可以做到这一点.

I've seen ways to draw DOM objects into a canvas element, but I was curious if there was a way to do it differently.

<p>Html</p>
<div id="clone-me">
  <div id="square">
  </div>
</div>

<p>Canvas</p>
<canvas width="200" height="200"></canvas>

#clone-me {
  width: 200px;
  height: 200px;
  background: #333;
}

#square {
  width: 70px;
  height: 70px;
  background: red;
}

推荐答案

您可以使用 html2canvas 进行操作它，您可以在 JSFiddle 中查看演示.

You can use html2canvas to do it, you can checkout the demo at this JSFiddle.

html2canvas(document.getElementById('clone-me'), {
    onrendered: function(canvas) {
        var canvas1 = document.getElementById('canvas1');
        var ctx = canvas1.getContext('2d');
        ctx.drawImage(canvas, 0, 0);
    }
});
