使用javascript将内容从iframe contenteditable绘制到html5画布上

Question

有没有办法在html5画布上绘制或填充iframe的内容，其中contenteditable设置为true？

Answer 1

No. You cannot capture the browser's rendering of HTML elements as a picture with a canvas.

The only thing close to what you are describing is that you can take a serialized SVG file, get the browser to render it as an img element, and then use drawImage() to write that image to the canvas .
