通过javascript将div内容转换为图像 [英] Converting a div content to an image via javascript

问题描述

如何将div标签的内容转换为图片并通过javascript保存到本地文件夹？我知道必须有出路，但我无法找到它。任何帮助将不胜感激 。

解决方案

Canvas。 drawImage 支持Image，Canvas和视频元素。有些人说，它可能会支持DOMElement。

有很多以C（或C ++）编写的开源浏览器。有 Emscripten 项目，可以将C ++代码转换为Javascript。因此，您可以在浏览器中运行您自己的浏览器并使用它来呈现您的HTML。

在浏览器内部运行浏览器根本不奇怪。例如。有一个项目，它在浏览器中模拟x86机器 - http://copy.sh/v24/ 。

How to convert the content of a div tag to an image and save it to a local folder via javascript ? I know there must be a way out but i am unable to find it . Any help would be greatly appreciated . Thanks in advance.

解决方案

Canvas.drawImage supports Image, Canvas and Video elements. Some people say, that it may support DOMElement in the future.

There are many open-source browsers written in C (or C++). There is Emscripten project, which can convert C++ code to Javascript. So you can run your own browser inside a browser and use it to render your HTML.

Running browser inside a browser is not strange idea at all. E.g. there is a project, that emulates x86 machine in a browser - http://copy.sh/v24/.
