从HTML到DOM转换回HTML是否标准化？ [英] Is the conversion from HTML to DOM and back to HTML standardized?

问题描述

我正在研究将使用ContentEditable的富文本编辑器。加载到浏览器中的文档（来自Web服务器）不得以任何方式被转换为DOM，然后单独转换为HTML（假设用户未做任何更改）。

I'm working on an rich-text editor that will be using ContentEditable. It's imperative that a document that is loaded into the browser (from the web server) is not altered in any way by the conversion to DOM, and then back to HTML alone (assuming the user has not made any changes).

如果HTML文档在第一次被浏览器创建和保存时被修改，但后来不应该再次发生，这只需要所有浏览器根据等效的HTML和基于等效DOM的相同HTML输出。这是我可以依赖的东西吗？

It's alright if the HTML document is modified the first time it's created and saved by a browser, but subsequently should not occur again, which simply requires that all browsers will produce the same DOM based on equivalent HTML, and the same HTML output based on equivalent DOMs. Is this something that I can rely upon?

推荐答案

以开始的标记< div id ='mydiv'>< / div> 。在IE9中，变成< div id =mydiv>< / div> 。在IE8中，它变成< DIV id = mydiv>< / DIV>

Take markup that starts as <div id='mydiv'></div>. In IE9 that becomes <div id="mydiv"></div>. In IE8, it becomes <DIV id=mydiv></DIV>
