推荐答案

大多数编辑使用 contentEditable 属性。只需在任何HTML元素上设置即可在现代用户代理中进行编辑，复制和粘贴，拼写检查，格式化等。

Most editors use the contentEditable property. Simply setting it on any HTML element enables editing, copy&paste, spell checking, formatting etc. in modern user agents.

但是，Google文档使用contentEditable。相反，他们在JavaScript中实现了自己的呈现引擎。除非你计划在google文档的规模上的项目（即你至少有3个人愿意在渲染引擎上全职工作），contentEditable是要走的路。

However, google docs specifically does not use contentEditable. Instead, they implemented their own rendering engine in JavaScript. Unless you plan a project on the scale of google docs (i.e. you have at least, say, 3 people willing to work full-time on the rendering engine), contentEditable is the way to go.
