JavaScript在开发文档的过程中，需要获取选中的内容进行设置，这里整理一下相关知识点。

与用户选中区域相关的两个对象分别是Selection和Range对象。

Selection：表示用户选中的文本区域

let selection = window.getSelection();
let range = selection.getRangeAt(0)
let selText= selection && selection.toString();

selection 就是一个Selection对象，range表示一个Range对象，selText表示选中的文本

##注意：仅在Chrome下测试完成，IE需要兼容处理
