You get error message Deprecated method document.getSelection() called.您收到错误消息Deprecated method document.getSelection()调用。 Please use window.getSelection() instead." in Firefox which means document.getSelection() is a deprecated method.请改用window.getSelection() 。” 在 Firefox 中，这意味着document.getSelection()是一个已弃用的方法。

They seem to be the same:它们似乎是一样的：

https://w3c.github.io/selection-api/#dom-document-getselection https://w3c.github.io/selection-api/#dom-document-getselection

getSelection() method getSelection()方法
The method must return the selection associated with this if this has an associated browsing context, and it must return null otherwise.如果this具有关联的浏览上下文，则该方法必须返回与this关联的选择，否则它必须返回 null。

https://w3c.github.io/selection-api/#dom-window-getselectionhttps://w3c.github.io/selection-api/#dom-window-getselection

getSelection() method getSelection()方法
The method must invoke and return the result of getSelection() on this 's Window.document attribute.该方法必须在this的Window.document属性上调用并返回getSelection()的结果。

Editors of MDN say they're equivalent: MDN 的编辑说它们是等价的：

You can call Window.getSelection() , which works identically to Document.getSelection() .您可以调用Window.getSelection() ，其工作方式与Document.getSelection()相同。
