如何将光标移动到 contenteditable 实体的末尾 - How to move cursor to end of contenteditable entity

问题：

I need to move caret to end of contenteditable node like on Gmail notes widget.我需要像 Gmail 笔记小部件一样将插入符号移动到contenteditable节点的末尾。

I read threads on StackOverflow, but those solutions are based on using inputs and they doesn't work with contenteditable elements.我在 StackOverflow 上阅读了线程，但这些解决方案基于使用输入，并且它们不适用于contenteditable元素。
