wangeditor 使用

富文本编辑器官网：
https://www.wangeditor.com
文档地址:
https://doc.wangeditor.com

# 安装wangeditor
npm i wangeditor --save

# 引入
import E from "wangeditor"

# 初始化
const editor = new E("#div1");

# 创建
editor.create();

# 获取元素
editor.txt.html();
注：要注意创建的优先级，举个例子：如果富文本编辑器在表单中，
首先表单要创建完成后，才能创建富文本

使用案例:
