wangEditor默认是没有源码模式的，如果想编辑源码实现不了。
想要增加源码模式，我们就需要增加一个自定义菜单。
下面是wangEditor增加源码模式的代码：

this.active()

this.unActive()
}
}
}
// 注册菜单
const menuKey = 'htmlMenuKey' // 菜单 key ，各个菜单不能重复
editor.menus.extend('htmlMenuKey', htmlMenu)
// 将菜单加入到 editor.config.menus 中
// 也可以通过配置 menus 调整菜单的顺序，参考【配置菜单】部分的文档
editor.config.menus = editor.config.menus.concat(menuKey)
editor.create()
