为wangEditor扩展,增加全屏 查看源码功能

wangEditorExt.js

/**
 * wangEditor扩展,增加全屏 查看源码功能
 * 传入均为 editor实例,非css选择器
 * 依赖jquery 如果是layui之类的需要在layui.use方法中使用
 * 全屏功能需要引入 wangEditor-fullscreen.css
 * @author [email protected]
 * @date 2018.8.30 am 10:00
 * @date 2018.9.18 pm 15:00 支持多个编辑器
 * 使用方法:
 * E.fullscreen.init(editor);
 * E.viewSource.init(editor);
