- 	 * mask 遮罩
 
- 	 * @description 创建一个遮罩层,用于强调特定的页面元素,并阻止用户对遮罩下层的内容进行操作,一般用于弹窗场景
 
- 	 * @tutorial https://www.uviewui.com/components/mask.html
 
- 	 * @property {Boolean} show 是否显示遮罩(默认false)
 
- 	 * @property {String Number} z-index z-index 层级(默认1070)
 
- 	 * @property {Object} custom-style 自定义样式对象,见上方说明
 
- 	 * @property {String Number} duration 动画时长,单位毫秒(默认300)
 
- 	 * @property {Boolean} zoom 是否使用scale对遮罩进行缩放(默认true)
 
- 	 * @property {Boolean} mask-click-able 遮罩是否可点击,为false时点击不会发送click事件(默认true)
 
- 	 * @event {Function} click mask-click-able为true时,点击遮罩发送此事件
 
- 	 * @example <u-mask :show="show" @click="show = false"></u-mask>
