- 	 * toast 消息提示
 
- 	 * @description 此组件表现形式类似uni的uni.showToastAPI,但也有不同的地方。
 
- 	 * @tutorial https://www.uviewui.com/components/toast.html
 
- 	 * @property {String | Number}	zIndex		toast展示时的zIndex值 (默认 10090 )
 
- 	 * @property {Boolean}			loading		是否加载中 (默认 false )
 
- 	 * @property {String | Number}	message		显示的文字内容
 
- 	 * @property {String}			icon		图标,或者绝对路径的图片
 
- 	 * @property {String}			type		主题类型 (默认 default)
 
- 	 * @property {Boolean}			show		是否显示该组件 (默认 false)
 
- 	 * @property {Boolean}			overlay		是否显示透明遮罩,防止点击穿透 (默认 false )
 
- 	 * @property {String}			position	位置 (默认 'center' )
 
- 	 * @property {Object}			params		跳转的参数 
 
- 	 * @property {String | Number}  duration	展示时间,单位ms (默认 2000 )
 
- 	 * @property {Boolean}			isTab		是否返回的为tab页面 (默认 false )
 
- 	 * @property {String}			url			toast消失后是否跳转页面,有则跳转,优先级高于back参数 
 
- 	 * @property {Function}			complete	执行完后的回调函数 
 
- 	 * @property {Boolean}			back		结束toast是否自动返回上一页 (默认 false )
 
- 	 * @property {Object}			customStyle	组件的样式,对象形式
 
- 	 * @event {Function} show 显示toast,如需一进入页面就显示toast,请在onReady生命周期调用
 
- 	 * @example <u-toast ref="uToast" />
