|  * countDown 倒计时
 | ||
|  * @description 该组件一般使用于某个活动的截止时间上,通过数字的变化,给用户明确的时间感受,提示用户进行某一个行为操作。
 | ||
|  * @tutorial https://www.uviewui.com/components/countDown.html
 | ||
|  * @property {String Number} timestamp 倒计时,单位为秒
 | ||
|  * @property {Boolean} autoplay 是否自动开始倒计时,如果为false,需手动调用开始方法。见官网说明(默认true)
 | ||
|  * @property {String} separator 分隔符,colon为英文冒号,zh为中文(默认colon)
 | ||
|  * @property {String Number} separator-size 分隔符的字体大小,单位rpx(默认30)
 | ||
|  * @property {String} separator-color 分隔符的颜色(默认#303133)
 | ||
|  * @property {String Number} font-size 倒计时字体大小,单位rpx(默认30)
 | ||
|  * @property {Boolean} show-border 是否显示倒计时数字的边框(默认false)
 | ||
|  * @property {Boolean} hide-zero-day 当"天"的部分为0时,隐藏该字段 (默认true)
 | ||
|  * @property {String} border-color 数字边框的颜色(默认#303133)
 | ||
|  * @property {String} bg-color 倒计时数字的背景颜色(默认#ffffff)
 | ||
|  * @property {String} color 倒计时数字的颜色(默认#303133)
 | ||
|  * @property {String} height 数字高度值(宽度等同此值),设置边框时看情况是否需要设置此值,单位rpx(默认auto)
 | ||
|  * @property {Boolean} show-days 是否显示倒计时的"天"部分(默认true)
 | ||
|  * @property {Boolean} show-hours 是否显示倒计时的"时"部分(默认true)
 | ||
|  * @property {Boolean} show-minutes 是否显示倒计时的"分"部分(默认true)
 | ||
|  * @property {Boolean} show-seconds 是否显示倒计时的"秒"部分(默认true)
 | ||
|  * @event {Function} end 倒计时结束
 | ||
|  * @event {Function} change 每秒触发一次,回调为当前剩余的倒计秒数
 | ||
|  * @example <u-count-down ref="uCountDown" :timestamp="86400" :autoplay="false"></u-count-down>
