Vue自行封装常用组件-倒计时

倒计时组件，比较复杂一点，大神勿调侃，精确到毫秒，因为项目中多次出现倒计时，所以拿出来分享下

使用方法：
1.在父组件中引入"uni-countdown"
//import uniCountdown from "./uni-countdown";

2.在父组件中注册 uniCountdown
//components:{uniCountdown},

3.放在父组件中使用
//<uni-countdown></uni-countdown> 参数代码太多直接看文件里面的吧

4.调用uniCountdown组件
//this.StatusLock = true

注：index.vue为父组件，后者为子组件，效果图先上，可以先看是否是自己想要的组件，再选择使用

index.vue
