今天抽空给大家介绍下vue和moment做的一个倒计时，具体内容如下所示：
展示样式：
<template>
<div class="table-right flex-a-center">
<div class="time-text">
<span class="timeTextSpan" v-for="item,index of h" >{{item}}</span>
<span class="timeTextSpan1" >: </span>
<span class="timeTextSpan" v-for="item,index of m" >{{item}}</span>
<span class="timeTextSpan1" >: </span>
<span class="timeTextSpan" v-for="item,index of s" >{{item}}</span>
</div>
</div>
</template>
<script>
import moment from 'moment'
export default {
props: {
endTime: { }, //接收得最后时间 2021-12-17 16：29：20
},
data() {
//这里存放数据
return {
h:'00',
m:'00',
s:'00',
timer:null
};
},
watch: {
endTime: {
handler(e) {
if (e) {
let self = this
clearInterval(this.timer)
this.timer = setInterval(function(){self.init()},1000)
}
},
deep: true,
immediate: true
}
},
mounted() {
let self = this
self.init()
clearInterval(this.timer)
this.timer = setInterval(function(){self.init()},1000)
},
//方法集合
methods: {
init(){
let time =moment(this.endTime).diff(moment())
if(time <= 0){
clearInterval(this.timer)
this.onOver()
return
}
let t = time / 1000;
let d = Math.floor(t / (24 * 3600)); //剩余天数，如果需要可以自行补上
let h = Math.floor((t - 24 * 3600 * d) / 3600) + d*24; //不需要天数，把天数转换成小时
let _h = Math.floor((t - 24 * 3600 * d) / 3600) //保留天数后得小时
let m = Math.floor((t - 24 * 3600 * d - _h * 3600) / 60);
let s = Math.floor((t - 24 * 3600 * d - _h * 3600 - m * 60));
this.h = String(h).length == 1? '0'+String(h):String(h)
this.m = String(m).length == 1? '0'+String(m):String(m)
this.s = String(s).length == 1? '0'+String(s):String(s)
},
onOver() {
this.$emit('over') //倒计时结束得回调
}
},
beforeDestroy(){
this.timer = null
clearInterval(this.timer)
}
}
</script>
