需要对预约单进行超时计算，但是后台和客户端时间不能保证一定一直，所以后台返回客户提交时间和请求结束时间的时间差进行计算。
效果如下(此处只是demo效果，所以有点丑。)
父页面
<template>
<div>
<div class="dateDiv" :key="index" v-for="(item,index) in TimeArray">
<p>{{item.name}}</p>
<dateComponent :index="index" :key="item.timeDif" ref="dateComponent" :dateTimeStamp="item.timeDif"></dateComponent>
<el-button @click="delUnit(index)">删除</el-button>
</div>
</div>
</template>
<script>
import datajson from '../index/data.json'
import dateComponent from './dateComponent'
export default {
name:'timestamp',
components:{
dateComponent
},
data(){
return {
TimeArray: datajson.timestamp.TimeArray
/*
"timestamp":{
"TimeArray":[{
"name":"预约单2",
"timeDif":"855000"
},{
"name": "预约单2",
"timeDif": "801000"
},{
"name": "预约单3",
"timeDif": "95000"
},{
"name": "预约单4",
"timeDif": "45000"
},{
"name": "预约单5",
"timeDif": "495000"
},{
"name": "预约单6",
"timeDif": "195000"
}]
}
*/
}
},
methods:{
delUnit:function (index) {
this.TimeArray.splice(index,1)
}
}
}
</script>
<style scoped>
.dateDiv{
display: inline-block;
border: 1px solid #e5e5e5;
width: 200px;
height: 80px;;
}
</style>
超时计算组件 overtimeComponent.vue
<template>
<div>
<span>{{formatTimeStamp}}</span>
</div>
</template>
<script>
export default {
props:["dateTimeStamp","index"],
name:'dateComponent',
data(){
return {
flag:false,
formatTimeStamp:"",
interval : ""
}
},
mounted() {
var difValue = parseInt(this.dateTimeStamp);
this.formatTimeStamp = this.setResultStr(difValue)
this.interval = setInterval(() => {
difValue += 1000
this.formatTimeStamp = this.setResultStr(difValue)
}, 1000);
},
beforeDestroy (){
clearInterval(this.interval)
},
methods:{
setResultStr:function (difValue) {
var day = Math.floor(difValue / 1000 / 60 / 60 / 24);//天
difValue = difValue % (1000 * 60 * 60 * 24);
var hour = Math.floor(difValue / 1000 / 60 / 60);//小时
difValue = difValue % (1000 * 60 * 60);
var min = Math.floor(difValue / 1000 / 60);//分钟
difValue = difValue % (1000 * 60);
var second = Math.floor(difValue / 1000);
if(day === 0 && hour==0 && min == 0){
return "超时:" + second + "秒"
}else if(day === 0 && hour==0){
return "超时:" + min + "分" + second + "秒"
}else if(day === 0){
return "超时:" + hour + "小时" + min + "分" + second + "秒"
}else{
return "超时:" + day + "天" + hour + "小时" + min + "分" + second + "秒"
}
}
}
}
</script>
<style scoped>
</style>
