vue 使用 filter 过滤器转化时间戳

定义全局过滤器:

Vue.filter("formatDate", function(time) {
        let date = new Date(time*1000);//如果date为13位不需要乘1000
        let Y = date.getFullYear() + '-';
        let M = (date.getMonth()+1 < 10 ? '0'+(date.getMonth()+1) : date.getMonth()+1) + '-';
        let D = (date.getDate() < 10 ? '0' + (date.getDate()) : date.getDate()) + ' ';
        let h = (date.getHours() < 10 ? '0' + date.getHours() : date.getHours()) + ':';
        let m = (date.getMinutes() <10 ? '0' + date.getMinutes() : date.getMinutes()) + ':';
        let s = (date.getSeconds() <10 ? '0' + date.getSeconds() : date.getSeconds());
        return Y+M+D+h+m+s;
}) 

定义局部过滤器:

filters: {
      // 转化时间戳
      time(value){
        let date = new Date(value*1000);//如果date为13位不需要乘1000
        let Y = date.getFullYear() + '-';
        let M = (date.getMonth()+1 < 10 ? '0'+(date.getMonth()+1) : date.getMonth()+1) + '-';
        let D = (date.getDate() < 10 ? '0' + (date.getDate()) : date.getDate()) + ' ';
        let h = (date.getHours() < 10 ? '0' + date.getHours() : date.getHours()) + ':';
        let m = (date.getMinutes() <10 ? '0' + date.getMinutes() : date.getMinutes()) + ':';
        let s = (date.getSeconds() <10 ? '0' + date.getSeconds() : date.getSeconds());
        return Y+M+D+h+m+s;
      }
}

在模板中使用:

<el-table-column label="创建日期">
       <template v-slot="prop">
            {{prop.row.add_time | time}}
      template>
el-table-column>
