时间戳转时间 只显示年月日

方法1直接在wxml里面写

<wxs module="filter">
    var day= function(value) {
      console.log(value)
      // value = value.replace(".000+0000","Z");
      var time = getDate(value);
      var year = time.getFullYear();
      var month = time.getMonth() + 1;
      var date = time.getDate();
      var hour = time.getHours();
      var minute = time.getMinutes();
      var second = time.getSeconds();
      month = month < 10 ? "0" + month : month;
      date = date < 10 ? "0" + date : date;
      hour = hour < 10 ? "0" + hour : hour;
      minute = minute < 10 ? "0" + minute : minute;
      second = second < 10 ? "0" + second : second;
      // return year + "-" + month + "-" + date + " " + hour + ":" + minute + ":" + second;
      return year + "-" + month + "-" + date;
    }
    module.exports.day= day
</wxs>
// 使用
<view>{{filter.day(1621409888000)}}</view>

方法2 创建day.wxs文件

var filter = {
  day: function (value) {
      //不能使用 new Date()
      var time = getDate(value);
      var year = time.getFullYear();
      var month = time.getMonth() + 1;
      var date = time.getDate();
      var hour = time.getHours();
      var minute = time.getMinutes();
      var second = time.getSeconds();
      month = month < 10 ? "0" + month : month;
      date = date < 10 ? "0" + date : date;
      hour = hour < 10 ? "0" + hour : hour;
      minute = minute < 10 ? "0" + minute : minute;
      second = second < 10 ? "0" + second : second;
      return year + "-" + month + "-" + date + " " + hour + ":" + minute + ":" + second;
  }
}
// 导出对外暴露的属性
module.exports = {
  day: filter.day
}

wxml引入使用

<wxs module="filter" src="./day.wxs"></wxs> 
<view>{{filter.day(1621409888000)}}</view>
