javascript - 如何在 vue js html 中根据时间显示 "Closed"或 "Open"？

Question

这是我的 json 数据，用于显示商店的营业时间:

{
    "status": true,
    "data": {
        "pid": 1,
        "bussinessName": "ard",
        "services": "looking for passionate",
        "inventory": [],
        "workHr": "Monday :9:00AM to 5:00PM,Thuesday :9:00AM to 5:00PM,Wednesday :9:00AM to 5:00PM,Tuesday : 9:00AM to 5:00PM,Friday :9:00AM to 5:00PM,Saturday :9:00AM to 5:00PM,Sunday :9:00AM to 5:00PM"
    }
}

我的 vuejs 代码是:

<script>
    new Vue({
        el: '#feed' ,
        data: {
            data: [],
        },
        mounted() {
            this.$nextTick(function() {
                var self = this;
                var id = 1;
                console.log(id)
                $.ajax({
                    url: "https://n2s.herokuapp.com/api/post/get/"+{{pid}},
                method: "GET",
                    dataType: "JSON",
                    success: function (e) {
                    if (e.status == 1) {
                        self.data = e.data;
                        console.log(e.data)

                        const workHour = e.data.workHr.split(',').map((val) => {
                            const obj = val.split(':');
                        const time = val.replace(`${obj[0]}:`, '');
                        return {
                            day: obj[0],
                            time,
                        }
                    });
                    }
                    else
                    {
                        console.log('Error occurred');}
                }, error: function(){
                    console.log('Error occurred');
                }
            });
            })
        },
    })
</script>

我使用以下代码显示今天的营业时间:

<div v-for="(item,key) in data.workHr" :key="key">
  <span v-if="new Date().getDay()-1==key">  <img src="/static/assets/img/timer.png">Today :  {{item.time}}</span>    
 </div>

除了他们的营业时间外，我还需要根据是否在他们的工作时间内显示“Closed”或“Open”。我该如何实现？

首先，您的 JSON 架构由于某些拼写错误似乎不正确。我修复了 JSON 架构并将其硬编码到代码中，并删除了 AJAX 调用以使代码可用。希望您可以自己替换 AJAX 调用。

解释
我使用了两个库来操作日期/时间。第一个是 momentjs另一个是它的插件 moment-range .然后，我用 JavaScript 格式化了您的日期，而不是在模板上进行格式化，并使用 range 方法来计算 OPENED 和 CLOSED 状态。我还添加了 parseTime 函数来解析 time 以处理 AM/PM。

window['moment-range'].extendMoment(moment);

function parseTime(time, format) {
  var add12 = false;
  if (time.indexOf('PM') > -1) {
    add12 = true;
  }
  time = moment(time.replace('AM', '').replace('PM', ''), 'hh:mm');
  if (add12) {
    time.add(12, 'hours')
  }
  return time;
}

new Vue({
  el: '#feed',
  data: {
    data: [],
  },
  mounted() {
    this.$nextTick(function() {
      var self = this;
      var id = 1;
      self.today_open = false;
      var e = {
        "status": true,
        "data": {
          "pid": 1,
          "bussinessName": "ard",
          "services": "looking for passionate",
          "inventory": [],
          "workHr": "Monday :9:00AM to 10:00PM,Tuesday :9:00AM to 5:00PM,Wednesday :9:00AM to 5:00PM,Thursday : 9:00AM to 5:00PM,Friday :9:00AM to 5:00PM,Saturday :9:00AM to 5:00PM,Sunday :9:00AM to 5:00PM"
        }
      }
      self.data = e.data;
      const workHour = e.data.workHr.split(',').map((val) => {
        const obj = val.split(':');
        const time = val.replace(`${obj[0]}:`, '');
        const time_from = time.split('to')[0].trim();
        const time_to = time.split('to')[1].trim();
        var timeWindow = moment.range(parseTime(time_from), parseTime(time_to));
        return {
          day: obj[0],
          time_from: parseTime(time_from).format('hh:mm A'),
          time_to: parseTime(time_to).format('hh:mm A'),
          today_open: timeWindow.contains(new Date())
        }
      });
      self.data.workHr = workHour
    });
  }
})
