javascript 获取之间的时间

Question

我有一个使用 google api 返回时间的 ajax。我想要的是如果时间在上午 9:30 到晚上 7:30 之间输出一些数据。然而我的条件不行。您对此有什么建议或想法吗？预先感谢您。

这个条件不起作用。

if ((currentHours >= 9) && currentMinutes >= 30 && (currentHours <= 19) && currentMinutes <= 30) {  }

这是我的ajax。

var loc = '35.652832, 139.839478' // Tokyo expressed as lat,lng tuple
var targetDate = new Date() // Current date/time of user computer
var timestamp = targetDate.getTime() / 1000 + targetDate.getTimezoneOffset() * 60 // Current UTC date/time expressed as seconds since midnight, January 1, 1970 UTC
var apikey = 'myKey'
var apicall = 'https://maps.googleapis.com/maps/api/timezone/json?location=' + loc + '&timestamp=' + timestamp + '&key=' + apikey

$.ajax({
  async: false,
  type: "POST",
  url: apicall,
  success: function (response) {
    var offsets = response.dstOffset * 1000 + response.rawOffset * 1000 // get DST and time zone offsets in milliseconds
    var localdate = new Date(timestamp * 1000 + offsets) // Date object containing current time of Tokyo (timestamp + dstOffset + rawOffset)
    var currentHours = localdate.getHours();
    var currentMinutes = localdate.getMinutes();
    var currentSeconds = localdate.getSeconds();
    currentMinutes = (currentMinutes < 10 ? "0" : "") + currentMinutes;
    currentSeconds = (currentSeconds < 10 ? "0" : "") + currentSeconds;
    currentTimeString = currentHours + ":" + currentMinutes;
    console.log('currentimestring ' + currentTimeString);
    // console.log(currentMinutes);
    if ((currentHours >= 9) && currentMinutes >= 30 && (currentHours <= 21) && currentMinutes <= 30) {
      _isSupportHoursResult = true;
      console.log(_isSupportHoursResult);
      if (_isSupportHoursResult) {
        jpsupp = true;
        console.log(jpsupp);
      } else {
        // window.location = "/jpprechatform/OffSupportRedirect.aspx?accessID=" + inAccessID;
        jpsupp = false;
      }
    } else {
      console.log('closing time');
    }
    console.log(localdate.toLocaleTimeString()) // Display current Tokyo date and time
  },
  error: function (xmlHttpRequest, error) {
    _isSupportHoursResult = false;
  },
  complete: function (response) {
  }
});

根据您的情况，您已使用(currentMinutes >= 30 && currentMinutes <= 30)因为它变得矛盾。这似乎是问题所在。你可以使用:

if((currentHours > 9 && currentHours < 19) || (currentHours === 9 && currentMinutes >= 30) || (currentHours === 19 && currentMinutes <= 30)){}
