Question

假设，我有日期范围：

var start = moment('2017-08-21').startOf('isoweek').startOf('day');
var end = moment('2017-08-21').startOf('isoweek').add('days', 4).endOf('day');

我有另一个阵列：

var array = [
   {x:Mon Aug 21 2017 08:00:00 GMT+0200 (Central European Daylight Time),y:3},
   {x:Mon Aug 21 2017 08:05:00 GMT+0200 (Central European Daylight Time),y:6},
   ...
   {x:Mon Aug 22 2017 07:05:00 GMT+0200 (Central European Daylight Time),y:4},
   {x:Mon Aug 22 2017 08:05:00 GMT+0200 (Central European Daylight Time),y:3},
   {x:Mon Aug 22 2017 15:05:00 GMT+0200 (Central European Daylight Time),y:9},
   {x:Mon Aug 22 2017 22:05:00 GMT+0200 (Central European Daylight Time),y:1},
   ...
   {x:Mon Aug 23 2017 06:05:00 GMT+0200 (Central European Daylight Time),y:5},
   {x:Mon Aug 23 2017 08:00:00 GMT+0200 (Central European Daylight Time),y:3},
   {x:Mon Aug 23 2017 23:05:00 GMT+0200 (Central European Daylight Time),y:3},
   ...
   {x:Mon Aug 25 2017 07:05:00 GMT+0200 (Central European Daylight Time),y:4},
   {x:Mon Aug 25 2017 12:05:00 GMT+0200 (Central European Daylight Time),y:3},
   {x:Mon Aug 25 2017 15:05:00 GMT+0200 (Central European Daylight Time),y:8},
   {x:Mon Aug 25 2017 19:05:00 GMT+0200 (Central European Daylight Time),y:7},
   {x:Mon Aug 25 2017 23:05:00 GMT+0200 (Central European Daylight Time),y:3},
   ...
   {x:Mon Aug 27 2017 06:05:00 GMT+0200 (Central European Daylight Time),y:5},
   {x:Mon Aug 27 2017 08:00:00 GMT+0200 (Central European Daylight Time),y:3},
   {x:Mon Aug 27 2017 23:05:00 GMT+0200 (Central European Daylight Time),y:3},
   ...
];

如果时间不在以下范围内，我需要做的是更改y = 0的值：

'08：05：00'到22:05:00

表示我的输出必须如下所示：

var array = [
   {x:Mon Aug 21 2017 08:00:00 GMT+0200 (Central European Daylight Time),y:0},
   {x:Mon Aug 21 2017 08:05:00 GMT+0200 (Central European Daylight Time),y:6},
   ...
   {x:Mon Aug 22 2017 07:05:00 GMT+0200 (Central European Daylight Time),y:0},
   {x:Mon Aug 22 2017 08:05:00 GMT+0200 (Central European Daylight Time),y:3},
   {x:Mon Aug 22 2017 15:05:00 GMT+0200 (Central European Daylight Time),y:9},
   {x:Mon Aug 22 2017 22:05:00 GMT+0200 (Central European Daylight Time),y:1},
   ...
   {x:Mon Aug 23 2017 06:05:00 GMT+0200 (Central European Daylight Time),y:0},
   {x:Mon Aug 23 2017 08:00:00 GMT+0200 (Central European Daylight Time),y:0},
   {x:Mon Aug 23 2017 23:05:00 GMT+0200 (Central European Daylight Time),y:0},
   ...
   {x:Mon Aug 25 2017 07:05:00 GMT+0200 (Central European Daylight Time),y:0},
   {x:Mon Aug 25 2017 12:05:00 GMT+0200 (Central European Daylight Time),y:3},
   {x:Mon Aug 25 2017 15:05:00 GMT+0200 (Central European Daylight Time),y:8},
   {x:Mon Aug 25 2017 19:05:00 GMT+0200 (Central European Daylight Time),y:7},
   {x:Mon Aug 25 2017 23:05:00 GMT+0200 (Central European Daylight Time),y:0},
   ...
   {x:Mon Aug 27 2017 06:05:00 GMT+0200 (Central European Daylight Time),y:0},
   {x:Mon Aug 27 2017 08:00:00 GMT+0200 (Central European Daylight Time),y:0},
   {x:Mon Aug 27 2017 23:05:00 GMT+0200 (Central European Daylight Time),y:0},
   ...
];

到目前为止我一直在尝试

$.each(arr, function (key, value) {
      var date = moment(value.x);
      //if (date < start || date > end])) {
      //@TODO where i need to check time interval also
        filterArray.push({
          x: date,
          y: 0
        })
      } else {
        filterArray.push({
          x: date,
          y: value.y
        })
      }
    });

我试着查看日期范围的时间间隔，但没有运气。任何人都可以向我提出建议或帮助吗？

Answer 1

我假设您的x属性是一个JavaScript Date对象，而var date = moment(value.x);正在调用moment(Date);。

您可以使用isBetween：

检查片刻是否在两个其他时刻之间，可选择查看单位比例（分钟，小时，天等）。这场比赛是独家的。

在您的情况下，您可以将'[]'作为第四个参数传递给isBetween。

您只需使用date.isBetween(start, end, null, '[]')来检查元素是否在start和end之间。

然后，您可以使用isBetween检查您的元素时间是否在同一天的08:05:00和22:05:00构建3时刻对象之间（今天在我的示例中，因为已省略单位默认为0或当前日期，月份和年份。，如moment({unit: value, ...});的文档中所述。所以你将拥有：

today805代表08:05:00
today2205代表22:05:00
time这是当天的时刻对象，其x属性的时间（$.each循环的当前元素的时间）

因此，您可以使用time.isBetween(today805, today2205, null, '[]')检查元素的时间是否介于08:05:00和22:05:00之间。这将只比较＆＃34;＆＃34; 时间，因为三个时刻代表构造的同一天。

您可以使用时刻的getter（hours()和minutes()）以及本机Date getter来获取x元素的array属性的小时和分钟（getHours()和getMinutes()）

这是一份工作样本：

＆＃13;

var start = moment('2017-08-21').startOf('isoweek').startOf('day');
var end = moment('2017-08-21').startOf('isoweek').add(4, 'days').endOf('day');

var array = [
   {x: new Date(2017, 7, 21, 8, 0), y:3},
   {x: new Date(2017, 7, 21, 8, 5), y:6},
   //...
   {x: new Date(2017, 7, 22, 7, 5), y:4},
   {x: new Date(2017, 7, 22, 8, 5), y:3},
   {x: new Date(2017, 7, 22, 15, 5),y:9},
   {x: new Date(2017, 7, 22, 22, 5),y:1},
   //...
   //...
   //...
   {x: new Date(2017, 7, 27, 6, 5), y:5},
   {x: new Date(2017, 7, 27, 8, 0), y:3},
   {x: new Date(2017, 7, 27, 23, 5),y:3},
   //...
];

var filterArray = [];
// Today at 08:05:00
var today805  = moment({h: 8, m: 5});
// Today at 22:05:00
var today2205 = moment({h: 22, m: 5});

$.each(array, function (key, value) {
  var date = moment(value.x);
  // Create a moment object for the current day with hours and minutes of value.x
  var time = moment({h: date.hours(), m: date.minutes()});
  var yVal;
  if( date.isBetween(start, end, null, '[]') && 
      time.isBetween(today805, today2205, null, '[]') ) {
    yVal = 0;
  } else {
    yVal = value.y;
  }
  filterArray.push({
    x: date.format(),
    y: yVal
  });
});

console.log(filterArray);

从moment.js中的日期范围获取相同的时间间隔
