Question

我有以下JSON数组（注意这些只是数组的第5和第6个元素）：

[   
{ 
    Day: 'Mon',
    EndTime: '{ts \'1970-01-01 18:00:00\'}',
    StartTime: '{ts \'1970-01-01 16:30:00\'}',
    courseName: 'Computer Science 250: Introduction to Website Design',
    Credits: '4' 
},  
{   
    Day: 'Mon',
    EndTime: '{ts \'1970-01-01 18:30:00\'}',
    StartTime: '{ts \'1970-01-01 17:30:00\'}',
    courseName: 'Math 220: Differential Equations',
    Credits: '3' 
}
]

数组中的数据按“EndTime”的值排序。当我尝试检查对象在i - 1（18:00:00）的结束时间是否在下一个对象的开始时间和结束时间之间时（在i，如果是17:30:00到18:30： 00）我应该成为现实，但isBetween方法返回false。

我怎么能解决这个问题，我知道我犯了一些简单的错误？

这是我的代码：

for(let i = 1; i < monday.length-1; i++) {

const year = '1970-01-01';
const format = 'DD/MM/YYYY hh:mm:ss a';

  var next_endtime = monday[i].EndTime.substr(16, 8);
  var next_starttime = monday[i].StartTime.substr(16, 8);
  var prev_endtime = monday[i-1].EndTime.substr(16, 8);

  var plesson_e = moment(year + 'T' + prev_endtime, format), 
      nlesson_start = moment(year + 'T' + next_starttime, format), 
      nlesson_end = moment(year + 'T' + next_endtime, format);

  var testbool = moment(plesson_e).isBetween(nlesson_start, nlesson_end, 'time');

console.log(testbool);
}

日期时间或格式有问题，你传递给片刻JS，它对我有用：

＆＃13;

const monday = [{
    Day: 'Mon',
    EndTime: '{ts \'1970-01-01 18:00:00\'}',
    StartTime: '{ts \'1970-01-01 16:30:00\'}',
    courseName: 'Computer Science 250: Introduction to Website Design',
    Credits: '4'
  },
  {
    Day: 'Mon',
    EndTime: '{ts \'1970-01-01 18:30:00\'}',
    StartTime: '{ts \'1970-01-01 17:30:00\'}',
    courseName: 'Math 220: Differential Equations',
    Credits: '3'
  }
]

const format = 'hh:mm:ss a';

var next_endtime = monday[1].EndTime.substr(16, 8);
var next_starttime = monday[1].StartTime.substr(16, 8);
var prev_endtime = monday[0].EndTime.substr(16, 8);

var plesson_e = moment(prev_endtime, format),
  nlesson_start = moment(next_starttime, format),
  nlesson_end = moment(next_endtime, format);

var testbool = moment(plesson_e).isBetween(nlesson_start, nlesson_end, 'time');

console.log(next_endtime, next_starttime, prev_endtime);
console.log(nlesson_end, nlesson_start, plesson_e);
console.log(testbool);

Answer 2

您传递给片刻的字符串与指定的格式不符：

 spl_autoload_register(function ($class) {

 }); //This part here

尝试将格式值更改为：

const year = '1970-01-01'; // => see the '-', and the year is first
const format = 'DD/MM/YYYY hh:mm:ss a'; // => you put '/' and day first
