Question

我正在使用Angular 5中的moment.js。

我有这样的数组：

public lineChartLabels: Array<any> = [  "2018/26/02 10:01:00", "2018/26/02 10:02:00", "2018/26/02 10:03:00", "2018/26/02 10:04:00", "2018/26/02 10:05:00", "2018/26/02 10:06:00", "2018/26/02 10:07:00", "2018/26/02 10:08:00", "2018/26/02 10:09:00", "2018/26/02 10:10:00", "2018/26/02 10:11:00", "2018/26/02 10:12:00","2018/26/02 10:13:00", "2018/26/02 10:14:00", "2018/26/02 10:15:00" ];

我有timeStart;和timeEnd;。我只是先报告，我以同样的方式初始化

let timeStart = moment();
timeStart.format('YYYY/MM/DD HH:mm:ss');
timeStart.year(2018);
timeStart.month(2);
timeStart.date(26);
timeStart.hour(10);
timeStart.minute(10);
timeStart.second(0);

timeEnd我使用timeStart.hour(10); timeStart.minute(13);

现在我必须实施这个循环：

for( let i = 0; i < this.lineChartLabels.length; i++ ){
  if (moment(this.lineChartsLabels[i]).isBetween(timeStart, timeEnd) ) {
    console.log ( 'true' );
  }
  else {
    console.log ( 'false' );
  }
}

但它不起作用。

你知道我该如何解决？

Answer 1

您的代码有两个问题：

由于moment(String)（ISO 8601或RFC 2822）无法识别lineChartLabels值，因此您必须使用moment(String, String)传递格式作为第二个参数（{{1}在你的情况下）
JavaScript月份已编入索引，因此month()：

获取或设置月份。

接受0到11之间的数字。如果超出范围，它将会冒泡到年份。

您的'YYYY/DD/MM HH:mm:ss'和timeStart代表3月26日

timeEnd

const lineChartLabels = [  "2018/26/02 10:01:00", "2018/26/02 10:02:00", "2018/26/02 10:03:00", "2018/26/02 10:04:00", "2018/26/02 10:05:00", "2018/26/02 10:06:00", "2018/26/02 10:07:00", "2018/26/02 10:08:00", "2018/26/02 10:09:00", "2018/26/02 10:10:00", "2018/26/02 10:11:00", "2018/26/02 10:12:00","2018/26/02 10:13:00", "2018/26/02 10:14:00", "2018/26/02 10:15:00" ];

let timeStart = moment();
timeStart.year(2018);
timeStart.month(2-1); // Months are 0 index, 2 stands for March
timeStart.date(26);
timeStart.hour(10);
timeStart.minute(10);
timeStart.second(0);

let timeEnd = moment(timeStart).hour(10).minute(13);

console.log(timeStart.format());
console.log(timeEnd.format());

for( let i = 0; i < lineChartLabels.length; i++ ){
  if (moment(lineChartLabels[i], 'YYYY/DD/MM HH:mm:ss').isBetween(timeStart, timeEnd) ) {
    console.log ( 'true' );
  }
  else {
    console.log ( 'false' );
  }
}

选择使用moment.js设置的2个值之间的值
