将时间分成 30 分钟块

break times into 30 minute chunks

本文关键字：分钟 时间      更新时间：2023-09-26

我有两个日期开始和结束

"start" : "Wed Jan 27 2016 21:00:00 GMT-0500",
"end" : "Thu Jan 27 2016 23:30:00 GMT-0500"

我想把这次分成几个块，比如

"start" : "Wed Jan 27 2016 21:00:00 GMT-0500",
"end" : "Thu Jan 27 2016 21:30:00 GMT-0500"
----------------------------------------------
"start" : "Wed Jan 27 2016 21:30:00 GMT-0500",
"end" : "Thu Jan 27 2016 22:00:00 GMT-0500"
----------------------------------------------
"start" : "Wed Jan 27 2016 22:00:00 GMT-0500",
"end" : "Thu Jan 27 2016 22:30:00 GMT-0500"
----------------------------------------------
"start" : "Wed Jan 27 2016 22:30:00 GMT-0500",
"end" : "Thu Jan 27 2016 23:00:00 GMT-0500"
----------------------------------------------
"start" : "Wed Jan 27 2016 23:00:00 GMT-0500",
"end" : "Thu Jan 27 2016 23:30:00 GMT-0500"

有没有办法使用 moment.js 或 javascript 来做到这一点？

我们可以像这样将时间分解为块：

 var time = {
   "start": "Wed Jan 27 2016 21:00:00 GMT-0500",
   "end": "Thu Jan 27 2016 23:30:00 GMT-0500"
 };
 var startTime = new Date(time.start).getTime();
 var endTime = new Date(time.end).getTime();
 var diff = endTime - startTime;
 var chunks = [];
 var hold = startTime;
 var threshold = (60 * 30 * 1000); //30minutes
 for (var i = (startTime + threshold); i <= endTime; i += (threshold)) {
   var newEndTime = new Date(i);
   chunks.push({
     start: new Date(hold),
     end: newEndTime
   });
   hold = newEndTime;
 }
 console.log(chunks)

使用时刻时区（假设您添加了时区），这会将您的间隔写入控制台.log;

var start = moment.tz('2016-01-27 21:00', 'America/New_York');
var end   = moment.tz('2016-01-27 23:30', 'America/New_York');
while(start < end) {
  console.log('Start: ' + start.format());
  start = start.add(30, 'minutes')
  console.log('End:   ' + start.format());
  console.log();
}
Start: 2016-01-27T21:00:00-05:00
End:   2016-01-27T21:30:00-05:00
Start: 2016-01-27T21:30:00-05:00
End:   2016-01-27T22:00:00-05:00
Start: 2016-01-27T22:00:00-05:00
End:   2016-01-27T22:30:00-05:00
Start: 2016-01-27T22:30:00-05:00
End:   2016-01-27T23:00:00-05:00
Start: 2016-01-27T23:00:00-05:00
End:   2016-01-27T23:30:00-05:00

var startTime = new Date(start).getTime();
var endTime = new Date(end).getTime();
var duration = 1000 * 60 * 30;
var times = [] ;
var arr_len = (startTime - endTime)/duration;
for(i=0; i< arr_len; i++){
    times.push(new Date(startTime + duration));
}

然后你得到这些块
