javascript - 将时间分成 30 分钟的小块

Question

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"

我想把这段时间分成如下几 block

"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？

Answer 1

我们可以像这样把时间分成几 block :

 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)
