如何获得某个日期区间内的数据

[cyyjm]

我有一个json，我想对它进行处理，仅留下上个月14号到这个月13号的数据。
例如：对于这个json(arr)，我想分别获得 result1,result2

let arr = [
{'name':'A','time':'2019/1/8 10:00:00'},
{'name':'B','time':'2019/1/13 10:00:00'},
{'name':'C','time':'2019/1/23 10:00:00'},
{'name':'D','time':'2019/2/8 10:00:00'},
{'name':'E','time':'2019/2/18 10:00:00'},
{'name':'F','time':'2019/3/1 10:00:00'},
{'name':'G','time':'2019/1/15 10:00:00'},
{'name':'H','time':'2019/2/14 10:00:00'}
];
result1 = [
{'name':'C','time':'2019/1/23 10:00:00'},
{'name':'D','time':'2019/2/8 10:00:00'},
{'name':'G','time':'2019/1/15 10:00:00'}
];
result2 = [
{'name':'E','time':'2019/2/18 10:00:00'},
{'name':'F','time':'2019/3/1 10:00:00'},
{'name':'H','time':'2019/2/14 10:00:00'}
];

let arr = [
   {'name':'A','time':'2019/1/8 10:00:00'},
   {'name':'B','time':'2019/1/13 10:00:00'},
   {'name':'C','time':'2019/1/23 10:00:00'},
   {'name':'D','time':'2019/2/8 10:00:00'},
   {'name':'E','time':'2019/2/18 10:00:00'},
   {'name':'F','time':'2019/3/1 10:00:00'},
   {'name':'G','time':'2019/1/15 10:00:00'},
   {'name':'H','time':'2019/2/14 10:00:00'}
];
var time1 = new Date('2019/1/14 00:00:00').getTime();
var time2 = new Date('2019/2/14 00:00:00').getTime();
var time3 = new Date('2019/3/14 00:00:00').getTime();
var result1 = arr.filter(function(v, i){
	var t = new Date(v.time).getTime();
	return t >= time1 && t < time2;
});
var result2 = arr.filter(function(v, i){
	var t = new Date(v.time).getTime();
	return t >= time2 && t < time3;
});
