javascript - 如何从 jquery 或 javascript 中的静态日期数组中获取日期范围

Question

我想从数组的静态日期创建日期范围。
这是我想要的示例:

var collDates = [
  "2017/01/01", 
  "2017/01/02", 
  "2017/01/03", 
  "2017/01/04", 
  "2017/01/08", 
  "2017/01/09"
];

这应该转换为:

[
  { start_date: "2017/01/01", end_date: "2017/01/04" }, 
  { start_date: "2017/01/08", end_date: "2017/01/09" }
];

我已经解决了这个问题，这里是一个示例代码。

var staticDates = ["2017/01/01", "2017/01/02", "2017/01/03", "2017/01/04", "2017/01/08", "2017/01/09", "2017/01/10", "2017/01/11", "2017/01/12", "2017/01/13", "2017/01/14", "2017/01/15", "2017/01/16", "2017/01/17", "2017/01/18", "2017/01/19", "2017/01/20", "2017/01/21", "2017/01/22", "2017/01/23", "2017/01/24", "2017/01/25", "2017/01/26", "2017/01/27", "2017/01/28", "2017/01/29"];
var coll_dateIntervals = []; 
var arr_temp = []; 
var i = 1;
$.each(staticDates, function(index, moment_date){ 

//Day difference in # of days 
 var diff = Math.abs(moment(staticDates[index]).diff(staticDates[index + 1], "days")); 

   arr_temp.push(moment_date); 

  //Check the date difference in days. 
  if(diff <= 1 && diff !== undefined){ 

   //If the difference is 1, than add the date to the temporary array 
   arr_temp.push(moment_date); 

  //If it's more than 1 day, or the last object 
 } else if (diff > 1 || diff === undefined){ 
   //Store the interval in an object 
   console.log(arr_temp[arr_temp.length - 1]);
   var obj_dateInterval = { start_date: moment(arr_temp[0],  "YYYY/MM/DD").format('YYYY-MM-DD'), end_date:    moment(arr_temp[arr_temp.length - 1], "YYYY/MM/DD").format('YYYY-MM-DD')}; 
   coll_dateIntervals.push(obj_dateInterval); 

   //Empty the array to start the new loop 
   arr_temp = [];  

 }

}); 
console.log(coll_dateIntervals);
