Javascript循环并插入新对象

Question

我用ajax得到这个数据：

[{"id":125,"price":225,"start":"Tue, 26 Apr 2016 00:00:00 +0000","user_id":8},{"id":124,"price":200,"start":"Wed, 27 Apr 2016 00:00:00 +0000","user_id":8},{"id":121,"price":67,"start":"Sat, 23 Apr 2016 00:00:00 +0000","user_id":8},{"id":114,"price":45,"start":"Sun, 08 May 2016 00:00:00 +0000","user_id":9},{"id":113,"price":55,"start":"Sun, 24 Apr 2016 00:00:00 +0000","user_id":8},{"id":111,"price":55,"start":"Wed, 01 Jun 2016 00:00:00 +0000","user_id":11},{"id":110,"price":53,"start":"Fri, 03 Jun 2016 00:00:00 +0000","user_id":8},{"id":107,"price":53,"start":"Wed, 03 Aug 2016 00:00:00 +0000","user_id":8},{"id":106,"price":55,"start":"Mon, 01 Aug 2016 00:00:00 +0000","user_id":8},{"id":105,"price":53,"start":"Tue, 16 Aug 2016 00:00:00 +0000","user_id":8},{"id":104,"price":55,"start":"Thu, 21 Apr 2016 00:00:00 +0000","user_id":11},{"id":101,"price":57,"start":"Wed, 17 Aug 2016 00:00:00 +0000","user_id":8}]

所以你可以看到有start数据。 我也有：

var start = '04/17/2016 12:00 am';
var end = '09/20/2016 12:01 am';

现在我需要在今天从使循环一天start到end ，检查日（日）excist成JSON，如果不增加新的数据到JSON：

{"id":0,"price":100,"start":"DATE","user_id":0}

最好的方法是什么？

更新：我创建了一个从开始到结束的新日期，但现在我需要将 json 放入新数组中： http : //jsbin.com/qekijumobe/edit?js,output

我的另一个答案在那里有问题，这就是我之后提出的：

首先，创建一个 foreach 循环，循环遍历数组中的所有对象

for (var obj of objArray) {} //Use "of" instead of "in" tk get the values and not the indices

然后，在此循环内，检查对象的每个字段，如果它们相同，则 abd 如果它们相同，则中断循环，否则，如果没有匹配的对象，则将其推送到数组中。

function isInArray(yourObj) {
    for (var obj of objArray) {
        if (obj.id == yourObj.id && obj.start == yourObj.start && obj.price == yourObj.price && obj.user_id == yourObj.user_id)
             return true;
     }
    return false;
}
