如何按日期排序对象的JavaScript数组 [英] How to sort a javascript array of objects by date

问题描述

我想排序的对象包含每个对象的数组

I am trying to sort an array of objects with each object containing

var recent = [{id: "123",age :12,start: "10/17/13 13:07"} , {id: "13",age :62,start: "07/30/13 16:30"}];

日期格式为： MM / DD / YY HH：MM

我想日期的顺序与最近的第一排序。如果日期是相同的，应该及时进行排序。

I want to sort in order of date with the most recent first. If date is same it should be sorted on time.

我尝试了下面的排序功能。但它不工作。

I tried out the below sort function. But it is not working.

recent.sort(function(a,b))
{
    a = new Date(a.start);
    b = new Date(b.start);
    return a-b;
});

另外我应该如何通过排序的对象循环？是这样的：

Also how should I iterate through the objects for sorting? Something like:

for (var i = 0; i < recent.length; i++)
    {
        recent[i].start.sort(function (a, b)
        {
            a = new Date(a.start);
            b = new Date(b.start);
            return a-b; 
        } );
    }

有可以是任何数量的数组中的对象

There can be any number of objects in the array.

推荐答案

正如已指出了意见，最近的定义是不正确的JavaScript。

As has been pointed out in the comments, the definition of recent isn't correct javascript.

不过，假设日期是字符串：

But assuming the dates are strings:

var recent = [
    {id: 123,age :12,start: "10/17/13 13:07"}, 
    {id: 13,age :62,start: "07/30/13 16:30"}
];

然后进行排序是这样的：

then sort like this:

recent.sort(function(a,b) { 
    return new Date(a.start).getTime() - new Date(b.start).getTime() 
});
