按日期排序多维数组

我有一个格式如下的数组:

arr = [
    {
     'thing':'thing',
     'thing2':'thing',
     'date':'28/07/2014 14:16'
    },
    {
     'thing':'thing',
     'thing2':'thing',
     'date':'27/07/2014 14:16'
    }
]

我想按日期排序(最近一次,或者更确切地说,最近是0指数)

我该怎么做?

更新

类似

arr.sort(function(a,b){
    return new Date(b.date) - new Date(a.date);
});

理论上应该工作,但是,我有一个问题,新的date()由于某种原因在数组中的某些项上返回'无效日期',例如:

arr.sort(function(a,b){
            console.log(b.date)
            console.log(new Date(b.date))
            return new Date(b.date) - new Date(a.date);
        });

我得到了记录:

09/01/2014 14:23
Mon Sep 01 2014 14:23:00 GMT+0100 (GMT Daylight Time)

23/07/2014 09:04
Invalid Date

23/07/2014 09:04
Invalid Date

09/01/2014 14:23
Mon Sep 01 2014 14:23:00 GMT+0100 (GMT Daylight Time)

我爱@Phrogz answer

arr.sort(function(a,b){
  // Turn your strings into dates, and then subtract them
  // to get a value that is either negative, positive, or zero.
  return new Date(b.date) - new Date(a.date);
});

这应该有用,请检查旧的IE浏览器,我认为它也应该在那里工作 http://jsfiddle.net/9t3Xq/

 arr.sort(function(a, b) {
    var valueA, valueB;

    var dates1 = a.date.split(" ");
    var dates2 = b.date.split(" ");

    var dates1YMD = dates1[0].split("/");
    var dates2YMD = dates2[0].split("/");

    var dates1HIS = dates1[1].split(":");
    var dates2HIS = dates2[1].split(":");

    valueA = new Date(dates1YMD[2], dates1YMD[1], dates1YMD[0], dates1HIS[0], dates1HIS[1]);
    valueB =  new Date(dates2YMD[2], dates2YMD[1], dates2YMD[0], dates2HIS[0], dates2HIS[1]);
    return valueB - valueA;
});
