根据其属性值对JSON数组进行排序

Question

这是我获得的JSON数组:

    [
        {
            "Name" : "Sachin",
            "Age"  : "41",
            "Team" : "Mumbai"
        },
        {
            "Name" : "Dravid",
            "Age"  : "42",
            "Team" : "Rajasthan"
        },
        {
            "Name" : "Yuvraj",
            "Age"  : "31",
            "Team" : "Bangalore"
        }
    ]

但是我需要通过"Age"属性对这个JSON数组desc进行排序.我想要的JSON数组应如下所示:

 [
    {
        "Name" : "Dravid",
        "Age"  : "42",
        "Team" : "Rajasthan"
    },
    {
        "Name" : "Sachin",
        "Age"  : "41",
        "Team" : "Mumbai"
    },
    {
        "Name" : "Yuvraj",
        "Age"  : "31",
        "Team" : "Bangalore"
    }
]

怎么做到这一点？

Answer 1

var a = [
    {
        "Name" : "Sachin",
        "Age"  : "41",
        "Team" : "Mumbai"
    },
    {
        "Name" : "Dravid",
        "Age"  : "42",
        "Team" : "Rajasthan"
    },
    {
        "Name" : "Yuvraj",
        "Age"  : "31",
        "Team" : "Bangalore"
    }
];

   a.sort(function(x,y){return y["Age"]-x["Age"]});
   console.log(a);
