如何在javascript中对多维数组进行排序

问题描述

我有一个数组如下

var arry = [ [1, "Convention Hall", "Mumbai", 10, "XYZ Company"],
             [2, "Auditorium", "Delhi", 10, "ABC Company"],
             [3, "CenterHall", "Bangalore", 10, "ZZZ Company"],
            ....
            ]

我想根据数组的第三项按字母顺序对数组进行排序，即 arry[n][2]

I want to sort the array alphabetically based on the third item of array i.e arry[n][2]

如何做到这一点.

您可以使用 arry.sort().默认为字母数字和升序.

You can use the arry.sort(). The default is alphanumeric and ascending.

那就是:

var arry = [ [1, "Convention Hall", "Dangalore", 10, "XYZ Company"],
             [2, "Auditorium", "Belhi", 10, "ABC Company"],
             [3, "CenterHall", "Aumbai", 10, "ZZZ Company"],
            ];
var x =arry.sort(function(a,b){ return a[2] > b[2] ? 1 : -1; });
alert(x);
