Javascript多维数组按数字顺序排序 [英] Javascript multidimentional array sorting by numerical order

问题描述

我有一个二维数组，需要对它进行数字排序.这是数组的示例:

I have a two dimensional array that I need to sort numerically. Here is a sample of the array:

   [0]    [1]
    3     320
    55B   250
    26    100
    55A   260
    56    310
    89    420

我需要按[0]值进行数字排序.值存储为字符串.我已经弄清楚了如何按字母和数字顺序对数组进行排序，但是由于偶尔会出现A和B，因此我无法弄清楚如何对数组进行排序.

I need to order numerically by the [0] values. The values are stored as strings. I have figured how to sort arrays alphabetically and numerically but I can't figure out how to order this array because of the occasional A and B.

推荐答案

parseInt方法将忽略数字之后的任何字符串字符，从而删除A和B.

The parseInt method will ignore any string characters after the number, removing the A's and B's.

arr.sort(function(rowA, rowB){
    var a = parseInt(rowA[0], 10);
    var b = parseInt(rowB[0], 10);

    if (a > b)
        return 1;
    else if (a < b)
        return -1;
    return 0;
});
