rated 0 times [ 66] [ 3] / answers: 1 / hits: 31443 / 13 Years ago, tue, august 9, 2011, 12:00:00

I have a Multidimensional Array which has 3 columns (by using javascript)

[0] Number of vote

[1] Name of candidate

[2] Candidate Number

My array contents are:

1 | Peter | 3

1 | Mary  | 2

0 | David | 5

0 | John  | 4

0 | Billy | 1

How can I sort the array by [0] Number of vote and then [2] candidate number?

The result should be:

1 | Mary  | 2

1 | Peter | 3

0 | Billy | 1

0 | John  | 4

0 | David | 5

As previously said, you should use a custom sort function. Here's one that would do exactly what you want.

var arr = [];

arr[0] = [1, 'Peter', 3];

arr[1] = [1, 'Mary', 2];

arr[2] = [0, 'David', 5];

arr[3] = [0, 'John', 4];

arr[4] = [0, 'Billy', 1];



arr.sort(function (a,b) {

    if (a[0] < b[0]) return  1;

    if (a[0] > b[0]) return -1;

    if (a[2] > b[2]) return  1;

    if (a[2] < b[2]) return -1;

    return 0;

});
