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;
});

array.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;
});

As far as I know you will have to make your own sorting function.
If you can store it in a object than defining a function like in the previous answer will do the job.
Refer Sort array of objects

Here is a generic function 

function arraySort(pArray)
{
pArray.sort(
  function(a,b)
  {
    var len=a.length;
    for (var i=0;i<len;i++)
    {
      if (a[i]>b[i]) return 1;
      else if (a[i]<b[i]) return -1;
    }
    return 0;
  }
);
}
