JS multidimensional array Sorting is the focus of this article, before only talking about array ordering, now is the implementation of multidimensional data sorting, JS multidimensional array can be understood as a one-dimensional array, each element of it is an array object, and so on

//again a classic JS multidimensional data sorting method code bar
var temp = [
{ x:x-1, y:y-1, ct:5, d:0},
{ x:x , y:y-1, ct:2, d:1},
{ x:x+1, y:y-1, ct:7, D:2},
{ x:x+1, y:y, ct:3, d:3},
{ x:x+1, y:y+1, ct:0, D:4},
{ x:x, y:y+1, ct:1, D:5},
{ x:x-1, y:y+1, ct:6, d:6},
{ x:x-1, y :y, ct:4, D:7}
];
1, the first thing you give is not a multidimensional array, JS also has no multi-dimensional array of Concepts
2, simple application using bubble method is sufficient, the data can be larger when the partition method and Quick Sort Method
3, here gives the bubble method + callback function code, example for the array in ascending order of CT column
<script>
function cmp (a,b,c) {
if a[c] == B[c])
return 0;
return a[c] > b[c] ? 1:-1;
}
for (I=0;i <temp.length-1;i++)
for (J=i;j <temp.length;j++)
if (CMP (temp[i],temp[j], "CT") > 0) {
c = Temp[i]
Temp[i] = Temp[j]
TEMP[J] = C
}
