重复的 根据内部数组中的值对外部数组进行排序，javascript在这里你会找到几个答案，就像我自己的
Duplicate of sort outer array based on values in inner array, javascript here you will find several answers, like my own
var arr = [.....]
arr.sort((function(index){
return function(a, b){
return (a[index] === b[index] ? 0 : (a[index] < b[index] ? -1 : 1));
};
})(2)); // 2 is the index
这对索引 2 进行排序
This sorts on index 2
