js對象數組排序

//數組排序例子
var arr = [{name: "zlw", age: 24}, {name: "wlz", age: 25}];

//降序
var compare = function (obj1, obj2) {
    var val1 = obj1.name;
    var val2 = obj2.name;
    if (val1 < val2) {
        return -1;
    } else if (val1 > val2) {
        return 1;
    } else {
        return 0;
    }            
} 

arr.sort(compare);
console.log(arr);
