数组排序自定义comparator()

function createComparator(){
    return function (object1,object2){
        if(object1 < object2){
            return -1;
        }else if(object1 > object2){
            return 1;
        }else{
            return 0;
        }
    }
}        

arr.sort(createComparator());
结果[0, 1, 1, 2, 3, 4, 5, 6, 8]

function createComparator(property){
    return function (object1,object2){
        var value1 = object1[property];
        var value2 = object2[property];
        if(value1 < value2 ){
            return 1;
        }else if(value1> value2 ){
            return -1;
        }else{
            return 0;
        }
    }
}   

arr.sort(createComparator("name"));
结果：[{name: "王五", age: 25},{name: "李四", age: 24},{name: "张三", age: 23}]
