aijs 对象排序

1.字典对象

function dictGetValue (value) {
    for (dictGetValueIndex in value)return value[dictGetValueIndex]
}
function dictGetKey (value) {
    for (dictGetKeyIndex in value)return dictGetKeyIndex
}

var dic = [{'小明': 40}, {'简单': 100}, {'幸福': 70}];


dic.sort(function(a,b){
    return dictGetValue(a)-dictGetValue(b)
});

for(i in dic){
    alert(dictGetKey(dic[i])+':'+dictGetValue(dic[i]))
}

2. 对象

```javascript

function Person(name,age) {
    this.name= name;
    this.age= age;
    this.toString = function () {
        return this.name+'::'+this.age
    }
}
var persons = [new Person('小明',40), new Person('简单',100), new Person('幸福',70)];
persons.sort(function(a,b){
    return a.age-b.age
});
for (i in persons) {
    alert(persons[i])
}
