    var dic = {
        2: {"score": 20},
        1: {"score": 25},
        3: {"score": 15},
        4: {"score": 60},
    }

    console.log("输出最初的字典元素: "); 
    for(var key in dic){
        console.log("key: " + key + " ,value: " + dic[key]["score"]);
    }

    console.log("字典元素按key值排序: ");
    var res = Object.keys(dic).sort(); 
    for(var key in res){
        console.log("key: " + res[key] + " ,value: " + dic[res[key]]["score"]);
    }

    console.log("字典元素按value值排序: ");
    var res2 = Object.keys(dic).sort(function(a,b){ return dic[a]["score"]-dic[b]["score"];             });
    for(var key in res2){
        console.log("key: " + res2[key] + " ,value: " + dic[res2[key]]["score"]);
    }
