【Javascript 项目代码】Home Care -- 类，封装性, 单链表排序 -- 2

思想：

创建三个类，一个Boss类，管理Worker的分配，统计worker和Task的个数。

Worker类，管理这个worker自己的Task。

Task类。

//Boss类
function Boss(){

    this.workerList = new Array();
    this.totalWorker = 0;
    this.totalTask = 0;
}

Boss.prototype = {

    constructor: Boss,
    //添加worker，并且使用单链表排序
    this.addWorker_sorted : function(head, worker){
    
        var cur = head;
        var flag = false;

        this.totalTask++;

        while(cur.next != null){

                cur.next.total = 1;
                break;
            }else if(parseInt(cur.next.workerNo,10) == parseInt(worker.workerNo,10)){
