Detailed explanation of the steps for Jquery to operate js arrays and objects

var WorkList = new Array();//数组对象

//下面是自己定义的实体

function WorkEx(depart, title, begintime, endtime) {

    this.SId = 0;

    this.Id = -(WorkList.length+1);

    this.DepartmentName = depart;

    this.Title = title;

    this.BeginTime = begintime;

    this.EndTime = endtime;

    this.Description = "";

    this.Enable = 0;

    return this;

}

function

Delete

      WorkList = $.grep(WorkList, function (val, key) {

          return val.Id != guid;

    });

      ShowWork();

}

function ShowWork() {

    var html = "";

    $.each(WorkList, function (key, val) {

        html = html + " <span class=\"add_work_unit\">" + val.DepartmentName + ":" + val.Title

            + ",任职时间：" + GetJsDate(val.BeginTime) + "到" + GetJsDate(val.EndTime) + "<a href=\"#\"

onclick

    });

    $("#tdWorkList").html(html);
