贴一段jQuery对js对象及数组的操作：增删改查的代码。

复制代码 代码如下:
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 DeleteWork(guid) {
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='DeleteWork(\"" + val.Id + "\")'>×</a></span>";
});
$("#tdWorkList").html(html);
}
function AddWork() {
if(CheckIsNull("workaddress","工作地址不能为空")
&& CheckIsNull("worklevel", "职责不能为空")
&& CheckIsNull("WorkBegin", "工作开始日期不能为空")
&& CheckIsNull("WorkLeave", "工作结束日期不能为空")
)
{
var isok = true;
$.each(WorkList, function (key, val) {
if (val.DepartmentName == $("#workaddress").val()
&& val.Title == $("#worklevel").val()
&& val.BeginTime == $("#WorkBegin").val()
&& val.EndTime == $("#WorkLeave").val()
)
{
alert("存在相同的工作经历。"); isok= false;
}
});
if (isok){
var onework = new WorkEx($("#workaddress").val(), $("#worklevel").val(),
$("#WorkBegin").val(), $("#WorkLeave").val())
WorkList.push(onework);
// <span class="add_work_unit">四川省乐天区某某制药厂<a href="#">×</a></span>
ShowWork();
}
}
}
