首先是用JS实现动态新增一行、删除指定行的操作，然后利用AJAX的PageMethod方式，调用后台代码实现数据提取，然后把数据装载到公司实体对象与部门实体对象集合中，提交到数据库（这部分没有去实现，不用多说了，大家都会）。其中需要注意几个方面
、必须在 ScriptManager 设置 EnablePageMethods="true"，这样才能使用PageMethod方式
、在JS中调用的服务端函数必须加上[System.Web.Services.WebMethod]
其它的代码太简单，就不用一一说明。声明：本网页内容旨在传播知识，若有侵权等问题请及时与本网联系，我们将在第一时间删除处理。TEL:177 7030 7066 E-MAIL:11247931@qq.com
