如何在Jquery中列出项目并在服务器端获取它? [英] How do I do a list of items in Jquery and get it on server side?

问题描述

我正在尝试列出商品列表(例如客户的电话和家属)，例如，用户可以包括一些数字电话，然后删除其他数字电话(如果可能，可以对其进行编辑)，例如客户记录.

I'm trying to make a list of items (telephones and dependents for a customer), for example, the user could include some number phones and remove others (maybe edit them if it is possible), like a list inside the record of customer.

我想知道如何在客户端执行此操作并在服务器端获取列表? 是否有jquery插件或最佳实践呢?

I'd like to know how can I do it on client side and get the list in server side ? Is there a jquery plugin or a best pratice to do it?

P.S .:我正在使用ASP.Net MVC 2.

推荐答案

为了使我入门，我保留了这个示例，只需将适当的内容放入适当的文件中，然后对其进行编辑以匹配您的工作:

I keep this example around to get me started, just put the proper stuff in the proper files and edit it to match what you are doing:
