解决方案

您可能被ASP假装为浏览器和服务器端代码中的存在"控件所迷惑.除非您将它们回发(使用页面回发或AJAX请求)，否则在浏览器中使用JavaScript进行的任何更改都不会在服务器上存在.如果您希望这些复选框状态更改在服务器上注册，则要么需要提交表单，要么需要在更改后发送AJAX请求来处理和更新数据模型.

解决方案

You are probably being fooled by ASP pretending that controls ''exist'' both in the browser and in your server-side code. Any changes you make with JavaScript in the browser don''t exist on the server unless you post them back (either with a page postback or an AJAX request). If you want those checkbox status changes to register on the server you either need to submit a form or you need to send an AJAX request when they are changed which you handle and update the data model.
