推荐答案

自动回传Web窗体与一些JavaScript来实现。这不是外的现成的MVC，但是足够简单，做你自己的。

Auto-postback in Web Forms was accomplished with some JavaScript. This is not out-of-the-box in MVC, but simple enough to do on your own.

假设你有jQuery的：

Assuming you have jQuery:

$(document).ready(function() {
    $('#someCheckBox').change(function() {
        $('#yourFormId').submit();
    });
});

这是最接近的Web窗体怎么经典作品;基本上没有当与someCheckBox的ID的复选框被选中或取消选中，提交表单ID为yourFormId'。当然，你可以将其更改您的需求。

This is "closest" to how classic Web-Forms work; basically does "When a checkbox with the ID of 'someCheckBox' is checked or unchecked, submit the form with id 'yourFormId'. You can of course change this to your needs.

这是不包括外的开箱，由于大多数开发商倾向于AJAX调用，而不是全面的后背上，我会鼓励你，如果可以做到的。什么可能是更preferable是：

This wasn't included out-of-the-box due to most developers favoring AJAX calls instead of full-blown post-backs, which I would encourage you to do if possible. What might be more preferable is:

 $(document).ready(function() {
    $('#someCheckBox').change(function() {
        $.ajax(/*make an AJAX call*/);
    });
});
