推荐答案

您需要使用带有JavaScript来做到这一点;我会建议使用jQuery。此外，把下拉菜单的形式，获取和控制器/动作URL的行动方法。然后设置click事件发布的形式。

You'll need to do this with Javascript; I would recommend using jquery. Also, put the dropdown in a form, method of get and action of the controller/action URL. Then set the click event to post the form.

所以，你的HTML将是这样的：

So, your HTML will be something like:

<form id="myForm" action="/Controller/Action" method="get">
    <select id="mySelect">...</select>
</form>

和jQuery中是这样的：

And in jquery something like:

$('#mySelect').change(function() { $('#myForm').submit(); });

请注意，你可以使用的Html.Form（）辅助函数来创建表单。另外，我建议有一个提交表单，您可以用JavaScript隐藏按钮。然后让JS禁用谁仍然让人有一种方式来提交表单。

Note you can use the Html.Form() helper to create the form. Also, I'd recommend having a submit button on the form, which you can hide with javascript. Then people who have JS disabled still have a way to submit the form.
