You cannot set server side values with Javascript. You could bind these values to input fields like textboxes or hidden fields and then use Javascript to modify these values of these input fields.
您不能使用 Javascript 设置服务器端值。您可以将这些值绑定到文本框或隐藏字段等输入字段，然后使用 Javascript 修改这些输入字段的这些值。

You can't execute a server-side code like that in JavaScript.
你不能像 JavaScript 那样执行服务器端代码。
You need to somehow post the updated values back to the server to process them.
您需要以某种方式将更新后的值发布回服务器以处理它们。
Take a look at KnockoutJS, it makes things like this very easy. Basically, you will just serialize your model class on the client side to a JavaScript object, work with it until you decide to save it back and then you send it to the server as JSON, which will allow you to have an action method like this
看看KnockoutJS，它使这样的事情变得非常容易。基本上，您只需将客户端的模型类序列化为 JavaScript 对象，使用它直到您决定将其保存回来，然后将其作为 JSON 发送到服务器，这将允许您拥有这样的操作方法
public ActionResult UpdateEmployee(Employee employee)
{
// Update the database...
//
}
