Asp。NET MVC Ajax-Post表单和Ajax-Get

I'm stuck, who can help me out? In my LogOn.aspx View I've login controls (Username, Password, RememberMe) inside a FORM tag:

我被困住了，谁能帮我?在我登录。aspx视图我有登录控件(用户名，密码，记住)在一个表单标签内:

<form id="loginform" method="post" action="/Account/LogOn/">

Below that, I've a hidden DIV with a OPTION dropdownlist and a confirm-button, with a onclick_event:

下面是一个隐藏的DIV，其中有一个选项下拉列表和一个确认按钮，还有一个onclick_event:

$.ajaxSetup({ cache: false });
$.ajax({
    type: "GET",
    url: "/Account/SetCompanyAndContinue",
    data: "{ 'id' : '1'}",
    contentType: "application/json; charset=utf-8",
    dataType: "json"
});

First, the user logs in. In jQuery, I post the login credentials via AJAX:

首先，用户登录。在jQuery中，我通过AJAX发布登录凭据:

var loginCred = new Object();
loginCred.Username = $('#userName').val();
loginCred.Password = $('#password').val();
loginCred.RememberMe = $('#rememberMe').checked;

var myJsonObject = JSON.stringify(loginCred);

$.ajaxSetup({ cache: false });
$.ajax({
    type: "POST",
    contentType: "application/json; charset=utf-8",
    url: "/Account/LogOnAjax/",
    data: myJsonObject,
    dataType: "json",
    success: function(data) {
        PostCredentialsSuccess(data);
    }
});

This POST works perfect. The breakpoint at the Controller Action is hit by the debugger and returns a JSON object of data. I put this JSON data into the OPTION dropdownlist. This Option Dropdownlist is then presented to the user. Then, when the user clicks the confirm-button, a second AJAX call is made:

这篇文章是完美的。控制器动作的断点被调试器击中并返回一个JSON数据对象。我将这个JSON数据放入选项下拉列表。然后将这个选项下拉列表呈现给用户。然后，当用户单击confirm-button时，进行第二次AJAX调用:

$.ajaxSetup({ cache: false });
$.ajax({
    type: "GET",
    url: "/Account/SetCompanyAndContinue",
    data: "{ 'id' : '1'}",
    contentType: "application/json; charset=utf-8",
    dataType: "json"
});

I would expect that the Controller Action named "SetCompanyAndContinue" gets hit:

我预计名为“SetCompanyAndContinue”的控制器操作会被命中:

    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult SetCompanyAndContinue(string id)
    {
        SessionAdapter.CustomerID = Convert.ToInt32(id);
        return null;
    }

But it ain't happening, instead, the default Controller Action get's hit the first time:

但是这并没有发生，相反，默认的控制器动作get在第一次命中:

    public ActionResult LogOn()
    {
        return View();
    }

BUT(!) the second time I click (the same) confirm-button the Controller Action finally hits [SetCompanyAndContinue].

但是(!)第二次单击(相同的)确认按钮时，控制器动作最终会点击[SetCompanyAndContinue]。

Can somebody tell me what I'm doing wrong? Many thanks in advance.

有人能告诉我我做错了什么吗?提前感谢。

you need to pass the data property as a javascript object not as a string

您需要将数据属性作为javascript对象传递，而不是作为字符串。

    $.ajax({ type: "GET",
    url: "/Account/SetCompanyAndContinue",
    data: ({id : 1}),
    contentType: "application/json; charset=utf-8", 
    dataType: "json" });

i recommend to use firebug to look at the actual HTTP Request that do get send from jQuery, that way tiny mistakes like this get obvious very quickly.

我建议使用firebug查看从jQuery发送的实际HTTP请求，这样，像这样的小错误很快就会显现出来。
