阿贾克斯邮政参数始终是在MVC应用程序空 [英] Ajax Post Parameter is Always Null in MVC app

问题描述

我有一个简单的职位，在一个测试应用程序的工作原理

I have a simple post that works in a test app

控制器code

public ActionResult Delete(string Id)
{
    ... delete record ...
}

JavaScript的

JavaScript

function delAnnouncement(id) {
    $.ajax({
        type: "POST",
        url: "@Url.Action("Delete", "Announcements")",
        contentType: "application/json; charset=utf-8",
        data: JSON.stringify({ "Id": "03d23684-098a-4ae8-8fa2-7d9ce70d63ef" }), // Hard coded for testing
    success: function (data) {
        $("#AnnouncementsPH").replaceWith(data);
        }
    });        
}

我创建了一个简单的测试应用程序，它在那里工作。

I have created a simple test application and it works there.

我要寻找任何想法，以什么可以在现有的应用程序，总是会使传递给为空的ID存在。

I am looking for any ideas as to what may exist in the existing application that would always cause the id passed to be null.

东西我曾尝试：
路由信息是在两个应用程序之间的相同
他们都是安全的HTTPS网站。
预期对现有的网站工作的其他形式。这是只使用一个javascript后带参数的地方。这仅仅是列出的任何系统通知新的视图。
至于我可以告诉HTML是有效的
提琴手显示正在发送的数据。
我试图根本就很难code在ID一通

Things I have tried: Route Info is the same between the two applications They are both secure https websites. Other forms on the existing website work as expected. This is the only place a javascript post with a parameter is used. It is just the new view that lists any system announcements. As far as I can tell the HTML is valid Fiddler show the data is being sent. I have tried to simply hardcode in the Id to pass

我不知道这可能是导致后不工作。

I have no idea what could be causing the Post not to work.

感谢您的任何建议。

正如你所看到的标识被张贴到控制器，只是没有解析并提供给该方法的参数。

As you can see the Id is posted to the controller, just not parsed and supplied to the parameter in the method.

推荐答案

您可以添加喜欢的参数：

You can append the parameter like:

var targeturl = '@Url.Action("Test", "Controller")?id=' + ID;

$.ajax({
    url: targeturl,
    type: "GET",
    success: function(data) { },
    error: function (data) { }
});

或者你可以直接使用jQuery的ajax的数据参数：

Or you may use the jQuery ajax data parameter directly:

$.ajax({
  type: "POST",
  url: '@Url.Action("Test", "Controller")',
  data: { id: "your-id" }
})
  .done(function( msg ) {
    alert( "Data Saved: " + msg );
  });
