我有点停留在什么可能是一个常见的​​情况，但无法找到太多的解决办法的途径。

I'm a bit stuck on what is probably a common situation, but can't find much in the way of solutions.

我通过单个int参数的MVC控制器的方法，期待一个JSON响应回来。但问题是，参数，同时被填充在客户端，不被认可的在服务器端，并正在PTED为空间$ P $。

I'm passing a single int parameter to an MVC controller method, expecting a Json response back. Problem is, the parameter, while being populated at the client end, is not being recognised at the server end and is being interpreted as null.

这里的code：

function getBatches(p) {
$.ajax({
    type: "GET",
    data: "{'ProjectID': " + p + "}",
    url: "/Home/Batches",
    success: function(msg) {
        populateBatches(msg);
    }
});

}

对于p的值是一个整数。在服务器端，code是这样的：

The value for p is an integer. On the server end, the code looks like this:

[AcceptVerbs(HttpVerbs.Get)]
public JsonResult Batches(int ProjectID)
{
    return Json(TimeHelper.GetBatchesForProject(ProjectID));
}

我试着改变它稍微使服务器端int参数为空（即诠释？ProjectID ），但同样，这似乎并没有帮助。问题是某处翻译。想法？

I've tried altering it slightly so that the server-side int argument is nullable (i.e. int? ProjectID) but again, that doesn't appear to help. The problem is somewhere in the translation. Ideas?

推荐答案

数据必须是一个JavaScript对象字面：

data needs to be a Javascript object literal:

$.ajax({
    type: "GET",
    data: {ProjectID: p},
    url: "/Home/Batches",
    success: function(msg) {
        populateBatches(msg);
    }
});
