jQuery Ajax请求在Asp.net MVC 4中给移动设备带来了错误

I am using jquery 1.11.1 with Asp.net MVC I am requesting a $.ajax request to my MVC Controller Action and it is working fine on desktop but giving error on mobile version

我正在使用带有Asp.net MVC的jquery 1.11.1我正在向我的MVC Controller Action请求一个$ .ajax请求它在桌面上工作正常但在移动版本上出错

My jQuery Ajax request is as follows:

我的jQuery Ajax请求如下:

$.ajax({
       method: 'GET',
       url: ajaxurl + 'GetListingByAjax',
       contentType: 'application/json; charset=utf-8',
       data: JSON.stringify({
           pagenumber: pageno,
           currenturl: location.href
       }),
       dataType: 'json',
       success: function (data) {
           if (data.length > 0) {
              $('#LoadMoreListings').show();
              var FullHTML = GetListingHTML(data);
              $('#loading').remove();               
              pageno++;
           }
           else {
              $('#LoadMoreListings').hide();
              $('#loading').text('No more listings to display');
           }
       },
       error: function (a,b,c) {
            alert('Exeception Description : '+c);
       }
   });

And My Controller Action is

我的控制器动作是

public JsonResult GetListingByAjax(int pagenumber, string currenturl = "")
{
    var ListingItemsList = new Listing().GetListingAjax(currenturl, pagenumber, 20, 0);
    return Json(ListingItemsList, JsonRequestBehavior.AllowGet);
}

This is working fine on desktop and when I run it on mobile it gives me Internal Server Error then I checked the response in Chrome Emulator then it shows following error

这在桌面上工作正常,当我在移动设备上运行时它会给我内部服务器错误,然后我在Chrome模拟器中检查了响应然后它显示以下错误

The parameters dictionary contains a null entry for parameter 'pagenumber' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.JsonResult GetListingAjax(Int32, System.String)

参数字典包含方法'System.Web.Mvc.JsonResult GetListingAjax(Int32,System.String)的非可空类型'System.Int32'的参数'pagenumber'的空条目

Then I tried by changing method GET to POST but the error on mobile was same and on desktop it was fine

然后我尝试将方法GET更改为POST,但移动设备上的错误是相同的,在桌面上它很好

Can anyone help me please am I doing something in wrong way or i need to add anything extra in this code to be run on mobile

任何人都可以帮助我,我是以错误的方式做某事,或者我需要在此代码中添加额外的东西以便在移动设备上运行

Please help me out thanks in advance

请提前帮助我

You are missing the pagenumber parameter in your ajax URL:

您缺少ajax URL中的pagenumber参数:

url: ajaxurl + 'GetListingByAjax',

should be something like

应该是这样的

url: ajaxurl + 'GetListingByAjax/2',

In that way the controller gets to make use of the parameter pagenumber you've told it to require.

通过这种方式,控制器可以使用您告诉它需要的参数pagenumber。
