  ajax error when loading base url but works when adding home/Index on the end

  Feb 04, 2019 04:02 PM|Quektis|LINK

  The base url for my project won't work without Home/Index on the end, it returns an ajax error. How can I ensure that if the base url is entered without Home/Index, that it will work without returning an error?

  public static void RegisterRoutes(RouteCollection routes)
      {
          routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
  
      routes.MapRoute(
              name: "Default",
              url: "{controller}/{action}/{id}",
              defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
          );
      }

  Ajax:

  "ajax": {
              "url": "../Home/GetTaskLog",
              "type": 'POST',
              "content-type": "application/json; charset=utf-8",
              "processData": false,
              "dataType": "json",
              "headers": "headers",
              "data": "window.JSON.stringify(obj)",
              //"headers": { "__RequestVerificationToken": $('input[name=__RequestVerificationToken]').val() },
              //"data": { "__RequestVerificationToken": $('input[name=__RequestVerificationToken]').val() },
              "traditional": true,
              "dataSrc": function (data) {
                  return JSON.parse(data);
              },
          },

  your ajax url is incorrect when you don't specify the full url for the hosting page. you should use the url helper:

   "url": "@Url.Action("GetTaskLog","Home")",

  In JavaScript with '/' you can go to the root of the application. So you can use this in mapping your URL for .ajax() method of jQuery. See the below code:

  "ajax": {
       "url": "/Home/GetTaskLog",
       //....

  this requires the site be deployed to the root.

  Hi Quektis,

  Quektis

  The base url for my project won't work without Home/Index on the end, it returns an ajax error. How can I ensure that if the base url is entered without Home/Index, that it will work without returning an error?

  Do you mean you delete this line:

  defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
  

  If so,the compiler does not recognize the URL according to the {controller}/{action}/{id} rules.

  id = UrlParameter.Optional can let id could null.

  So,../Home/GetTaskLog is not work.

  If you must delete default line, you could modify the url in RouteConfig,like:

  url: "{controller}/{action}/{id}",
  //defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },

  or 

  url: "{controller}/{action}/{id}",
  defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },

  More details about route,you could refer to:

  https://www.asp.net/mvc/overview/controllers-and-routing

  https://docs.microsoft.com/en-us/aspnet/mvc/overview/older-versions-1/controllers-and-routing/creating-a-route-constraint-cs

  @bruce:  The ajax is used to retrieve data from a database and to populate a dataTable table. In this case GetTaskLog is refering to a function that retrieves data from a database. I can confirm that it works, but only when adding home/index to the end of the url. I am still getting an ajax error with the above code

  @yogyiyogi: Thanks, that still doesn't work though.

  @Yuki tao: Thanks for the input but the changes didn't make any difference, I am still getting an ajax error when loading the base url.

  Hi Quektis,

  Quektis

  but only when adding home/index to the end of the url.

  Actually,I can't quite understand this mean.

  Is my previous understanding correct?

  And what is your ajax  error message?

  Best Regards
