Asp.net mvc json


Asp.net mvc json



I am working on a mvc project, and having problem with json.

i have created a demo project with list of colors

    public JsonResult GetResult()     {         List<string> strList = new List<string>();         strList.Add("white");         strList.Add("blue");         strList.Add("black");         strList.Add("red");         strList.Add("orange");         strList.Add("green");         return this.Json(strList);     } 

i am able to get these on my page, but when i try to delete one color, that is when i send the following using jquery

function deleteItem(item) {         $.ajax({             type: "POST",             url: "/Home/Delete/white",             data: "{}",             contentType: "application/json; charset=utf-8",             success: ajaxCallSucceed,             dataType: "json",             failure: ajaxCallFailed         });     } 

the controler action

public JsonResult Delete(string Color) {}

Color always returns null, even if i have specified "/Home/Delete/white" in the url.

i know i am doing something wrong or missing something, but not able to find out what.

please can any one guide me in the right direction.

The simplest solution to your problem

Renaming your controller action parameter to id would do the trick just fine (in case your default route is defined as {controller}/{action}/{id}).

Don't forget about attributes

And don't forget to put the attribute on your action method, otherwise a web crawler would be able to delete all your colour entries..

Either use HttpPost or even better HttpDelete, because you do use Ajax request anyway, so you can issue a DELETE request..

2:


Try changing your url to:. "/Home/Delete?Color=white". The reason is that there isn't a route set up to handle a string called color, like you have.. Have a look at this for info on how to create a custom route that will handle your current url format.. http://www.asp.net/mvc/tutorials/creating-custom-routes-cs.


3:


Check your routes.

(Usually set in /global.asax.).


4:


try this above the default.
routes.MapRoute("Color", "{controller}/{action}/{color}", new { controller = "Home", action = "Index", Color = "" });
