javascript - .net mvc 4 application - call from ajax to a function in controller -

i'm creating mvc 4 application call function in controller js file using ajax.

when call function ajax, calling respective function properly. neither success nor error function not firing . me out correct mistake?

i read data database convert json format , write .js file , thereafter success function fired off. me solve this. in advance.

here code.

  $.ajax({         //url: '@url.action("getjsondata","home")',         url: "home/getjsonhugedata1",         //data: "{}",         type: "get",         //contenttype: 'application/json',         //datatype: "json",         success: function () {             alert();             alert('success getjsonhugedata');             loaddata(data);         },         error:function(){             alert('error');         }     }); 

controller:

public jsonresult getjsonhugedata()     {         var users = getusershugedata();         string json = "var datasource=";         json += jsonconvert.serializeobject(users.toarray());         system.io.file.writealltext(server.mappath("/scripts/newdata.js"), json);         return json(users, jsonrequestbehavior.allowget);       }    private list<usermodel> getusershugedata()     {         var userslist = new list<usermodel>();         usermodel user;          list<dummydata> data = new list<dummydata>();          using (database1entities dataentity = new database1entities())         {             data = dataentity.dummydatas.tolist();         }          (int = 0; < data.count; i++)         {             user = new usermodel             {                 id = data[i].id,                 productname = data[i].productname,                 revenue = data[i].revenue,                 inyear = data[i].inyear.year             };             userslist.add(user);         }      } 

i believe browser block file downloaded via ajax, because javascript cannot interact disk. if want working, have using form post.

@using (html.beginform("action", "controller", formmethod.post, new { id = "downloadform" })) {     ... form data here if had any...     <button type="submit">download</button> } 

you return filestreamresult contents of file downloaded.

public actionresult action(formmodel model) {     // work data file , return file result browser.     return new filestreamresult(new memorystream(filedata), "text/csv") // set document type valid file     {         filedownloadname = "users.csv"     }; }
