c# - Jquery callback function working only with debugger -


following jquery function : 

function login() {     debugger;     $.ajax({         type: "post",         url: '@url.action("login", "login")',         success: function (result) {             debugger;             if (result == "ok") {                 debugger;                 var url = $("#redirectto").val();                 location.href = url;             }         },         datatype: "json",         traditional: true     }); }

and following login function in controller : 

    [httppost]     public actionresult login()     {         int userid = userservice.loginuser("a@b.com", "abc");        // return view("../home/index");         return json("ok");     }

it works fine if debug jquery function. if remove debuggers, control not come in success portion of function. not sure wrong here.
tried replacing jquery function follows not working : 

function login() {         debugger;         $.ajax({             type: 'post',             url: '@url.action("login", "login")'         }).done(function (data) {             debugger;             var url = $("#redirectto").val();             location.href = url;         })           .fail(function () { alert("error"); })           .always(function () { alert("complete"); });     }

can me here?

it happens when server not returning proper josn.

first try

 $.ajax({     type: "post",     url: '@url.action("login", "login")',     success: function (result) {        console.log(result);     },  });

and check if output proper json or not,

you can try manually parsing json using $.parsejson()

hope helps.

php - Calling a template part from a post -
