c# - How to pass JSON string via Angular $http using a variable instead of function(param)? -


i have json object so:

var newcontact = {"contact_name":"joe","contact_cell_phone":"4651354"}

and need pass through c# asp backend using angular $http.post such as:

$scope.add = function (newcontact) {          // passing in string variable "newcontact_string", not function param "newcontact"         var newcontract_string = json.stringify(newcontact);          $http             .post('default.aspx/adddb_contact', { newcontact_string: newcontact_string })             .success(function (data) {                 console.log("new contact added id: " + data.d);             })             .error(function () {                 console.log("an error occurred adding new contact.");             });     };

however, hit error in js console, referring line of code:

referenceerror: newcontact_string not defined >> $http.post('default.aspx/adddb_contact', { newcontact_string: newcontact_string })

my c# backend code never reached:

[webmethod] public static object adddb_contact(string newcontact_string) {     return newcontact_string; }

perhaps syntax error? how go ajaxing angular way?

you have typo.

you declare var newcontract_string = json.stringify(newcontact);

but pass newcontact_string.

you need: { newcontact_string: newcontract_string }
