javascript - Remove item from json file using angularjs -

i lost lot of time trying delete item json file

this json file

 {   "count": 3,   "data": [     {       "id": "1",       "raison": "abs",       "email": "abs@abs.com",       "tel": "021269999999"     },     {       "id": "3",       "raison": "podl",       "email": "abs@abs.com",       "tel": "021269999999"     }, {       "id": "5",       "raison": "ddms",       "email": "abs@abs.com",       "tel": "021269999999"     }   ] } 

in controller have

 $scope.deleterow = function() {   var _id = 3;           $scope.datas = json.stringify($scope.clients["data"]);           $scope.datas.splice(_id,1);        }; 

so gave _id want remove error $scope.datas.splice splice not function, tried simple file worked fine ["aaa","bob,"ccc"] using indexof() , splice in file json non :(

how in javascript can know/compare right id ?

so me , , lot .

you're getting error because splice() array method, while datas object string. might confusing slice() method, indeed defined strings.

so, cale_b pointed out, there no need stringify json object. leaving array give more functionality. example, if want remove second element in clients.data, can write:

$scope.clients["data"].splice(1, 1); 

and if wanted remove value based on id property, , not position of object in data array, can search using indexof() , find() methods, so:

$scope.clients["data"].splice(     $scope.clients["data"].indexof(         $scope.clients["data"].find(function(e) {             return e.id == 2; })), 1);
