javascript - Why Success or Error callback function not executing properly for $http.post in angularjs -


i'm trying communicate server using following code.

$scope.save = function () {         $scope.loading = true;          if ($scope.rolesetupmodel.roleid === "") {             // save             //$scope.loading = true;             $http.post('/securitymodule/rolesetup/addrole', json.stringify($scope.rolesetupmodel))                 .success(function (response) {                     $scope.loading = false;                     $('#addmodal').modal('hide');                     $scope.binddatatogrid();                     alert("success");                     toastr.success(response.message);                  })                 .error(function (response) {                     $scope.loading = false;                     alert("fail");                     toastr.error(response.message);                  });          }         else {             $http.post('/securitymodule/rolesetup/editrole',                     json.stringify(convarrtoobj($scope.rolesetupmodel)))                 .success(function (response) {                     $('#addmodal').modal('hide');                     $scope.loading = false;                     toastr.success(response.message);                     $scope.binddatatogrid();                 })                 .error(function (data) {                     $scope.loading = false;                     toastr.error(response.message);                 });          }     }

but i'm getting wired behavior. link being hit everytime, put debugger there, before completing request page getting kind of refreshed making model empty out entering success or error call back. know little promise object couldn't make sense. i'm doing wrong here?

my guess aren't binding $scope.save() ng-submit of <form> , have being triggered submit button, or have not followed docs forms

if form set with:

<form name="formscopename" ng-submit="save()" novalidate>

your $http should work fine. if have action set on form angular interprets want submit without ajax nd use default browser process. make sure action attribute doesn't exist.

also note there no reason stringify data yourself. done automatically $http internally. causing error perhaps

you can pass in $event protection , preventdefault. isn;t necessary however.

ng-submit="save($event)"

js

$scope.save = function (event){     event.preventdefult();      .....
