具有Codeigniter表单验证的AngularJs

Question

我只是对angularjs的新手我更多关于jquery而且我只是尝试在post请求中使用angular与ajax的工作方式相同。但当我看到我的console.log（）时，我看到了一个问题，我的验证输出有一个html标签

输出中

** CONTROLLER（codeigniter）**

public function auth(){
    $obj = json_decode(file_get_contents('php://input'));
    $_POST = json_decode(file_get_contents('php://input'),true);
    $this->form_validation->set_rules('name','Name','required|is_unique[users.name]');
    $this->form_validation->set_rules('password','Password','required');
    $this->form_validation->set_rules('cpassword','Confirm Password','required');

    if($this->form_validation->run()==FALSE){
        echo json_encode(validation_errors());
    }else{
        echo json_encode("no error");
    }
}

MY ANGULARJS

<script type="text/javascript">
var app = angular.module('app', []);
var base_url = window.location.origin+"/";

app.controller('myCtrl', function($scope,$http) {
$scope.message = "";
$scope.formData = {}
$scope.submit = function(){
    var regdata = {
        url: base_url+"main/auth",
        method: "POST",
        data: { 
            name: $scope.name,
            password: $scope.password,
            cpassword: $scope.cpassword 
        },
        headers: {'Content-Type': 'application/json'},


    }

    $http(regdata).then(function successCallback(response) {
            $scope.message = response.data;
            console.log($scope.message);

      }, function errorCallback(response) {
        alert('Something Went Wrong! :( ');
      });
}
});
</script>
