将键值对附加到 angularjs 对象

Question

I am getting json output from laravel 5.2 form request validation

My json output is:

{
    "title": [
        "The title field is required."
    ],
    "description": [
        "The description field is required."
    ],
    "address.city": [
        "City field is required"
    ]
}

Appending this output to object

var self = this;
self.error = {
    address: {}
};

var onFailure = function (response) {
    angular.forEach(response.data, function(value, key) {
        self.error[key] = value[0];
    });
};

I want to access this error object to my view, for "address.city", I can't access it using "ctrl.error.address.city", rest I can access

How to append object with key containing "."and show it in view?

Answer 1

Here is what you need. But its better not to have (.) in a property name. Instead you can use a underscore(_). Avoid using dot(.) as a chaaracter in property names.

 var myApp = angular.module('MyApp', []); myApp.controller('MyCtrl', function ($scope) { $scope.foo={}; $scope.foo['hello.There'] = "I'm foo!"; });

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app="MyApp" ng-controller="MyCtrl"> {{foo["hello.There"]}}<br /> <input type="text" ng-model="foo['hello.There']" /> </div>

Answer 2

if you know the key name then the only way you can access it is by [] .

You need to change your code to this

in your controller

myApp.controller('MyCtrl', function ($scope) {
 $scope.foo={};
$scope.foo "hi";
  });

in html

<div ng-app="MyApp" ng-controller="MyCtrl">
  <input type="text" ng-model="foo" /> </div>
