Append key value pair to angularjs object - angularjs

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>

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>
