Say you have a form that has values loaded from database. How do you initialize ng-model?

Example:

<input name="card[description]" ng-model="card.description" value="Visa-4242">

In my controller, $scope.card is undefined initially. Is there a way besides doing something like this?

$scope.card = {
  description: $('myinput').val()
}

    This is a common mistake in new Angular applications. You don’t want to write your values into your HTML on the server if you can avoid it. If fact, if you can get away from having your server render HTML entirely, all the better.

    Ideally, you want to send out your Angular HTML templates, then pull down your values via $http in JSON and put them in your scope.

    So if at all possible, do this:

    app.controller('MyController', function($scope, $http) {
    $http.get('/getCardInfo.php', function(data) {
       $scope.card = data;
    });
});

<input type="text" ng-model="card.description" />

    If you absolutely MUST render your values into your HTML from your server, you could put them in a global variable and access them with $window:

    In the header of your page you’d write out:

    <head>
   <script>
       window.card = { description: 'foo' };
   </script>
</head>

    And then in your controller you’d get it like so:

    app.controller('MyController', function($scope, $window) {
   $scope.card = $window.card;
});
