Create a customized template using the resolve feature in the $stateProvider

Take a look at this code snippet:

bank.config(function($stateProvider) {
  $stateProvider
    .state('main.bank', {
      url: '/',
      controller: 'BankCtrl',
      resolve: {
        money: function(bankResource) {
          return bankResource.getMoney();
      },
      templateUrl: 'bank/bank.html'
    });
});

In the above code, the bank.html template is rendered once the resolve function completes.

I am interested in displaying a specific template based on the outcome of my money function.

For instance:

If money returns an object with items, I would like to render bank.html

However, if money returns an empty object, then display empty-bank.html

How can I implement this functionality within my $stateProvider? Alternatively, would it be more appropriate to use a directive for this purpose?

Answer №1

To optimize your code structure, consider moving the resolve code to the parent controller. Create two child routes - one for bank.html and another for empty-bank.html. Route based on the resolve result, similar to this example:

.state('main', {
  url: '/',
  controller: 'MainCtrl',
  resolve: {
    money: function(bankResource) {
      return bankResource.getMoney();
  }
})
.state('main.bank', {
  url: '/blank',
  controller: 'BankCtrl',
  templateUrl: 'bank/bank.html'
})
.state('main.emptybank', {
  url: '/emptyblank',
  controller: 'EmptyBankCtrl',
  templateUrl: 'bank/empty-bank.html'
});

Inject the resolved data into your controller and transition to a new state based on the outcome.

Answer №2

To dynamically switch views in the index.html of your main state based on the money variable, follow these steps:

.state('main', {
  url: '/',
  controller: 'MainCtrl'
})

Within your MainCtrl, set the value of the money variable based on certain conditions:

$scope.money = "bank"

or

$scope.money = "emptybank"

In your index.html file, specify which view to display using AngularJS:

<div ng-view="{{$scope.money}}"></div>

Update your router as follows:

.state('main.bank', {
  url: '/bank',
  views: {
     bank: {
    controller: 'BankCtrl',
    templateUrl: 'bank/bank.html'
    },
    emptybank: {
    controller: 'EmptyBankCtrl',
    templateUrl: 'bank/emptybank.html'
    }
  }
})

If there are any syntax errors, please excuse them as I typed this from memory on my mobile device.

This solution should resolve your issue and enhance the AngularJS functionality in your application. Enjoy coding! :-)
