I am making an ionic + angularJs app, for Android to be specific. I don't know why, but in my so named homeController, whenever I tried to call a function to show me a $ionicModal, it gives me an error...

TypeError: Cannot read property 'show' of undefined at Scope.$scope.openModal (homeModule.js:18) at new (homeModule.js:59) at Object.invoke (ionic.bundle.js:11994) at $get.extend.instance (ionic.bundle.js:16247) at ionic.bundle.js:15502 at forEach (ionic.bundle.js:8155) at nodeLinkFn (ionic.bundle.js:15501) at positeLinkFn (ionic.bundle.js:14887) at publicLinkFn (ionic.bundle.js:14766) at IonicModule.controller.self.appendViewElement (ionic.bundle.js:47324)

My controller looks like this (the start of it):

app.controller('homeController', function($scope, $ionicPopup, $state, $ionicLoading, $rootScope, $ionicModal, mapFactory){
    // Load the modal from the given template URL
    $ionicModal.fromTemplateUrl('templates/loginModal.html', function($ionicModal) {
      $scope.modal = $ionicModal;
      console.log($scope.modal);
    }, {
      scope: $scope,
      animation: 'slide-in-up',
      backdropClickToClose: false,
      hardwareBackButtonClose: false,
      focusFirstInput: true
    });
    $scope.openModal = function() {
        $scope.modal.show();
    };
    $scope.closeModal = function() {
        $scope.modal.hide();
    };

I have tried already many different ways to make the modal open, the funny thing is, whenever I go to a new $state, and go back, it opens... But not when I refresh the page. Also, I did a console.log($scope.modal) to see if my variable was being set, and the result was:

ionic.Utils.inherit.child {focusFirstInput: true, unfocusOnHide: true, focusFirstDelay: 600, backdropClickToClose: false, hardwareBackButtonClose: false…}$el: JQLite[1]animation: "slide-in-up"backdropClickToClose: falseel: div.modal-backdropfocusFirstDelay: 600focusFirstInput: truehardwareBackButtonClose: falsemodalEl: ion-modal-view.modalscope: ChildScopeunfocusOnHide: trueviewType: "modal"__proto__: ionic.Utils.inherit.Surrogate 

Can anyone please help me on this one? Thanks in advance.

The error means $scope.modal was not created - you call to fromTemplateUrl isn't right. The second parameter is the modal options and you're passing a callback.

The documentation provides a good example.

In your case, the call to fromTemplateUrl should look more like this:

$ionicModal.fromTemplateUrl('templates/loginModal.html', {
  scope: $scope,
  animation: 'slide-in-up',
  backdropClickToClose: false,
  hardwareBackButtonClose: false,
  focusFirstInput: true
}).then(function(modal) {
  $scope.modal = modal;
  console.log($scope.modal);
});

I think i found the fix. I was trying to open the modal from inside a 'if' statement, as soon as i took it off from the 'if', it worked perfectly fine. Anyways, thank you Brad.
