Turn off ion-slide when the application starts

Question

Turn off ion-slide when the application starts

Is there a way to prevent the slide feature from activating upon startup while still allowing me to set my own active page?

I've discovered this helpful snippet in HTML

<ion-slide-box active-page="disableSlide()">
    <ion-slide>Slide 1</ion-slide>
    <ion-slide ng-click="previous()">Slide 2</ion-slide>
    <ion-slide>Slide 3</ion-slide>
</ion-slide-box>

In JavaScript,

$scope.disableSlide = function(){
    $ionicSlideBoxDelegate.enableSlide(false);
    return 1;
}

$scope.previous = function(){
    $ionicSlideBoxDelegate.previous();
}

However, I encounter an error when clicking previous

Error: [$compile:nonassign] Expression 'disableSlide()' used with directive 'ionSlideBox' is non-assignable!

You can view the demo here.

I would appreciate any assistance, thank you.

Answer №1

<ion-slide-box> does not include an active-page attribute, as noted in the documentation.

The error you're experiencing is likely because you disabled the slider:

$ionicSlideBoxDelegate.enableSlide(false);

However, if you still want to change slides using ng-click, you can enable and disable the slider dynamically with a function like this:

function adjustSliderStatus()
{
    $scope.sliderEnabled = !$scope.sliderEnabled;
    $scope.sliderStatusText = $scope.sliderEnabled ? "Enabled" : "Disabled";

    $ionicSlideBoxDelegate.enableSlide($scope.sliderEnabled); 
}

$scope.sliderEnabled is a boolean property that determines the status of the slider.

To automatically adjust the slider status when the view is entered, you can use:

$scope.$on('$ionicView.enter', function(){
    adjustSliderStatus();
});

You can test this functionality in a Plunker. In the header, you can toggle the slider by calling adjustSliderStatus();:

<ion-nav-buttons side="left">

  <button class="button button-positive"
          ng-click="toggleStatus()">
    {{sliderStatusText}}
  </button>

</ion-nav-buttons>

Note: The slider starts off disabled initially.
