The ion-slide-box does not update after the active-slide has been changed using $index

I'm currently facing an issue with the controller that corresponds to this specific view.

.controller('MenuCtrl', ['$rootScope','$scope','$state','$timeout','$ionicSlideBoxDelegate',
function($rootScope, $scope, $state, $timeout, $ionicSlideBoxDelegate) {
    $scope.state = { detail: false, selected: 0 };
    $scope.stateSwitch = function() {
        $scope.state.detail = !$scope.state.detail;
        $timeout( function() { $ionicSlideBoxDelegate.update(); }, 50);
    }
    $scope.activateSlide = function($index) {
        $ionicSlideBoxDelegate.slide($index); 
    }

Below is the layout of the view in question.

<ion-view left-buttons="leftButtons">
        <ion-content class="has-header" has-tabs="true" ng-show="!state.detail">
        <div class="list menu-list">
            <a class="item" ng-repeat="item in items" ng-click="stateSwitch();activateSlide($index)">
                ...
            </a>
        </div>
    </ion-content>
    <ion-content class="has-header padding" has-tabs="true" ng-show="state.detail">
        <div class="menu-detail">
            <ion-slide-box does-continue="true" show-pager="false">
                <ion-slide ng-repeat="item in items">
                    ...
                </ion-slide>
            </ion-slide-box>
        </div>
    </ion-content>
</ion-view>

Clicking on a list item triggers the state.detail flag, switching the view to a detailed menu item page. When on the detailed page, users can navigate through items using the ion-slide-box.

The functionality works well when I don't specify a starting slide or choose a fixed index. However, upon trying to switch the active slide by passing the $index from the menu list, all slides collapse together and swipe functionality ceases to work.

This persists even after updating the slide box.

Am I mishandling the use of $index? Is there a better way to dynamically set the active slide? Any guidance would be greatly appreciated!

Answer №1

To activate a slide on your controller, make sure to use the variable "index" without the dollar sign in your function $scope.activateSlide.

Here is the code snippet that successfully worked for me:

HTML:

<h4 ng-repeat="type in view.menu.itens" ng-click="changeSlide($index)"></h4>

Controller:

$scope.changeSlide = function funChangeSlide(index) {
    $ionicSlideBoxDelegate.slide(index);
  }
