Angular disrupts the functionality of jQuery slideshow

While working on this template, I encountered issues with the functionality after integrating Angular into the application. Although I managed to fix most of them, I'm facing difficulty getting the slideshow to function properly.

Here is the HTML code:

<!doctype html>
<!--[if IE 9 ]><html class="ie9" lang="en"><![endif]-->
<!--[if (gt IE 9)|!(IE)]><!--><html lang="en"><!--<![endif]-->
<head>
    <link rel="icon" type="image/ico" href="images/fav.ico">
    <!--stylesheet include-->
    <link rel="stylesheet" type="text/css" media="all" href="css/bootstrap.min.css">
    <link rel="stylesheet" type="text/css" media="all" href="css/camera.css">
    <link rel="stylesheet" type="text/css" media="all" href="css/owl.carousel.css">
    <link rel="stylesheet" type="text/css" media="all" href="css/owl.transitions.css">
    <link rel="stylesheet" type="text/css" media="all" href="css/jquery.custom-scrollbar.css">
    <link rel="stylesheet" type="text/css" media="all" href="css/style.css">
    <link rel="stylesheet" type="text/css" media="all" href="css/lightbox.css">
    <!--font include-->
    <link href="css/font-awesome.min.css" rel="stylesheet">
</head>
<body ng-app="app">
<div class="camera_wrap m_bottom_0" ng-controller="slideShowCtrl" ng-show="slideShow()">
    ...
</div>

<div ng-view></div>

<script src="js/jquery-2.1.4.js"></script>
...
<script src="app/filters.js"></script>

</body>
</html>

This is the controller I am using:

controllers.slideShowCtrl = function($scope, $location){
    $scope.slideShow = function(){
        if($location.url() == '/' || $location.url() == '/home'){
            $scope.slideShowView = true;
            return true;
        }else{
            $scope.slideShowView = false;
            return false;
        }
    }
}

Below is the jQuery code for creating the slideshow:

// camera slideshow
(function(){
    var cs = $('.camera_wrap');
    if(cs.length){
        ...
    }
})();

The issue arises when I navigate through the pages and return to the home page (#/home) – sometimes the slider breaks, sometimes it doesn't, and occasionally it fixes itself. Here are screenshots illustrating the problem: https://i.sstatic.net/OYzmf.png and https://i.sstatic.net/P949p.png.

If more code snippets are required for better understanding, please let me know. Thank you for your assistance.

When integrating a JQ slideshow into an Angular view, it is important to initialize it each time the view is accessed. This is necessary because when the view or route changes, the slideshow may be removed from the DOM, resulting in the loss of content and the instance of the slideshow.

The issue arises when, upon first load or reload (F5), the slider appears fine and functions correctly.

It works initially because the slideshow is properly initialized.

However, after navigating through pages and returning to the home (#/home) page, the slider may sometimes break, sometimes remain intact, or sometimes fix itself.

This inconsistency occurs due to improper initialization of the slide when it is discarded from the DOM during route/view changes.

To ensure proper functioning, simply re-initiate the slideshow immediately after the view has rendered.

// This workaround demonstrates the basic concept of handling angular with other DOM manipulations like JQ.
// Further research on DOM manipulation in Angular and using directives for a more robust solution is recommended.

controllers.slideShowCtrl = function($scope, $location, $timeout){
    // Function to check if home page is being viewed
    $scope.slideShow = function(){
        if($location.url() == '/' || $location.url() == '/home'){
            $scope.slideShowView = true;
            return true;
        } else {
            $scope.slideShowView = false;
            return false;
        }

        // Re-initiate slideshow after the condition returns true
        $scope.$watch(function () {
            return $scope.slideShow();
        }, function (isShow) {

            // Delaying slideshow initialization after view rendering
            $timeout(function () {
                if(isShow){
                    var cs = $('.camera_wrap');
                    if(cs.length){
                        // Slideshow initialization code here
                    }
                }
            }, 0)

        })
    }
}

P.S. Please note that without a live demo like Fiddle/Plunker, I have implemented some tricks to increase the chances of providing a working solution. Feel free to remove $timeout to test its efficacy.

To address this issue, I suggest developing a directive specifically for creating slideshows.

I encountered a similar problem when using the swiper slider. However, after implementing the directive, my issue was resolved.

Here is an example of a directive that you can use:


angular.module('app', [])
    .directive('cameraSlider', function($timeout) {
        return {
            restrict: 'AC',
            templateUrl: function(element, attrs) {
                return attrs.templateUrl || 'your_template_url.html'; 
            },
            link: function($scope, element, attrs) {
                $timeout(function() {
                    // Code for initializing camera slider
                }, 200);
            }
        };
});

Now, you can apply the camera-slider class to elements wrapped in the camera-wrap class.
