Question

What is the best way to apply index-based filtering in Angular JS?

I am working on a tab system using ng-repeat to display tabs and content, but I'm facing some challenges in making it work seamlessly.

Below are the tabs being generated:

<ul class="job-title-list">
     <li ng-repeat="tab in tabBlocks">
        <a href="javascript:;" ng-click="activeTab($index)">dummy content</a>
     </li>
</ul>

And here is the corresponding content for each tab:

<div ng-repeat="content in contentBlocks">
    <p>more dummy content</p>
</div>

Additionally, I have a function that sets the selected tab index:

$scope.activeTab = function(i) {

   $scope.selectedTab = i
   console.log($scope.selectedTab)

}

I have been exploring options like ng-show, ng-switch, and ng-if to toggle the visibility of content based on the selected tab, but I haven't made much progress. Any suggestions or guidance would be greatly appreciated!

Thank you in advance!

If you want to utilize the tabset feature with bootstrap JS, you can follow this approach:

<tabset>
<tab ng-repeat="tab in tabs" heading="{{tab.title}}" active="tab.active" disabled="tab.disabled" id="{{tab.href}}">
 <div ng-include="tab.href"></div>
</tab>
</tabset>

After that, use ng-template to insert your code as shown below.

<script type="text/ng-template" id="tab.href">
<div>
 Insert your content here
</div>

Ensure that the tab id matches the ng-include to properly display your content.

Create a unique ng-template for each of your tabs as needed.

Make sure to keep a record of the tab index that was clicked and display or modify content accordingly.

To solve your issue, simply update the div where your content is being repeated with this code snippet:

<div ng-show="$index==currentTab" ng-repeat="item in itemBlocks">
<p>additional example text</p>
</div>

Exploring a new method to integrate the bootstrap tab feature with Angular, I managed to create a solution that eliminates the dependency on bootstrap.js and similar plugins. The final result exceeded my expectations.

Here is the HTML code snippet:

<ul class="nav nav-tabs" data-ng-controller="NavigationCtrl">
    <li data-ng-repeat="tab in tabs"
        data-ng-class="{'active': activeTab === tab }">
        <a ng-click="go(tab)" href="">{{ tab.title }}</a>
    </li>
</ul>

<div class="tab-content" data-ng-controller="NavigationCtrl">
    <div data-ng-repeat="tab in tabs" class="tab-pane"
         data-ng-class="{'active': activeTab === tab }" id="content">
         <div data-ng-view></div>
    </div>
</div>

The implementation requires a navigation controller, defined as follows:

app.controller("NavigationCtrl", ["$scope", "$location", function ($scope, $location) {

    // Define all tabs along with their respective routes
    $scope.tabs = [
        { id: 'content', title: 'random content', route: '/content' },
        { id: 'dialog', title: 'dialog', route: '/dialog' },
        { id: 'form', title: 'some form', route: '/form' },
        { id: 'grid', title: 'some grids', route: '/grid' }
    ];

    // Set the initial active tab
    $scope.activeTab = $scope.tabs[0];

    // Function to retrieve tab object based on route
    var tabByRoute = function (route) {
        for (var i = 0; i < $scope.tabs.length; i++) {
            if ($scope.tabs[i].route === route) {
                return $scope.tabs[i];
            }
        }

        return $scope.tabs[0];
    };

    $scope.go = function (tab) {
        $location.path(tab.route);
    };

    // Event triggered when path changes within the application
    $scope.$on("$locationChangeSuccess", function () {
        $scope.activeTab = tabByRoute($location.path());
    });
}]);

Feel free to utilize this solution for your projects.

            }
        }

        return $scope.tabs[0];
    };

    $scope.go = function (tab) {

    };

    // Event triggered when path changes within the application
    $scope.$on("$locationChangeSuccess", function () {
        $scope.activeTab = tabByRoute($location.path());
    });
}]);
