Guide to dynamically incorporating items from an array into the filter operation

How can I dynamically insert items from an array into the filter on the wizard.html page, so that when the templateUrl in the route is called, it can be rendered on the wizard.html page?

Controller

angular.module('tareasApp')
  .controller('NatureCtrl', function ($scope, $routeParams) {

    $scope.pageName = $routeParams.pageName;

    $scope.items =[
     {    
          href:'/sound-waves', 
          img:'waves.jpg', 
          video:'//www.youtube.com/watch?v=OG2eGVt6v2o',
          description:'Those Relaxing Sounds of Waves'
     },
     {    
          href:'/nature-relaxing-sound', 
          img:'ocean.jpg', 
          video:'//www.youtube.com/watch?v=SWR0GdC7_40',
          description:'Nature Sounds Relaxing Ocean Sounds'
     }
    ];  
 });

Page wizard.html

<div ng-controller="NatureCtrl">
 <div ng-repeat="item in items | filterBy: ['href']: ''Insert here , dynamically , the items of  array correspondent the accessed page" >

    <img ng-src="images/{{ item.img }}" width="400" height="200" >

    <p>{{item.description}}</p>

    <iframe width="655" height="400" ng-src="{{ item.video }}" frameborder="0" allowfullscreen></iframe>   
</div>
</div>

Route

angular.module('tareasApp')
  .config(function ($routeProvider, $locationProvider) {
    $locationProvider.html5Mode(true);
    $routeProvider

.when("/:pageName", {
     templateUrl: "views/wizard.html",
     controller: "NatureCtrl"
     })
      .otherwise({
        redirectTo: '/'
      });    
  });

The aim is to prevent duplicate pages with the same structure.

I am using angular-filter for basic tasks, but need help with configuring more complex tasks. Any alternative solutions are welcome as long as they solve the issue at hand.

Answer №1

It is recommended to select the appropriate item within the controller rather than in the template.

$scope.selectedItem = $scope.items.filter(function(item) {
  return item.href.indexOf($routeParams.pageName) === 1;
})[0];

Additionally, ensure that the ng-repeat directive is removed from the div.

Answer №2

After spending several days conducting experiments, I was able to successfully repair the filter as per my requirements.

The angular-filter simplifies the process of applying filters. I utilized the filterBy: ['href'] and included the pageName, which corresponds to the filename utilized in $routeParams.

<div ng-controller="NatureCtrl">
 <div ng-repeat="item in group = (group|filterBy: ['href']:pageName).slice(0, 1)">

    <img ng-src="images/{{ item.img }}" width="400" height="200" >

    <p>{{item.description}}</p>

    <iframe width="655" height="400" ng-src="{{ item.video }}" frameborder="0" allowfullscreen></iframe>   
</div>
</div>
