Discover the process of selecting an item from a list and viewing it on a separate page with the help of AngularJS and Ionic technology

I am struggling with creating a list of items that, when clicked, should take me to the corresponding post. Despite trying to use ng-click in the header, I suspect there is an issue with the route not functioning properly.

As part of my testing process, I have included a line where clicking on "VIEW" should trigger the function mentioned earlier. My assumption is that the problem may be related to how I've defined states in app.js and how they are implemented in $state.go.

Any assistance would be greatly appreciated. Thank you!

Main List HTML:

<ion-view ng-controller="NavCtrl"> 
    <div class="container posts-page">
          <div class="post row" ng-repeat="(postId, post) in posts">

    <a ng-click="view()">VIEW</a> <!-- Clicking VIEW doesn't do anything-->


The JS File: using 'tab.view' isn't effective.

    $scope.view = function() {
      $state.go('tab.posts.view', {postId: postId});
    };


The App.js State File:

.state('tab.posts', {
  url: '/posts',
  views: {
    'tab-posts': {
      templateUrl: 'templates/tab-posts.html',
      controller: 'PostsCtrl'

.state('tab.posts.view', {
  url: '/:postId',
  views: {
    'tab-posts':{
      templateUrl: 'templates/tab-showpost.html',
      controller: 'PostViewCtrl'

Answer №1

If you refer to this interactive plunker, it demonstrates the steps on HOW TO achieve the desired outcome:

.state('tab.posts', {
  url: '/posts',
  views: {
    'tab-posts': {
      templateUrl: 'tab-posts.html',
      controller: 'PostsCtrl'
    },
  }
})
.state('tab.posts.view', {
  url: '/:postId',
  views: {
    // in this situation, instead of using
    // 'tab-posts':{
    // we need to employ
    'tab-posts@tab':{
      templateUrl: 'tab-showpost.html',
      controller: 'PostViewCtrl'
    }

As illustrated in the code snippet above, the issue at hand is that absolute view naming must be utilized:

In essence, each view is assigned an absolute name following a specific format of viewname@statename, where the viewname corresponds to the directive used and the state name represents the state's absolute name (e.g., contact.item). It is also feasible to use absolute syntax for view names.

Therefore, to target the view under the state tab named tab-posts, absolute naming like 'tab-posts@tab' should be applied.

Additionally, either passing the postId into the view() function or utilizing ui-sref directly is recommended:

<a ng-click="view(postId)">VIEW</a>
<a ui-sref="tab.posts.view({postId: postId})">VIEW</a>

To ensure completeness, here is an update view function that accepts the post id:

$scope.view = function(postId) {
    $state.go('tab.posts.view', {postId: postId});
};
