Issues related to Angular button

As I embark on my journey of creating my very first Angular app, I've encountered a couple of stumbling blocks that have left me scratching my head in confusion. The issue arises when I try to include the following snippet within my template:

<button ng-hide="results.length === projects.length" ng-click="limit = limit +3; gotoBottom()">Show More</button>

Strangely, whenever this button is placed inside the template, the app refuses to load. However, if I paste it outside of the template, everything functions perfectly fine. Ideally, I would like to keep this button within the template. Can someone please shed some light on what might be going wrong?

In addition to resolving the loading issue, I am also facing difficulties with getting the button to scroll to the #footer div using the ng-click function as shown below:

$scope.gotoBottom = function() {
 $location.hash('footer');
 $anchorScroll();
};

To provide more context and clarity, I have created a Plunker showcasing my code, which can be accessed through the following link:

Answer №1

If you're referring to the 'template' in terms of the 'projects' template, here's what you should do:

Explanation:

The projects template should have only one main element, so I included a div to encompass your list of project and the 'show more' button.

<div>
  <div class="cards" ng-init="limit = 3">
    <div class="card" ng-repeat="project in projects | limitTo: limit as results">
      <div class="card-image">
        <img src="{{project.img}}" alt="{{project.name}}" />
      </div>
      <div class="card-copy">
        <h2>{{project.name}}</h2>
        <p>{{project.desc}}</p>
        <p><a href="{{project.url}}" target="_blank"><i class="fa fa-location-arrow"></i></a></p>
      </div>
    </div>
  </div>

  <button ng-hide="results.length === projects.length" ng-click="limit = limit +3; gotoBottom()">Show More</button>
  <div id="footer" name="footer"></div>
</div>

For automatic scrolling: inject $timeout service

Explanation:

You didn't have any div named footer, so I added one right below the 'show more' button and included a 100ms timeout. This ensures that after loading your 3 projects, it will scroll to the 'footer' div. Using $timeout is crucial because the projects need to be rendered before scrolling.

$scope.gotoBottom = function() {
  $timeout(function() {
    $location.hash('footer');
    $anchorScroll();
  }, 100);
};

Make the necessary change in projects.js file

angular.module('portfolioApp')
     .directive('projects', function() {
       return {
        templateUrl: 'projects.html',
        controller: 'mainCtrl',
        replace: false // do not remove directive tags
        };
    });

This adjustment should fix the issue. Plunker Link here
