Linking to an external website using AngularJS for navigation

After developing my angular app, I included an array of menu items that are displayed in the template:

<nav id="menu">
  <ul>
    <li ng-repeat="i in menuItems" 
        ui-sref="{{ i | removeSpacesThenLowercase }}"
        ui-sref-active="active">{{ i }}</li>
  </ul>
</nav>

In my app.js file, I defined states using ui-router as follows:

.state('camera', {
  url: '/selection',
  templateUrl: '/views/selection.html',
  uiShade: 'light back',       
  back: 'intro'
})

While internal URLs function correctly, I encountered a challenge with external links such as:

.state('facebook', {
  url: 'https://www.facebook.com/'
})

It became clear that this approach was not effective. I began to consider the best method for including absolute external links in my template without creating separate arrays. How can I achieve this seamlessly?

Answer №1

Ui-sref is a reference to a state within your application, while your views represent different states as well. External sites do not fall under the category of states; they are simply links leading to outside sources.

Consider revising your menu generator to accommodate various types of menu entries:

  • State-based link (generated using ui-sref)
  • Standard link (created with href for external websites, emails, etc)

This way, you can populate your menuItems array with different objects effortlessly.

Answer №2

To solve this issue in my program, I utilized ng-if.

Here is an illustration of menu items:

     $scope.navItems = [{
        id: 1,
        title: 'Internal Link',
        href: null,
        sref: 'internal-state'
    },
    {
        id: 2,
        title: 'External Link',
        href: 'https:/google.co.uk',
        sref: null
    }];

Subsequently, in the HTML code, I applied ng-repeat to the <li> element and included both <a> tags for href and sref attributes, each controlled by an ng-if directive.

     <li ng-repeat="item in navItems">
         <a ng-if="item.sref" ui-sref="{{item.sref}}">{{ item.title }}</a>
         <a ng-if="item.href" href="{{item.href}}">{{ item.title }}</a>
     </li>

Answer №3

To solve this issue, I implemented a solution using an additional array for the external links along with an ng-click function.

$scope.openExternalLink = function(link) {
  if (confirm("Leaving the app, are you sure?")) {
    window.location = link;
  }
};
