Is it possible to access a repeater variable within a JavaScript block in AngularJS?

Currently, I am working with AngularJS and attempting to achieve the following:

<ul>
  <li ng-repeat="thing in things">
    <a id="mybutton" href="link{{thing.Id}}">Click</a>
    <script type="text/javascript">
      $("#mybutton").click(function()
      {
        alert("Id: " + {{thing.Id}});
      });
    </script>
  </li>
</ul>

Unfortunately, both variations of alerting the Id value (using {{thing.Id}} or simply thing.Id) are resulting in errors ('unexpected token "{"' and 'thing is not defined'). Is there a way for me to properly access thing.Id within the scope of the repeater when executing JavaScript code?

On a practical note, my goal is to construct a URL based on this value along with some additional data using jQuery in JavaScript.

Answer №1

When using angular expressions in the `` tag, it won't work as intended since angular.js does not operate as a text-based template system. Instead, angular.js utilizes the DOM structure for its templates.

To accomplish what you are attempting without jQuery and solely relying on angular.js, refer to this functional example on jsFiddle: ``

The key is to implement an `ng-click` directive within your href:

<a ng-click="click(thing.id)">Click</a>

In addition, create a corresponding click-handler function in your controller:

$scope.click = function(thingId) {
    alert("Id: " + thingId);
    //$location.path('/some/path/'+thingId);
}

You have the option to use jQuery commands within the controller's function, but utilizing angular's `$location` service would be a more efficient choice: ``

Answer №2

The preferred method for storing data to an element is by using the syntax "data-id={{thing.id}}"

To retrieve the ID from within JavaScript, simply read it back using the data attribute.
