The importance of the loop's $index value

Within my coding project, there is an <input> tag that utilizes a ng-repeat directive.

  <input ng-repeat="table in tables track by $index" type="text" name="lastName" ng-model="user.$index">

I am interested in accessing the value of $index within this loop. Is this achievable?

Answer №1

Here is an example of how to display it:

{{$index}}

Example Link:

  <ul class="example-animate-container">
    <li class="animate-repeat" ng-repeat="item in items | filter:q as results">
      [{{$index + 1}}] {{item.name}} who is {{item.age}} years old.
    </li>
    <li class="animate-repeat" ng-if="results.length == 0">
      <strong>No results found...</strong>
    </li>
  </ul>

Answer №2

To make use of the $index variable within an AngularJS Expression, refer to the documentation for more information.AngularJS Expression Documentation.

For example:

<html ng-app="myApp">
  <head>
    <meta charset="utf-8>
    <title>AngularJS Expression Example</title>
    <script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.1/angular.min.js"></script>
    <script>
      var mod = angular.module('myApp', []);
      mod.controller('myCtrl', function ($scope){
        $scope.tables = ['One', 'Two', 'Three', 'Four', 'Five'];
      });
    </script>
  </head>
  <body ng-controller="myCtrl">
    <input ng-repeat="table in tables track by $index" type="text" name="lastName" value="{{$index}}">
  </body>
</html>
