In this tutorial we will create a Remove Array Element Using AngularJS. This code will automatically remove an array value when the user click the delete button. The code itself use a angular directives that can remove an array value when the array index is set as a parameter in the selectMember() after clicking the button, then it will delete the stored array index in the deleteMember(). This a user-friendly program feel free to modify and use it to your system.

We will be using AngularJS as a comprehensive JavaScript framework that extend the browser capabilities. It handles the heavy lifting of DOM manipulation and AJAX request in a whole.

  2. <html lang="en" ng-app="myModule">
  3. <head>
  4. <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
  5. <link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
  6. </head>
  7. <body ng-controller="myController">
  8. <nav class="navbar navbar-default">
  9. <div class="containet-fluid">
  10. <a class="navbar-brand" href="<a href="https://www.sourcecodester.com">Sourcecodester</a>

  13. </nav>
  14. <div class="col-md-3"></div>
  15. <div class="col-md-6 well">
  16. <h3 class="text-primary">JavaScript - Remove Array Element Using AngularJS</h3>
  17. <hr style="border-top:1px dotted #ccc;"/>
  18. <table class="table table-bordered">

  30. <td>{{member.name}}</td>
  31. <td>{{member.address}}</td>
  32. <td>{{member.gender}}</td>
  33. <td><button type="button" data-toggle="modal" data-target="#delete_member" ng-click = "selectMember(member)" class="btn btn-sm btn-danger"><span class="glyphicon glyphicon-trash"></span> Delete</button></td>
  34. </tr>
  35. </tbody>
  36. </table>
  37. </div>
  38.  
  39. <div class="modal fade" id="delete_member" aria-hidden="true">
  40. <div class="modal-dialog">
  41. <div class="modal-content">

  48. <button class="btn btn-success" data-dismiss="modal"><span class="glyphicon glyphicon-remove"></span> No</button>
  49. </div>
  50. </form>

  53. </div>
  54. </body>
  55. <script src="js/angular.js"></script>

  57. <script src="js/jquery-3.2.1.min.js"></script>
