Drag and drop sorting in visualforce page using angularJs


Hello folks,

In this blog I am going to give example to apply drag-drop sorting in visualforce page with use of angularJs.

Lets start with creatting basic Html template to host our app. We will use the ng-app and ng-controller directives to link up the body tag to our Angular application. At the bottom we will include our required libraries.


Prerequisite:

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-sortable/0.15.0/sortable.min.js"></script>


In this code we define an Angular module and name it ngApp, and include the ui.sortable in the requires parameter. This ui.sortable is what wires up angular-ui-sortable to our module. We also define the controller called myController for our module and inject the Angular $scope object. This is where we will set up our Angular sortable.


<script >
      var ngApp = angular.module('myNgApp', ['ui.sortable']);
      ngApp.controller('myController', function ($scope) {

           $scope.names = [ "Test1", "Test2", "Test3" ];

      });


</script>
Now lets use this $scope name variable to display data in Ul by adding ng-model Directive on it and ng-repeat to loop over array.  To make this list sortable, all we need to do is use the ui-sortable directive.
<ul ui-sortable="sortableOptions" ng-model="names">
      <li ng-repeat="person in people" class="list-group-item">{{name}}</li>
</ul>
To see this in action let’s add a pre element and bind it to the people array that will show the order of array in real time.
<pre>{{names}}</pre>

Final code will look like below.
<apex:page standardStylesheets="false" sidebar="false" showHeader="false">
    <apex:slds />
     <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js">
     </script>
     <script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/
jquery-ui.min.js"></script>
     <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.8/
angular.min.js"></script>
     <script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-sortable/
0.15.0/sortable.min.js"></script>
    <script>
          var ngApp = angular.module('ngApp', ['ui.sortable']);
          ngApp.controller('myController', function ($scope) {
    
               $scope.names = [ "Test1", "Test2", "Test3" ];
    
          });
    </script>
    <body ng-app="ngApp" ng-controller="myController">
        <article class="slds-card">
            <div class="slds-card__header slds-grid">
                <div class="slds-media__body">
                    <h2 class="slds-card__header-title">
                      <a href="javascript:void(0);" 
class="slds-card__header-link slds-truncate" title="Names">
                        <span>Name List</span>
                      </a>
                    </h2>
                </div>
                
            </div>
            <div class="slds-card__body slds-card__body_inner">
                <ul ui-sortable="sortableOptions" ng-model="names" 
class="slds-has-dividers_top-space">
                    <li ng-repeat="name in names " class="slds-item">{{name}}</li>
                </ul>
                <pre>{{names}}</pre>
            </div>
        </article>
    </body>
    
</apex:page>
