How to dynamically disable ui-sortable directive in angular-ui

Question

I am using angular-ui for sortable using ui-sortable directive. Is it possible to dynamically enable/disable sortable functionality based on the scope state? So I need to have a button which changes the state of the scope property and depending on this property sortable either should work or not.

Answer 1

The angular directive supports watching when the sortable options change:

scope.$watch(attrs.uiSortable, function(newVal, oldVal){

So all you had to do was look at the jqueryui sortable documentation, and update the correct property on the plugin.

Html

<ul ui-sortable="sortableOptions" ng-model="items">
   <li ng-repeat="item in items">{{ item }}</li>
 </ul>
<button ng-click="sortableOptions.disabled = !sortableOptions.disabled">Is Disabled: {{sortableOptions.disabled}}</button>

JS

app.controller('MainCtrl', function($scope) {
  $scope.items = ["One", "Two", "Three"];

  $scope.sortableOptions = {
    disabled: true
  };
});
