是否可以通过拖放移动/排序/重新排序 Angular UI 选项卡？

Question

以前版本的 Angular UI 似乎可行（请参阅 here），但我尝试使用 uib-tabset，但它不起作用。有什么想法吗？

这不起作用：

 <uib-tabset sortable-tab>
    <uib-tab heading="Title 1">
      Some text 1
    </uib-tab>
    <uib-tab heading="Title 2">
      Some text 2
    </uib-tab>
 </uib-tabset>

PLUNK

Answer 1

它仍然有效。您必须应用该指令。您的示例中的指令尚未内置到 ui 中。这是一个Plunker，它适用于新版本。

在您的 HTML 中：

    <uib-tabset>
 <uib-tab sortable-tab ng-repeat="tab in data.tabs" heading="{{tab.title}}" active="tab.active" disabled="tab.disabled">
        <p>{{tab.content}}</p>
      </uib-tab>
      <uib-tab disabled="true">
        <uib-tab-heading>
          <i class="glyphicon glyphicon-plus"></i>
        </uib-tab-heading>
      </uib-tab>
         </uib-tabset>

您还必须在控制器中包含该指令：

   app.directive('sortableTab', function($timeout, $document) {
  return {
    link: function(scope, element, attrs, controller) {
      // Attempt to integrate with ngRepeat
      // https://github.com/angular/angular.js/blob/master/src/ng/directive/ngRepeat.js#L211
      var match = attrs.ngRepeat.match(/^\s*([\s\S]+?)\s+in\s+([\s\S]+?)(?:\s+track\s+by\s+([\s\S]+?))?\s*$/);
      var tabs;
      scope.$watch(match[2], function(newTabs) {
        tabs = newTabs;
      });

      var index = scope.$index;
      scope.$watch('$index', function(newIndex) {
        index = newIndex;
      });

      attrs.$set('draggable', true);

      // Wrapped in $apply so Angular reacts to changes
      var wrappedListeners = {
        // On item being dragged
        dragstart: function(e) {
          e.dataTransfer.effectAllowed = 'move';
          e.dataTransfer.dropEffect = 'move';
          e.dataTransfer.setData('application/json', index);
          element.addClass('dragging');
        },
        dragend: function(e) {
          //e.stopPropagation();
          element.removeClass('dragging');
        },

        // On item being dragged over / dropped onto
        dragenter: function(e) {
        },
        dragleave: function(e) {
          element.removeClass('hover');
        },
        drop: function(e) {
          e.preventDefault();
          e.stopPropagation();
          var sourceIndex = e.dataTransfer.getData('application/json');
          move(sourceIndex, index);
          element.removeClass('hover');
        }
      };

      // For performance purposes, do not
      // call $apply for these
      var unwrappedListeners = {
        dragover: function(e) {
          e.preventDefault();
          element.addClass('hover');
        },
        /* Use .hover instead of :hover. :hover doesn't play well with 
           moving DOM from under mouse when hovered */
        mouseenter: function() {
          element.addClass('hover');
        },
        mouseleave: function() {
          element.removeClass('hover');
        }
      };

      angular.forEach(wrappedListeners, function(listener, event) {
        element.on(event, wrap(listener));
      });

      angular.forEach(unwrappedListeners, function(listener, event) {
        element.on(event, listener);
      });

      function wrap(fn) {
        return function(e) {
          scope.$apply(function() {
            fn(e);
          });
        };
      }

      function move(fromIndex, toIndex) {
        // http://stackoverflow.com/a/7180095/1319998
        tabs.splice(toIndex, 0, tabs.splice(fromIndex, 1)[0]);
      };

    }


     }

    });

该指令还使用ng-repeat 作为动态标签：

      $scope.data = [];
  $scope.data.tabs = [
    { title:'Dynamic Title 1', content:'Dynamic content 1', active:true},
    { title:'Dynamic Title 2', content:'Dynamic content 2'},
    { title:'Dynamic Title 3', content:'Dynamic content 3'}
  ];
