Angular + jquery ui 可排序

Question

看看这个小提琴https://jsfiddle.net/Lj0swckj/3/

我已经创建了可排序的指令 对于父 div 可排序工作正常 我希望孩子们也能得到同样的东西，并把它作为父母 在给定的示例中，child1、child2、child3 可以交换位置，并且包含 parent1。

我尝试了很多，但找不到任何东西

注意：child1、child2 也可以有子代... （在此示例中，我添加了两个级别的数据，但最多可以是四个级别）

所以我想要一个解决方案，让 sortable 可以适用于这种递归模板。

任何帮助将不胜感激。

angular.module("myApp", []).
controller("myController", ['$scope', function($scope) {
    $scope.fields = [{
    		"name": "parent1",
        "level": 1,
        "children": [{
         		"name": "child1",
            "level": 2
        }, {
        		"name": "child2",
            "level": 2
        }, {
        		"name": "child3",
            "level": 2
        }]
    }, {
    		"name": "parent2",
        "level": 1
    }, {
    		"name": "parent3",
        "level": 1
    }];
    
    $scope.draggableItemsOption = {
    	"moverElement": ".moverBtn",
			"containment": ".draggable-field"
    }
}]).directive("myDragDrop", ['$timeout', function ($timeout) {

		return {
			restrict:'A',
			scope: {
				myDragDrop:"="
			},
			link: function ($scope, element, attrs) {
				var options = $scope.myDragDrop;
				var $container = element;
			
				
				var sortableOptions = {
        	 /* handle: options.moverElement, */
           containment: options.containment,
           delay: 0
				 };


				if($container.sortable){
					$container.sortable(sortableOptions);
				}
				
       }
       }

   border: 1px solid #333;
   padding: 10px 10px;
   position: relative;

嗯！终于有办法了。 其实很简单

看看这个小提琴https://jsfiddle.net/Lj0swckj/6/ 我所做的是创建子元素

angular.module("myApp", []).
controller("myController", ['$scope', function($scope) {
    $scope.fields = [{
    		"name": "parent1",
        "level": 1,
        "children": [{
         		"name": "child1",
            "level": 2
        }, {
        		"name": "child2",
            "level": 2
        }, {
        		"name": "child3",
            "level": 2,
            "children": [{
            		"name": "grandChild1",
                "level": 3
            }, {
            		"name": "grandChild2",
                "level": 3
            }]
        }]
    }, {
    		"name": "parent2",
        "level": 1,
        "children": [{
        	"name": "child4",
          "level":2
        }]
    }, {
    		"name": "parent3",
        "level": 1
    }];
    
    $scope.draggableItemsOption = {
    	"moverElement": ".moverBtn",
			"containment": ".draggable-field"
    }
    
    $scope.childDraggableItemsOption = {
    		"containment": "parent"
    }
}]).directive("myDragDrop", ['$timeout', function ($timeout) {

		return {
			restrict:'A',
			scope: {
				myDragDrop:"="
			},
			link: function ($scope, element, attrs) {

				var options = $scope.myDragDrop;
				var $container = element;
			
				
				var sortableOptions = {
        	 /* handle: options.moverElement, */
           containment: options.containment,
           delay: 0
				 };


				if($container.sortable){
					$container.sortable(sortableOptions);
				}
				
       }
       }
					
	}]);

.element {
   border: 1px solid #333;
   padding: 10px 10px;
   position: relative;
}

.element-class {
  margin-left: 20px;
}

.moverBtn {
  position: absolute;
  top: 2px;
  right: 10px;
}
