Angularjs基于json数据的可排序项和类别

Question

我有这个json结构:

{  
   "items":[  
      {  
         "category":"Category 1",
         "name":"01",
         "id":"46701a72410c"
      },
      {  
         "category":"Category 2",
         "name":"02",
         "id":"9a18ffe9f148"
      },
      {  
         "category":"Category 2",
         "name":"03",
         "id":"de3a49a458cc"
      },
      {  
         "category":"Category 3",
         "name":"04",
         "id":"bb06b1eec9c8"
      },
      {  
         "category":"Category 3",
         "name":"05",
         "id":"92973f4cfbfc"
      },
      {  
         "category":"Category 3",
         "name":"06",
         "id":"b06bbb86d278"
      }
   ],
   "categories":[  
      {  
         "isCollapsed":false,
         "name":"Category 1"
      },
      {  
         "isCollapsed":false,
         "name":"Category 2"
      },
      {  
         "isCollapsed":false,
         "name":"Category 3"
      }
   ]
}

我正在尝试使用angularjs ui.sortable添加排序行为.我希望类别和项目都可以排序.

我基于这个json创建了两个嵌套的有序列表,但我不知道如何解决可排序的设置.这个json结构有可能吗？

通过这些设置,我只解决了类别排序工作.问题是移动项目时(错误的位置或未定义).

$scope.sortableOptionsCategories = {
    stop: function(ev, ui) {
      console.log("Category moved.");
    }
  };

$scope.sortableOptionsItems = {
  connectWith: '.items-container',
  start: function(e, ui) {
    $(this).attr('data-previndex', ui.item.index());
    console.log("Start: from position " + ui.item.index());
  },

  update: function(e, ui) {
    var newIndex = ui.item.index();
    var oldIndex = $(this).attr('data-previndex');
    $(this).removeAttr('data-previndex');
    console.log("Update: " + oldIndex + " -> " + newIndex);
  },

  stop: function(ev, ui) {
    console.log("Item moved.");
  }
};

更新: 这是我的代码:http: //codepen.io/anon/pen/LpGmeY 保持json的解决方案对我来说是完美的,但如果不可能,我会接受任何其他解决方案.

您是否尝试过使用这个库 - https://github.com/angular-ui-tree/angular-ui-tree

我创建了一个 jsfiddle - http://jsfiddle.net/450fk7wp/5/ - 处理嵌套、可排序、可拖动的项目。

您必须转换 JSON，使其看起来像这样：

$scope.rows = [{
  "name":"Category 1",
  "columns": [
    {
     "category":"Category 1",
     "name":"01",
     "id":"46701a72410c"
    }
  ],
}, {
  "name":"Category 2",
  "columns": [
    {  
       "category":"Category 2",
       "name":"02",
       "id":"9a18ffe9f148"
    },
    {  
       "category":"Category 2",
       "name":"03",
       "id":"de3a49a458cc"
    }
  ],
}, {
  "name":"Category 3",
  "columns": [
  {  
     "category":"Category 3",
     "name":"04",
     "id":"bb06b1eec9c8"
  },
  {  
     "category":"Category 3",
     "name":"05",
     "id":"92973f4cfbfc"
  },
  {  
     "category":"Category 3",
     "name":"06",
     "id":"b06bbb86d278"
  }
  ]
}];

只是不确定您正在寻找什么类型的排序功能。

希望这可以帮助！
