Fancytree不垮已擴展密鑰設定爲節點假

我有以下的JSON樹結構：Fancytree不垮已擴展密鑰設定爲節點假

[ 
    { 
     "expanded":"false", 
     "key":"_23", 
     "title":"Politics", 
     "data":{ 
      "id":"23", 
      "name_en":"Politics",

      } 
     ] 
    }, 
    { 
     "expanded":"false", 
     "key":"_21", 
     "title":"Sport", 
     "data":{ 
      "id":"21",

     }, 
     "children":[ 
      { 
       "key":"_22", 
       "title":"Football", 
       "data":{ 
        "id":"22", 
        "name_en":"Football", 
        "description_en":"", 
        "seo_title_en":"", 
        "seo_description_en":"", 
        "name_sr":"Fudbla", 
        "description_sr":"", 
        "seo_title_sr":"", 
        "seo_description_sr":"", 
        "slug_en":"football", 
        "slug_sr":"fudbla" 
       } 
      } 
     ] 
    } 
]

正如你看到的，在第一級的兩個節點已擴大設置爲false。但那些沒有顯示在樹上倒塌。

我從AJAX請求加載樹。這裏是init代碼：

$("#news-categories-table").fancytree({ 
    icon: false, 
    checkbox: false, 
    titlesTabbable: true, 
    source: { 
     url: SITE_URL + "news_categories/get_tree", 
     cache: false 
    }, 
    extensions: ["table", "dnd"], 
    table: { 
     nodeColumnIdx: 1 // render node expander, icon, and title to this column (default: #0) 
    }, 
    dnd: { 
     autoExpandMS: 400, 
     draggable: { // modify default jQuery draggable options 
      zIndex: 1000, 
      scroll: false, 
      containment: "parent", 
      revert: "invalid" 
     }, 
     preventRecursiveMoves: true, // Prevent dropping nodes on own descendants 
     preventVoidMoves: true, // Prevent dropping nodes 'before self', etc. 
     dragStart: function(node, data) { 
      return true; 
     }, 
     dragEnter: function(node, data) { 
      return true; 
     }, 
     dragExpand: function(node, data) { 
      return true; 
     }, 
     dragOver: function(node, data) { 
      return true; 
     }, 
     dragLeave: function(node, data) { 
      return true; 
     }, 
     dragStop: function(node, data) { 
      return true; 
     }, 
     dragDrop: function(node, data) { 
      data.otherNode.moveTo(node, data.hitMode); 
     } 
    }, 
    renderColumns: function(event, data) { 
     var node = data.node, 
      $tdList = $(node.tr).find(">td"); 

     // td 1 value is edit icon 
     $tdList.eq(0).html(node.data.id); 
    } 
});

可以這樣解決嗎？我之前使用過fancytree，舊版本沒有問題。展開的虛假節點在加載樹時摺疊。

擴展選項需要一個布爾值。嘗試通過的

"expanded": false,

代替

"expanded": "false",

也就是說結構是從fancytree API的這種方法（一個或多個）儲存。喜歡這個。 var tree = $（「＃news-categories-table」）。fancytree（「getTree」）。toDict（false）'。那是錯的嗎？ – cvetan

我發現錯誤。我沒有JSON stringify樹結構將其作爲JSON字符串發送到服務器，但數組。所以當我在服務器上進行JSON編碼時，它會搞亂文件類型。無論如何，現在沒問題。謝謝。 :) – cvetan
