jquery – JSTREE – 刷新jstree,以便重新运行’bind(“loaded.jstree”)’中的所有代码

<input type="button" value="Test" onclick='$j("#demo2").jstree("refresh");'/>

现在,当jstree加载时,从2D阵列读取数据,并根据在该阵列中找到的数据更改节点图标.
我需要一个功能,它将刷新或重新加载jstree,同时根据从2D数组读取的数据显示节点的正确图标.

如果我使用’$j(“#demo2”).jstree(“refresh”);’,则重新加载树,但它不会保留其先前的打开状态.

jstree代码

$j("#demo2").jstree({
          "ui" : {
            "SELEct_limit" : -1,"SELEct_multiple_modifier" : "ctrl","SELEct_range_modifier" :"shift",},"json_data" : {
            "progressive_render" : false,"SELEcted_parent_open": true,"ajax" : {
              "url" : "/json/test1.json"
            }
          },"plugins" : [ "themes","json_data","ui","crrm","contextmenu" ],'contextmenu' : {
          'items' : customMenu
          }

      })//end of jstree function


      /***************************************************************************
      When the jstree is first loaded,loop through the data retrieved
      from the database (stored prevIoUsly in a 2d array called 'status_from_db') and
      SELEct all jstree nodes found in that array.
      ***************************************************************************/
     $j("#demo2").bind("loaded.jstree",function (e,data) {    
      var inst = data.inst;
      var i;
      for (i = 0; i < status_from_db.length; ++i) {
          var node_name = status_from_db[i][0];
          $j("#demo2").find($j("lI[name='"+node_name+"']")).each(function (k,v) {
            inst.SELEct_node(v);

      /***************************************************************************
      Based on the retrieved data,assign the correct class to the variable 
      'SELEcted_class and then modify the class of the <li> tag of the respective 
      node.
      ***************************************************************************/
            var node_strength = status_from_db[i][1];
            var node_add_strength = status_from_db[i][2];
            var SELEcted_class;
            if (node_strength == "present" && node_add_strength == ""){
              SELEcted_class = "jstree-icon4";
            }
            else if (node_strength == "present" && node_add_strength == "strong")  {
              SELEcted_class = "jstree-icon3";
            }


            $j("lI[name='"+node_name+"'] > ins").attr("class",SELEcted_class);// set class to display new icon
            $j("lI[name='"+node_name+"'] > a ins").attr("class",SELEcted_class);// set class to display new icon    
          });
      }

   });

});

有没有办法重新加载/刷新树,以便’$j(“#demo2”).bind(“loaded.jstree”,函数(e,data){‘函数)中的所有代码重新运行？
