var   treeObj;function  makeStationTree(node_type){    //树的销毁    treeObj = $.fn.zTree.getZTreeObj("tree_station");    treeObj.destroy();    //隐藏所有树节点    treeObj = null;    $.fn.zTree.init($("#tree_station"), setting_station, ztreeNodes);    treeObj = $.fn.zTree.getZTreeObj("tree_station");    var   allNode = treeObj.transformToArray(treeObj.getNodes());    for(var i = 0;i < allNode.length;i++){        allNode[i].nocheck = true;        treeObj.updateNode(node);    }    treeObj.hideNodes(allNode);    //显示当前类型及父亲节点    var  nodelist = treeObj.getNodesByParamFuzzy("node_type",node_type,null);    for(var n = 0;n<nodelist.length;n++){                toshownodeslist[[Number(nodelist[n].id)]]  =  nodelist[n];        checknodes.push(nodelist[n]);        findParent(treeObj,nodelist[n]);    }    $.each(toshownodeslist,function (key,val) {        toshownodesArray.push(toshownodeslist[key]);    })    treeObj.showNodes(toshownodesArray);    //toshownodeslist = [];    toshownodeslist = new Object();    toshownodesArray = [];    checknodeids =[];    //显示的节点再过滤哪些有checkbox    var   treeObj = $.fn.zTree.getZTreeObj("tree_station");    for(var  i=0;i<checknodes.length;i++){        var  node = checknodes[i];        node.nocheck = false;        treeObj.updateNode(node);        checknodeids[i] = node.id;    }    checknodes = [];}function  findParent(treeObj,node){    //treeObj.expandNode(node,true,false,false);    var  pNode =node.getParentNode();    if(pNode!=null){        //toshownodeslist.push(pNode);        toshownodeslist[[Number(pNode.id)]]  =  pNode;        findParent(treeObj,pNode);    }}

涉及到几个点：

ztree隐藏函数hide()

ztree节点nocheck属性

ztree查找父亲节点，避免出现同一父亲几点多次放入数组，使用
var   toshownodeslist = new  Object();
toshownodeslist[[Number(pNode.id)]]  =  pNode;
可以保证唯一性，同一id多次赋值，后面覆盖前面的
涉及Object转正数组[]

 $.each(toshownodeslist,function (key,val) {        toshownodesArray.push(toshownodeslist[key]);    })
