这样就简单的实现了模糊搜索显示的功能了。

第二个Ztree树结构模糊搜索实现方法，具体内容如下

function expand_ztree(treeId){
  var treeObj = $.fn.zTree.getZTreeObj(treeId);
  treeObj.expandAll(true);
 }

 function close_ztree(treeId){
  var treeObj = $.fn.zTree.getZTreeObj(treeId);
  var nodes = treeObj.transformToArray(treeObj.getNodes());
  var nodeLength = nodes.length;
  for (var i = 0; i < nodeLength; i++) {
   if (nodes[i].id == '0') {
    //根节点：展开     treeObj.expandNode(nodes[i], true, true, false);
   } else {
    //非根节点：收起     treeObj.expandNode(nodes[i], false, true, false);
   }
  }
 }

 function search_ztree(treeId, searchConditionId){
  searchByFlag_ztree(treeId, searchConditionId, "");
 }

 function searchByFlag_ztree(treeId, searchConditionId, flag){
  //<1>.搜索条件   var searchCondition = $('#' + searchConditionId).val();
  //<2>.得到模糊匹配搜索条件的节点数组集合   var highlightNodes = new Array();
  if (searchCondition != "") {
   var treeObj = $.fn.zTree.getZTreeObj(treeId);
   highlightNodes = treeObj.getNodesByParamFuzzy("name", searchCondition, null);
  }
  //<3>.高亮显示并展示【指定节点s】   highlightAndExpand_ztree(treeId, highlightNodes, flag);
 }

 function highlightAndExpand_ztree(treeId, highlightNodes, flag){
  var treeObj = $.fn.zTree.getZTreeObj(treeId);
  //<1>. 先把全部节点更新为普通样式   var treeNodes = treeObj.transformToArray(treeObj.getNodes());
  for (var i = 0; i < treeNodes.length; i++) {
   treeNodes[i].highlight = false;
   treeObj.updateNode(treeNodes[i]);
  }
  //<2>.收起树, 只展开根节点下的一级节点   close_ztree(treeId);
  //<3>.把指定节点的样式更新为高亮显示，并展开   if (highlightNodes != null) {
   for (var i = 0; i < highlightNodes.length; i++) {
    if (flag != null && flag != "") {
     if (highlightNodes[i].flag == flag) {
      //高亮显示节点，并展开       highlightNodes[i].highlight = true;
      treeObj.updateNode(highlightNodes[i]);
      //高亮显示节点的父节点的父节点....直到根节点，并展示       var parentNode = highlightNodes[i].getParentNode();
      var parentNodes = getParentNodes_ztree(treeId, parentNode);
      treeObj.expandNode(parentNodes, true, false, true);
      treeObj.expandNode(parentNode, true, false, true);
     }
    } else {
     //高亮显示节点，并展开      highlightNodes[i].highlight = true;
     treeObj.updateNode(highlightNodes[i]);
     //高亮显示节点的父节点的父节点....直到根节点，并展示      var parentNode = highlightNodes[i].getParentNode();
     var parentNodes = getParentNodes_ztree(treeId, parentNode);
     treeObj.expandNode(parentNodes, true, false, true);
     treeObj.expandNode(parentNode, true, false, true);
    }
   }
  }
 }

 function getParentNodes_ztree(treeId, node){
  if (node != null) {
   var treeObj = $.fn.zTree.getZTreeObj(treeId);
   var parentNode = node.getParentNode();
   return getParentNodes_ztree(treeId, parentNode);
  } else {
   return node;
  }
 }

 function setFontCss_ztree(treeId, treeNode) {
  if (treeNode.id == 0) {
   //根节点    return {color:"#333", "font-weight":"bold"};
  } else if (treeNode.isParent == false){
   //叶子节点    return (!!treeNode.highlight) ? {color:"#ff0000", "font-weight":"bold"} : {color:"#660099", "font-weight":"normal"};
  } else {
   //父节点    return (!!treeNode.highlight) ? {color:"#ff0000", "font-weight":"bold"} : {color:"#333", "font-weight":"normal"};
  }
 }

 //==============HTML==============
