這篇文章主要為大家詳細介紹了jquery ztree實現(xiàn)模糊搜索功能，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文分享了jquery ztree實現(xiàn)模糊搜索功能兩個實例，供大家參考，具體內(nèi)容如下

ztree官方demo代碼里的:
根據(jù)參數(shù)查找節(jié)點

這樣就簡單的實現(xiàn)了模糊搜索顯示的功能了。

第二個Ztree樹結(jié)構(gòu)模糊搜索實現(xiàn)方法，具體內(nèi)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') {
    //根節(jié)點：展開     treeObj.expandNode(nodes[i], true, true, false);
   } else {
    //非根節(jié)點：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>.搜索條件   var searchCondition = $('#' + searchConditionId).val();
  //<2>.得到模糊匹配搜索條件的節(jié)點數(shù)組集合   var highlightNodes = new Array();
  if (searchCondition != "") {
   var treeObj = $.fn.zTree.getZTreeObj(treeId);
   highlightNodes = treeObj.getNodesByParamFuzzy("name", searchCondition, null);
  }
  //<3>.高亮顯示并展示【指定節(jié)點s】   highlightAndExpand_ztree(treeId, highlightNodes, flag);
 }
  
 
 function highlightAndExpand_ztree(treeId, highlightNodes, flag){
  var treeObj = $.fn.zTree.getZTreeObj(treeId);
  //<1>. 先把全部節(jié)點更新為普通樣式   var treeNodes = treeObj.transformToArray(treeObj.getNodes());
  for (var i = 0; i < treeNodes.length; i++) {
   treeNodes[i].highlight = false;
   treeObj.updateNode(treeNodes[i]);
  }
  //<2>.收起樹, 只展開根節(jié)點下的一級節(jié)點   close_ztree(treeId);
  //<3>.把指定節(jié)點的樣式更新為高亮顯示，并展開   if (highlightNodes != null) {
   for (var i = 0; i < highlightNodes.length; i++) {

      treeObj.updateNode(highlightNodes[i]);
      //高亮顯示節(jié)點的父節(jié)點的父節(jié)點....直到根節(jié)點，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 {
     //高亮顯示節(jié)點，并展開      highlightNodes[i].highlight = true;
     treeObj.updateNode(highlightNodes[i]);
     //高亮顯示節(jié)點的父節(jié)點的父節(jié)點....直到根節(jié)點，并展示      var parentNode = highlightNodes[i].getParentNode();
     var parentNodes = getParentNodes_ztree(treeId, parentNode);
     treeObj.expandNode(parentNodes, 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) {
   //根節(jié)點    return {color:"#333", "font-weight":"bold"};
  } else if (treeNode.isParent == false){
   //葉子節(jié)點    return (!!treeNode.highlight) ? {color:"#ff0000", "font-weight":"bold"} : {color:"#660099", "font-weight":"normal"};
  } else {
   //父節(jié)點    return (!!treeNode.highlight) ? {color:"#ff0000", "font-weight":"bold"} : {color:"#333", "font-weight":"normal"};
  }
