本文分享了jquery ztree实现模糊搜索功能两个实例，供大家参考，具体内容如下
ztree官方demo代码里的:
根据参数查找节点
以上文件修改成如下代码

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) "#ff0000", "font-weight":"bold"} : {color:"#660099", "font-weight":"normal"}; } else { //父节点 return (!!treeNode.highlight) "#ff0000", "font-weight":"bold"} : {color:"#333", "font-weight":"normal"}; } } //==============HTML============== class="padd" style="padding-bottom: 0px;"> class="input-append row-fluid" style="margin-bottom: 0px;"> "search_condition" type="text" placeholder="请输入搜索条件" class="span8" style="font-size:12px"/> "button" class="btn btn-info" onclick="search_ztree('dep_tree', 'search_condition')">搜索 "dep_tree" class="ztree">更多关于ztree控件的内容，请参考专题《jQuery插件ztree使用汇总》 。
以上就是jquery ztree实现模糊搜索功能的代码，希望对大家的学习有所帮助。
