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"};
}
}

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。
