一、节点模糊搜索功能：搜索成功后，自动高亮显示并定位、展开搜索到的节点。
二、节点异步加载：1、点击展开时加载数据；2、选中节点时加载数据。
前台代码如下：
js：
<script type="text/javascript">
//ztree设置
var setting = {
view: {
fontCss: getFontCss
},
check: {
enable: true
},
data: {
simpleData: {
enable: true,
idKey: "id",
pIdKey: "pId",
rootPId: 0
}
},
async: {
enable: true,
url: "#{getStudentsJsonUrl}",
autoParam: ["id", "level"]},
callback: {
beforeCheck: zTreeBeforeCheck,
onNodeCreated: zTreeOnNodeCreated,
beforeExpand: zTreeBeforeExpand
}
};var reloadFlag = false; //是否重新异步请求
var checkFlag = true; //是否选中
//节点展开前
function zTreeBeforeExpand(treeId, treeNode) {
reloadFlag = false;
return true;
};
//节点创建后
function zTreeOnNodeCreated(event, treeId, treeNode) {
var zTree = $.fn.zTree.getZTreeObj(treeId);
if (reloadFlag) {
if (checkFlag) {
zTree.checkNode(treeNode, true, true);
}
if (!treeNode.children) {
zTree.reAsyncChildNodes(treeNode, "refresh");
}
}
};
//选中节点前
function zTreeBeforeCheck(treeId, treeNode) {
var zTree = $.fn.zTree.getZTreeObj(treeId);
if (!treeNode.children) {
reloadFlag = true;
checkFlag = true;
zTree.reAsyncChildNodes(treeNode, "refresh");
}
return true;
}
//页面加载完成
_run(function () {
require(['zTree/js/jquery.ztree.all-3.5'], function () {
$.ajax({
type: "POST",
url: "#{getStudentsJsonUrl}",
success: function (data) {
if (data && data.length != 0) { //如果结果不为空
$.fn.zTree.init($("#tree"), setting, data);
}
else { //搜索不到结果
}
}
});
});
//提交
$("#inputSubmit").click(function () {
var zTree = $.fn.zTree.getZTreeObj("tree");
var nodes = zTree.getCheckedNodes(true);
var ids = "";
var names = "";
for (var i = 0; i < nodes.length; i++) { //遍历选择的节点集合
if (!nodes[i].isParent) {
ids += nodes[i].id.replace("level" + nodes[i].level, "") + ",";
names += nodes[i].name + ",";
}
}
Simpo.ui.box.hideBox();
parent.$(".boxFrm").contents().find("#inputRange").val(names.substr(0, names.length - 1));
parent.$(".boxFrm").contents().find("#hidRange").val(ids.substr(0, ids.length - 1));
})
});
//查找节点
var lastNodeList = [];
var lastKey;
function searchNode() {
var zTree = $.fn.zTree.getZTreeObj("tree");
var key = $.trim($("#inputSearchNode").val());
if (key != "" && key != lastKey) {
nodeList = zTree.getNodesByParamFuzzy("name", key);
for (var i = 0, l = lastNodeList.length; i < l; i++) { //上次查询的节点集合取消高亮
