JeeSite4+zTree实现Tree树状图

zTree API文档：

1、使用：‘js_sys_office’表创建树表代码， 2、将模块添加到菜单栏中 3、编写OfficeController，添加一个跳转页面的请求

@RequiresPermissions("sys:office:view")
@RequestMapping(value = "index")
public String index(Office office, Model model) {
	return "modules/sys/officeIndex";
}

4、编写前端页面：officeIndex.html

<% layout(/layouts/default.html, {title: 用户管理, libs: [layout,zTree]}){ %>
<div class="ui-layout-west">
	<div class="main-content">
		<div class="box box-main">
			<div class="box-header">
				<div class="box-title">
					<i class="fa icon-grid"></i> ${text(组织机构)}
				</div>
				<div class="box-tools pull-right">
					<% if(hasPermi(sys:office:edit)){ %>
						<button type="button" class="btn btn-box-tool addTabPage" data-href="${ctx}/sys/office/list" title="${text(机构管理)}"><i class="fa fa-edit"></i></button>
					<% } %>
					<button type="button" class="btn btn-box-tool" id="btnExpand" title="${text(展开)}" style="display:none;"><i class="fa fa-chevron-up"></i></button>
					<button type="button" class="btn btn-box-tool" id="btnCollapse" title="${text(折叠)}"><i class="fa fa-chevron-down"></i></button>
					<button type="button" class="btn btn-box-tool" id="btnRefresh" title="${text(刷新)}"><i class="fa fa-refresh"></i></button>
				</div>
			</div>
			<div class="ui-layout-content">
				<div id="tree" class="ztree"></div>
			</div>
		</div>
	</div>
</div>
<div class="ui-layout-center">
	<iframe id="mainFrame" name="mainFrame" class="ui-layout-content p0"
		src="${ctx}/sys/empUser/list"></iframe>
</div>
<% } %>

<script>
// 初始化布局
$(body).layout({
	west__initClosed: $(window).width() <= 767, // 是否默认关闭
	west__size: 200
});
// 主页框架
var win = $("#mainFrame")[0].contentWindow;


// 树结构初始化加载
var setting = {view:{selectedMulti:false},data:{key:{title:"title"},simpleData:{enable:true}},
	callback:{onClick:function(event, treeId, treeNode){
		tree.expandNode(treeNode);
		//win.$(button[type=reset]).click();
		win.$(#officeCode).val(treeNode.id);
		win.$(#officeName).val(treeNode.name);
		win.page(1);
	}}
}, tree, loadTree = function(){
	js.ajaxSubmit("${ctx}/sys/office/treeData?___t=" + new Date().getTime(),
			{ctrlPermi:${@Global.getConfig("user.adminCtrlPermi", "2")}/*1拥有的权限 2管理的权限*/}, function(data){
		tree = $.fn.zTree.init($("#tree"), setting, data);//.expandAll(true);
		// 展开第一级节点
		var nodes = tree.getNodesByParam("level", 0);
		for(var i=0; i<nodes.length; i++) {
			tree.expandNode(nodes[i], true, false, false);
		}
		// 展开第二级节点
// 		nodes = tree.getNodesByParam("level", 1);
// 		for(var i=0; i<nodes.length; i++) {
// 			tree.expandNode(nodes[i], true, false, false);
// 		}
	}, null, null, js.text(loading.message));
};loadTree();


// 工具栏按钮绑定
$(#btnExpand).click(function(){
	tree.expandAll(true);
	$(this).hide();
	$(#btnCollapse).show();
});
$(#btnCollapse).click(function(){
	tree.expandAll(false);
	$(this).hide();
	$(#btnExpand).show();
});
$(#btnRefresh).click(function(){
	loadTree();
});
// 调用子页分页函数
function page(){
	win.page();
}
</script>
