zTree实现单独选中根节点中第一个节点


1、实现源码

	<script type="text/javascript">
		<!--
		var setting = {
			data: {
				simpleData: {
					enable: true
				}
			}
		};

		var zNodes =[
			{ id:1, pId:0, name:"湖北省", open:true},
			{ id:11, pId:1, name:"武汉市", open:true},

			{ id:223, pId:22, name:"芦淞区"},
			{ id:224, pId:22, name:"石峰区"}
		];

		$(document).ready(function(){
			$.fn.zTree.init($("#baseTree"), setting, zNodes);
		});
		
		/**
		 *  单独选中根节点中第一个节点
		 */
		function selectNodes()
		{
		    var treeObj = $.fn.zTree.getZTreeObj("baseTree");
		    //获取节点
		    var nodes = treeObj.getNodes();
			if (nodes.length>0) 
			{
		        var node = treeObj.selectNode(nodes[0]);
		        alert(node);
			}
		}
		//-->
	</script>
 </head>

<body>
<div class="content_wrap">
	<div class="zTreeDemoBackground left">
		<ul id="baseTree" class="ztree" style="height: 300px; width:200px; overflow-y: auto"></ul>
		<input type="button" id="btn" onclick="selectNodes()" value="单独选中根节点中第一个节点"/>
	</div>
</div>
</body>
</html>
