zTree实现基本树


1、实现源码

		var zNodes =[

		];

		$(document).ready(function(){
			$.fn.zTree.init($("#baseTree"), setting, zNodes);
		});
		
		/**
		 * 获取选中节点的编码和名称
		 */
		function findSelect()
		{
		     var treeObj = $.fn.zTree.getZTreeObj("baseTree");
			 var nodes = treeObj.getSelectedNodes();
			 for(var i=0;i<nodes.length;i++)
			 {
			     var nodeId = nodes[i].id;
			     var nodeName = nodes[i].name;
			      alert("树节点编码："+nodeId+"\n"+"树节点名称："+nodeName);
			 }
		}

	</script>
 </head>

<body>
<div class="content_wrap">
	<div class="zTreeDemoBackground left" style="text-align: center;">
		<ul id="baseTree" class="ztree" style="height: 300px; width:200px; overflow-y: auto"></ul>
		<input type="button" id="btn" onclick="findSelect()" value="获取选中节点"/>
	</div>
</div>
</body>
</html>

2、设计结果

（1）初始化



（2）单击按钮



3、设计说明

     获取 zTree 当前被选中的节点数据集合

var treeObj = $.fn.zTree.getZTreeObj("baseTree");
var nodes = treeObj.getSelectedNodes();
