先引入ztree的几个依赖文件:

<link rel="stylesheet" href="lib/zTree/v3/css/zTreeStyle/zTreeStyle.css" type="text/css">
<script type="text/javascript" src="lib/zTree/v3/js/jquery-1.4.4.min.js"></script>
<script type="text/javascript" src="lib/zTree/v3/js/jquery.ztree.core-3.5.js"></script>
<script type="text/javascript" src="lib/zTree/v3/js/jquery.ztree.excheck-3.5.js"></script>

html中写:

<ul id="treeDemo" class="ztree"></ul>

js中配置:

<script type="text/javascript">
	var setting = {
		check: {
                enable: true,
                chkStyle: "radio",
                radioType: "all"
            },
		data: {
			simpleData: {
				enable: true
			}
		},
		callback: {
			onCheck: onCheck //回调选择
        }
	};

	var zNodes =[
		{ id:1, pId:0, name:"鸡鸣寺",nocheck:true}, //表示没有单选框
		{ id:11, pId:1, name:"地点一",nocheck:true},
		{ id:111, pId:11, name:"二食堂"},
		{ id:112, pId:11, name:"三食堂"},
		{ id:12, pId:1, name:"地点二",nocheck:true},
		{ id:121, pId:12, name:"地点2-1"},
		{ id:122, pId:12, name:"地点2-2"}
	];
	function onCheck(e, treeId, treeNode){
		var zTree = $.fn.zTree.getZTreeObj("treeDemo");
		nodes = zTree.getCheckedNodes(true);//获取所选你的id值
         var txt = ""; //获取所有的最底层的叶子节点的id
            for (var i = 0; i < nodes.length; i++) {
                if (nodes[i].isParent) {
            	
                } else {
                    txt += nodes[i].id + ",";
                }
            }
           // txt = txt.replace("null,", ""); //替换选择父节点的id
            txt = txt.substring(0, txt.length - 1);
            //alert(txt);
 
		selVal = nodes[0].id;
		$("#sel").val(selVal);
	}
	$(document).ready(function(){
		$.fn.zTree.init($("#treeDemo"), setting, zNodes);//初始化
		
	});
</script>

最后运行的结果为:

ztree使用-风君雪科技博客

复选框改一个

chkStyle: "checkbox",
