本文实例讲述了jQuery插件zTree实现的多选树效果。分享给大家供大家参考，具体如下：
1、实现代码：
<!DOCTYPE html>
<html>
<head>
<title>多选树</title>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<link rel="stylesheet" type="text/css" href="zTree_v3/csshttps://img.qb5200.com/download-x/demo.css" rel="external nofollow" >
<link rel="stylesheet" type="text/css" href="zTree_v3/css/zTreeStyle/zTreeStyle.css" rel="external nofollow" >
<script type="text/javascript" src="zTree_v3/js/jquery-1.4.4.min.js"></script>
<script type="text/javascript" src="zTree_v3/js/jquery.ztree.core.min.js"></script>
<script type="text/javascript" src="zTree_v3/js/jquery.ztree.excheck.min.js"></script>
<script type="text/javascript">
<!--
var setting = {
check: {
enable: true,
chkStyle: "checkbox",
chkboxType: { "Y": "s", "N": "ps" }
},
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:111, pId:11, name:"汉口"},
{ id:112, pId:11, name:"武昌"},
{ id:12, pId:1, name:"黄石市", open:true},
{ id:121, pId:12, name:"黄石港区"},
{ id:122, pId:12, name:"西塞山区"},
{ id:2, pId:0, name:"湖南省", open:true},
{ id:21, pId:2, name:"长沙市"},
{ id:22, pId:2, name:"株洲市", open:true},
{ id:221, pId:22, name:"天元区"},
{ id:222, pId:22, name:"荷塘区"},
{ id:23, pId:2, name:"湘潭市"}
];
$(document).ready(function(){
$.fn.zTree.init($("#treeMultiple"), setting, zNodes);
});
//-->
</script>
</head>
<body>
<div class="content_wrap" style="text-align: center;">
<div class="zTreeDemoBackground left">
<ul id="treeMultiple" class="ztree" style="height: 300px; width:150px; overflow-y: auto"></ul>
</div>
</div>
</body>
</html>
2、实现效果图：
3、源码说明
（1）Y、N、"p"和“s”说明
Y 属性定义 checkbox 被勾选后的情况；
N 属性定义 checkbox 取消勾选后的情况；
"p" 表示操作会影响父级节点；
"s" 表示操作会影响子级节点。
（2）chkboxType: { "Y": "s", "N": "ps" }
表示checkbox勾选操作，只影响子节点；取消勾选操作，影响父子节点
