参考例子如下：
<script type="text/javascript" src="http://www.coding123.net/rardownload/20110420/20110420113851756.js"></script><!--倒入json.js文件，序列化json对象用的-->
<script type="text/javascript" src="http://www.coding123.net/js/jquery.js"></script>
<script type="text/javascript">
var zNodes =[
{ id:1, pId:0, name:"随意勾选 1", open:true},
{ id:11, pId:1, name:"随意勾选 1-1", open:true},
{ id:111, pId:11, name:"随意勾选 1-1-1"},
{ id:112, pId:11, name:"随意勾选 1-1-2"},
{ id:12, pId:1, name:"随意勾选 1-2", open:true},
{ id:121, pId:12, name:"随意勾选 1-2-1"},
{ id:122, pId:12, name:"随意勾选 1-2-2"},
{ id:2, pId:0, name:"随意勾选 2", checked:true, open:true},
{ id:21, pId:2, name:"随意勾选 2-1"},
{ id:22, pId:2, name:"随意勾选 2-2", open:true},
{ id:221, pId:22, name:"随意勾选 2-2-1", checked:true},
{ id:222, pId:22, name:"随意勾选 2-2-2"},
{ id:23, pId:2, name:"随意勾选 2-3"}
]
$.ajax({
url:'xxxx.php'//改为你的动态页
,type:'POST'
,data:{zNodes:zNodes.toJSONString()}//调用json.js类库将json对象转换为对应的JSON结构字符串
,success:function(rst){alert('PHP接收JSON数据成功！')}
,error:function(xhr){alert('PHP页面有错误！'+xhr.responseText)}
}})
</script>
$zNodes=$_POST["zNodes"]
$json=json_decode($zNodes)//转化为JSON对象
php中的数组转换成json格式,然后输出到页面中.<script type='text/javascript'>
var arr = <?php echo $json?>
</script>
var addbgm =new Array()<?phpforeach($dellieb as $value){
echo "addbgm[addbgm.length]=".$value
}
?>
