<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>
<body>
    <ul>
        <li></li>
        <li></li>
        <li></li>
        <li></li>
        <li></li>
    </ul>
</body>
<script type="text/javascript" src="./jquery.js"></script>
<script type="text/javascript">
    $(\'ul\').click(function(){
        $.get(\'29.php\',function(msg){
            var i=0;
            $.each(msg,function(n,value){
                if (n.length!=1) {
                    var html=\'\';
                    for(var x=0;x<value.length;x++){
                        html+=value[x]+\',\';
                        }
                    html=html.substring(0,html.length-1);
                    $(\'li\').eq(i).html(n+\'后面有\'+html);    
                    

                }else{
                          $(\'li\').eq(i).html(msg[n]+\'后面没有东西\');
                }
                i++;
            });
        },\'json\');
    });
</script>
</html>
