<script src="jquery-1.11.2.min.js"></script>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

</head>

<body>
    <div style="width:200px; height:35px; border:2px solid #60f">
        <input style="width:196px; height:31px;" type="text" id="name" />

                if(n!="")
                {
                    $.ajax({
                            url:"listchuli.php",
                            data:{n:n},
                            type:"POST",
                            dataType:"TEXT",
                            success: function(data){
                                    var sz=data.split("|");
                                    var str="";
                                    for(var i=0;i<sz.length;i++){
                                            str=str+"<div class='1'>"+sz[i]+"</div>";

                                        $("#list").html(str);
                                }
                                
                        });
                    }
                    else{
                            $("#list").html("");
                        }
            });
    </script>
</body>
</html>

2.处理页面

<?php
$name = $_POST["n"];

include("./lei/AAA.class.php");
$db = new AAA();

$sql = "select name from info where name like '%{$name}%' ";

echo $db->StrQuery($sql);
