$("#searchOption").click(function(){ var keys=$("#keys").val(); $.ajax({ type: "POST", url: "action.php", data: "title="+keys, success: function(msg){ if(msg==1){ $("#msg_ser").show().html("没有记录！"); }else{ $("#liOptionms2side__sx").html(msg); $("#msg_ser").html(""); } } }); $("#msg_ser").ajaxSend(function(event, request, settings){ $(this).html(""); }); });

$conn=mysql_connect("localhost","root",""); mysql_select_db("demo",$conn); mysql_query("SET names UTF8");
