php异步jquery

这是json.html












function _GetData()
{
var sid=$("#sid").val(); //jQ获取用户输入的值
$.ajax(
{
type:"POST",
url:"json.php",
data:{"stu_id":sid},
cache:false,
dataType:"json",
success:function(msn)
{
var content="";
$.each(msn,function(i)
{content+="";
} );
content+="
id 姓名 专业 电话 学号
"+msn[i][0]+" "+msn[i][1]+" "+msn[i][2]+" "+msn[i][3]+" "+msn[i][4]+"
";
$("#test").html(content);
}
});
}


这是json.php
$sid=$_POST["sid"];
include 'comm.php'; //连接数据库
$sql = "select * from stu where stu_id={$sid}";
$result = mysql_query($sql);
while ($row = mysql_fetch_array($result)) {
$arr[] = $row;
}
echo json_encode($arr);
<code>    输入的数据不能通过ajax传到php页面处理!</code>
