关于登录的一个函数，我只想问case2是干什么的，为什么要把登录信息以json形式返回
function showMessage($P_message,$P_jumpUrl = '',$P_type = 1,$P_messageType = 'success',$P_time = 2000)
{
if(empty($P_jumpUrl))
{
$P_jumpUrl = getRefUrl();
}
switch ($P_messageType)
{
case 'success':
$L_messageType = '操作成功';
break;
case 'error':
$L_messageType = '操作失败';
break;
case 'warning':
$L_messageType = '操作警告';
break;
}
switch($P_type)
{
case 1:
echo '<!DOCTYPE html>';

json返回的原因，是不是因为要做异步的ajax请求用？
