主要應用于添加判斷提示，跳轉，傳回，重新整理。
function alert($tip = "", $type = "", $url = "") {
$js = "
if ($tip)
$js .= "alert(‘" . $tip . "‘);";
switch ($type) {
case "close" : //關閉頁面
$js .= "window.close();";
break;
case "back" : //傳回
$js .= "history.back(-1);";
break;
case "refresh" : //重新整理
$js .= "parent.location.reload();";
break;
case "top" : //架構退出
if ($url)
$js .= "top.location.href=‘" . $url . "‘;";
break;
case "jump" : //跳轉
if ($url)
$js .= "window.location.href=‘" . $url . "‘;";
break;
default :
break;
}
$js .= "";
echo $js;
if ($type) {
exit();
}
}
