php中javascript怎么处理？

[loswing]

我写了一个函数
function ms_confirm($ms,$url)
{
echo"<script language=javascript>";
echo" var truthBeTold = window.confirm(\"$ms\");";
echo" if (truthBeTold) { ";
echo"";
echo" } else {";
if($url==null)
{
echo"history.go(-1);";
echo"}";
echo"</script>";
echo "url=null";
exit;
}
else
{
echo"self.location.href='$url';";
echo"}";
echo"</script>";
echo"url";
exit;
}
}
希望能够
<?
ms_confirm("删除？","url");
echo "gogogo";
?>
确定时继续执行echo "gogogo";
取消时回到url
可是当点确定时显示:url=null

开玩笑吧？
请您先把b/s的运行机制搞搞清楚

晕！那windows.confirm()得到的判断
