创建reply_updater.php文件，内容如下：
<span style="color: graytext;">是吗？</span>

创建updater.php文件，内容如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="../prototype_1_6.js"></script>
<title>prototype 的Updater</title>

</head>
<body>
<script type="text/javascript">

</script>
<br />
<div id="div1"></div>
</body>
</html>

当我们访问update.php时div1标签对象将显示reply_update.php的内容。

===============加入参数=============

updater.php文件：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="../prototype_1_6.js"></script>
<title>prototype 的Updater</title>

</head>
<body>
<script type="text/javascript">

</script>
<br />
<div id="div1"></div>
</body>
</html>

reply_updater.php文件：
<?php
    if($_GET['param']==1){
        echo "<span style=\"color: graytext;\">是吗？</span>";
    }elseif ($_GET['param']==2){
        echo "<span style=\"color: green;\">是的啊！</span>";
    }
?>

===============加入返回处理选项=============
updater.php文件：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="../prototype_1_6.js"></script>
<title>prototype 的Updater</title>

</head>
<body>
<script type="text/javascript">

</script>
<br />
<div id="div1"></div>
</body>
</html>

reply_updater.php文件：
<?php
    if($_GET['param']==1){
        echo "<span style=\"color: graytext;\">是吗？</span>";
    }elseif ($_GET['param']==2){
        echo "<span style=\"color: green;\">是的啊！</span>";
    }
?>

在上头是使用onFailure:reportError 的javascript进行处理的，而接下来下面是用failure:'error'的div进行显示错误提示。

===================================
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="../prototype_1_6.js"></script>
<title>prototype 的Updater</title>

</head>
<body>
<script type="text/javascript">

</script>
<br />
<div id="div1"></div>
<div id="error"></div>
</body>
</html>

访问updater.php后出现以下结果：

============插入javascript代码==================
reply_updater.php的内容为：
<?php
    if($_GET['param']==1){
        echo <<<EXCERPT
        <script language="javascript" type="text/javascript">
            sayHi= new function(){
                alert('Hi');
            }
        </script>
        <input type=button value="Click Me" >
EXCERPT;
    }elseif ($_GET['param']==2){
        echo <<<EXCERPT
        <script language="javascript" type="text/javascript">
            function sayHi(){
                alert('Hi');
            }
        </script>
        <input type=button value="Click Me" >
EXCERPT;
    }
?>

updater.php内容：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="../prototype_1_6.js"></script>
<title>prototype 的Updater</title>

</head>
<body>
<script type="text/javascript">

</script>
<br />
<div id="div1"></div>
<div id="error"></div>
</body>
</html>
