php100第48讲出现问题 急求解

index.php

<?php
/*
* Created on 2010-9-7
*
* To change the template for this generated file go to
* Window - Preferences - PHPeclipse - PHP - Code Templates
*/

?>
<script language="JavaScript" type="text/javascript" src="file.js"></script>

<a href="#" onclick="funphp100('o')">o</a>
<a href="for.php?id=o">o</a>
<a href="for.php?id=t">t</a>
<a href="for.php?id=x">x</a>
<div id="php100"></div>




afile.js页面<!--<script language="JavaScript" type="text/javascript">-->
var xmlHttp;
function xmlhttprequest(){
    if(window.ActiveXObject){
        xmlHttp = new ActiveXObject('Microsoft.XMLHTTP');
    }else if(window.XMLHttpRequest){
        xmlHttp = new XMLHttpRequest();
    }
}


function funphp100(url){
    xmlhttprequest();
    xmlHttp.open("GET","for.php?id="+url,true);
    xmlHttp.onreadystatechange=byphp;
    XmlHttp.send(null);
}


function byphp(){
    var byphp100 = xmlHttp.responseText;
    document.getElementById('php100').innerHTML=byphp100;
}
</script>



for页面
<?php
/*
* Created on 2010-9-7
*
* To change the template for this generated file go to
* Window - Preferences - PHPeclipse - PHP - Code Templates
*/
if($id=$_GET[id]){
     for($i=1;$i<10;$i++){
         echo $id;
     }
         exit();

}
?>



点击index.php的o不起作用  一点感觉都没有

afile.js页面   <!--<script language="JavaScript" type="text/javascript">--></script>去掉；
XmlHttp.send(null);  改为“xmlHttp.send(null); ”

谢谢了
