ajax技术始终出去发送状态
ajax.js代码：
       var xmlHttp;
function S_xmlhttprequest(){
    if(window.ActiveXObject){
       xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    else if(widow.XMLHttpRequest){
       xmlHttp=new XMLHttpRequest();
    }
}
function funphp100(url){
    S_xmlhttprequest();
    xmlHttp.open("GET","for.php?id="+url,true);
    xmlHttp.onreadystatechange=byphp;
    xmlHttp.send(null);
}
function byphp(){
   if(xmlHttp.readyState==1){
   document.getElementById('php100').innerHTML="loading....";
   }
   if(xmlHttp.readyState==4){

          var byphp100 = xmlHttp.responseText;
          document.getElementById('php100').innerHTML=byphp100;

    }

}
for.php代码
          if($id=$_GET[id]){
  for($i=1;$i
echo $i;
sleep(2);
   }
   exit();
}
?>
index.php代码：
          <script></script>
o
t
x

------解决方案--------------------

if($id=$_GET[id]){<br />  for($i=1;$i<=5;$i++){<br /><br />echo $i;<br />//sleep(2);<br />   }<br />   exit();<br />}
