    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);
   }

回复讨论(解决方案)

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

我那个哪里出现问题了？

else if( widow.XMLHttpRequest){
xmlHttp=new XMLHttpRequest();
}
window

谢谢~~~~~~~~~~~
