<script type="text/javascript">
var i;
function httprequest(i)
{
 
var xmlhttp;
try
{
 xmlhttp=new XMLHttpRequest();
}

  {
  xmlhttp=new Activexobject("Msxml2.XMLHTTP");
  }
  catch(e)
  { 
    try
    {
    xmlhttp=new Activexobject("MICROSOFT.XMLHTTP")
    }
    catch(e)
    {
     alert("ur browser doesnot support Ajax");
     return false;
    }
  }
 
}
xmlhttp.onreadystatechange=function()
{ 
 if(xmlhttp.readyState==4)
 { 
 
   obj = document.getElementById( "idname" );
 
   obj.innerHTML = xmlhttp.responseText;
   getBufferText();
 
 }
}
 
xmlhttp.open("GET", "second.php?i="+i,true);
xmlhttp.send(null);
}
 
function call_sec(i)

 httprequest(i)
}
</script>
 

<table id="idname">

you have a typo - use:

new ActiveXObject
 

in your IE section for creating the request-object.

Hi

No code is executed on onload of the page.,
The only script on my page is the javascript used for ajax.

I hav enabled script debugging in browser setting., and get tht error which displays in the aert 'document.getElementById('...'') is null or not an object.,

if i disable the script debugging
the page gets loaded well., and displays the result in the status bar as
"done, but with some errors on the page".,

here is my code again

<script type="text/javascript">
var id;
var action;
 
 
function ajaxFunction(id,action)
{
 
var xmlHttp;
try
  {
  // Firefox, Opera 8.0+, Safari
  xmlHttp=new XMLHttpRequest();
  }
catch (e)
  {
  // Internet Explorer
  try
    {
    xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
    }
  catch (e)
    {
    try
      {
      xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
      }
    catch (e)
      {
      alert("Your browser does not support AJAX!");
      return false;
      }
    }
  }
 
xmlHttp.onreadystatechange=function()
{ 
 if(xmlHttp.readyState==4)
 { 
 
   document.getElementById("ajax").innerHTML=xmlHttp.responseText;
 }
}
 
xmlHttp.open("GET","ajax.php?id="+id+"&action="+action,true);
xmlHttp.send(null);
 
}
 
function hidden(id,action)
{
 ajaxFunction(id,action)
}
 
</script>
 

kind regards

the only part i could see where the error could come from is here:

document.getElementById("ajax")

do you have a node with id = 'ajax' in your document? ...
