xmlHttpRequest

[cryptinitedemon]

I can't get the response text element in the object to show any actual text.  Basically the html calls jstablerender() when a button is click.  Then XMLhttpRequest calls some file called dummyfile.php which echos out "Hello there sir".  But for some reason it never displays in the alert message.

 

Here's my code

 

var xmlHttp;

function jstablerender()
{ 
xmlHttp=GetXmlHttpObject();
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request")
return
}

var url="dummyfile.php";
xmlHttp.onreadystatechange= function()
{ 
        if (xmlHttp.readyState==4)
        { 
	      alert(xmlHttp.responseText);
        } 
}

xmlHttp.open("GET",url,true);
xmlHttp.send(null);
}


function GetXmlHttpObject()
{
var xmlHttp=null;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
//Internet Explorer
try
  {
  xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
  }
catch (e)
  {
  xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
}
return xmlHttp;
}

 

And then the php file

<?php
echo "Hello there sir";
?>

That code worked for me.  I pretty much copy pasted what you had.  It took about 5 seconds for the alert to pop up, but I think it was due to my webserver lagging itself since I was having similar delays with other code on my site.
