[thelist] JavaScript/Ajax - responseText and IE question

[Peter Brunone (EasyListBox.com)]

I had that problem with ELB a while back.

Try request.ResponseText for IE.

And yes, I'm serious.

Not sure if there are many Ajax folks on this list, but maybe someone has an idea to help me with
this issue. I have a very simple Ajax process running that signs a person up to a mailing list and
sends back a confirmation to the page, overwriting the join form. It works perfectly in Mozilla,
but IE is throwing a lovely "unspecified error" (man do I hate that). Using the debugger, I've
found it is complaining about the responseText. 

I'm doing the following onreadystatechange:
========================
function processRequestChange() 
{
m = document.getElementById('msg');
// only if request shows "complete"
if(request.readyState == 2 || request.readyState == 3 )
{
m.innerHTML = "working..."
}
else if (request.readyState == 4) 
{
// only if "OK"
if (request.status == 200) 
{

response = request.responseText;
m = document.getElementById('msg');
m.innerHTML = response;
} 
else 
{
alert("There was a problem retrieving the data:\n" + request.statusText);
}
}
}
=======================

It seems to die on the response and I am not sure why. The php file handling this call is adding
some GET data to a database and then ECHOs a string like so:

=======================
$strResponse = "";

$result = mysql_query("INSERT INTO ctmembers(name, email) VALUES ('$mname', '$mmail')");
if (!$result) {
die('Invalid query: ' . mysql_error());
$strResponse = " 

We're sorry but there is a problem with our mailing list. Please try again
later.";
//TODO: Send myself a notification that there is a failure.
}
else
{
$strResponse = " 

You have successfully been added to the mailing list.";
}

// Close connection
$DB->disconnect();

echo $strResponse; <-- this should be the responseText
====================================

For some reason Mozilla grabs this but IE won't - anyone know why?

Thanks

Tom
