'Undefined' Error with PHP and AJAX

Hi

Having problem with a simple AJAX call, I just keep getting an undefined error when I run this. I have checked the PHP file (getClassCodes.php) and that returns
data as it should, and I can see that working in the HTTP monitor in Netbeans, but when it goes to get the reponse - I just get 'undefined'.

Here is the simple PHP page:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title></title>
         <script>
                includeJS("../javascript/core_javascript.js");
                var myRequest;
                function getClassCodes(teacherId){
                    myRequest = getXMLHTTPRequest();
                    var url = 'getClassCodes.php?teacher_Id=' + teacherId;
                    var myRandom = getRandomNumber();
                    myRequest.open('GET',url + '&rand=' + myRandom,true);
                    myRequest.onreadystatechange = responseAjax;
                    myRequest.send(null);
                }
                function responseAjax(){

if(myRequest.readyState==4){
                        document.getElementById('classTable').innerHTML = myRequest.reponseText
                    }
                }
                function test(){
                    alert("Hello");
                }
                function includeJS(jsFile){
                    var js = document.createElement("script");
                    js.setAttribute("type","text/javascript");
                    js.setAttribute("src",jsFile);
                    document.getElementsByTagName("head")[0].appendChild(js);
                }

</script>
    </head>
    <body>
        
        <div id="classTable">
            <b>Data should be here</b>
        </div>
        <form id="f" method="post" action="">
            <input type="button" name="btn1" value="click" onclick="getClassCodes('matt')"/>
        </form>
    </body>
</html

and here is the JS file that I am using:

Please can anyone help.

kind regards

What is undefined? Is there a JavaScript error?

What does the status and statusText say?

Have you used Firebug to figure out what is going on?

Hi

That is the problem - it just says 'undefined' in the response. I will have a look at firebug if you think that it is useful.

kind regards

Status of 200 and a Status Text of OK - not sure what to do with Firebug - still just getting 'undefined' as the responseText.

Then it's likely a problem in your php.

Firebug lets you see the request go out and come back in the console if you enable it.

I have spotted it - it is a typo in responseAjax - I have typed reponseText insteam of responseText.

That is several hours of my life that I won't get back

Never mind - and thanks for the heads up about Firebug, it looks quite useful

LOL, I stared at your code for spelling mistakes and somehow missed that.
