AJAX call not working in iOS

[bravo14]

Hi

 

I have an AJAX call that populates a select menu based on the selection from a previous menu.  All works on on desktop browser, Safari, Firefox IE etc, however when using iOS the second select menu isn't populating.

 

the AJAX request is as follows

 

 

<script>
function getXMLHTTP() { //fuction to return the xml http object
        var xmlhttp=false;
        try{
            xmlhttp=new XMLHttpRequest();
        }
        catch(e)    {
            try{
                xmlhttp= new ActiveXObject("Microsoft.XMLHTTP");
            }
            catch(e){
                try{
                xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
                }
                catch(e1){
                    xmlhttp=false;
                }
            }
        }

        return xmlhttp;
    }



    function getTeam(strURL) {

        var req = getXMLHTTP();

        if (req) {

            req.onreadystatechange = function() {
                if (req.readyState == 4) {
                    // only if "OK"
                    if (req.status == 200) {
                        document.getElementById('away-team').innerHTML=req.responseText;
                    } else {
                        alert("There was a problem while using XMLHTTP:\n" + req.statusText);
                    }
                }
            }
            req.open("GET", strURL, true);
            req.send(null);
        }

    }
        function getGP(strURL) {

        var req = getXMLHTTP();

        if (req) {

            req.onreadystatechange = function() {
                if (req.readyState == 4) {
                    // only if "OK"
                    if (req.status == 200) {
                        document.getElementById('gp').innerHTML=req.responseText;
                    } else {
                        alert("There was a problem while using XMLHTTP:\n" + req.statusText);
                    }
                }
            }
            req.open("GET", strURL, true);
            req.send(null);
        }

    }
</script>
 
 

 

and the trigger for it...

 

<select name="year" class="txtfield" onChange="getGP('find_gp_ajax.php?season='+this.value)">

 

Any ideas why the call won't work on iOS?

Your code seems OK. The only thing I can think of is that iOS has problems with the try & catch primer function. And why would you wanna use that anyway? IE8+ and all other browsers support XMLHttpRequest(), and coding for IE<8 is a waste of time, if you ask me. IE7 users can easily upgrade to 8, and IE6 has left the building.
