Issues have been encountered with the functionality of the script (AJAX or JS) in IE8

I'm currently troubleshooting a js/ajax script hosted at

A recent complaint notified me that it's not functioning properly on IE8.

The onchange event seems to be working, however the subsequent menu isn't being populated.

Can anyone assist me in resolving this issue?

Your help is greatly appreciated!

I'm unsure of which part of the code is causing the problem, but my hunch is:

if (window.XMLHttpRequest) {//  code for IE7+, Firefox, Chrome, Opera, Safari
                xmlhttp=new XMLHttpRequest();
            } else {//                      code for IE6, IE5
                xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
            }
            newList="";
            xmlhttp.onreadystatechange=function() {
                if (xmlhttp.readyState==4 && xmlhttp.status==200) {
                    newList = xmlhttp.responseText;
                    m1.innerHTML=newList;
                    m1.disabled=false;
                }
                if (menuname=="showCountry")  {
                    var c1=document.getElementById('showRegion');
                    if (c1.options.length==2) {
                        if (c1.options[0].value=='NONE') {
                            c1.remove(0);
                            c1.value='0';
                            reloadmenu(c1);
                        }
                    }
                }
            }
            xmlhttp.open("GET",newFile+".php?q="+menuvalue,true);
            xmlhttp.send();

Answer №1

The problem lies in the line of code below:

m1.innerHTML=newList;

This issue arises because you are using innerHTML to append <option> elements to a <select>. Unfortunately, this is a known bug in Internet Explorer 8 - you can find more information about it here: http://support.microsoft.com/kb/276228.

Tip: To test your page in Internet Explorer, you can open Developer Tools and switch to IE8 mode (check out this guide for more details: )
