@ChaosPandion:

Hey friend don't use this type of check for childNodes.

The counting of childNodes varies. Some browsers include empty textNodes, some do not. In this sort of operation as I believe you are describing, it is better to use the parent's getElementsByTagName() method. That way the number of chidren and index of each child you are looking for will be consistent.

OR

just check your browser's name.

if it is IE then as it neglects empty textnode, the childNode in it is less by one number than other browsers.

for eg.

var isIE = navigator.appName;
if (isIE == "Microsoft Internet Explorer") {                
    var removeProductID = document.getElementById(obj.childNodes[0].id).getAttribute("abc");
}
else {
    var removeProductID = document.getElementById(obj.childNodes[1].id).getAttribute("abc");
}

Hope this helps. Enjoy coding.

Ishwar's answer of changing childNodes to children worked for me.

Answer 3

try getElementsByTagName() instead of ChildNodes. it will be working for FF , chrome and for IE as well.
