readyState never gets to 4 on IE
I use this same basic layout for AJAX stuff and for some reason, I can't get it to work this time on IE (works fine in Opera and Firefox).
function getLessonPage(direction)
{
var http = false;
if(navigator.appName == "Microsoft Internet Explorer")
http = new ActiveXObject("Microsoft.XMLHTTP");
else
http = new XMLHttpRequest();
http.abort();
http.open("GET", "/courseware/ajax-lesson.php?direction=" + direction, true);
http.onreadystatechange=function()
{
if(http.readyState == 4)
{
lesson = http.responseText;
document.getElementById("lesson").innerHTML = lesson
}
alert(http.readyState);
}
http.send(null);
}When I run this code in IE, I get alerts for 1, 2, 3 and then it stops. Not sure what's going on. This is the only JavaScript on the page.

Nevermind. I just read that if I change the variable name (in this case, "lesson") it solves the problem. I changed these two lines:
lesson2 = http.responseText;
document.getElementById("lesson").innerHTML = lesson2;
I wonder why calling it something else makes it work in IE...

"lesson" was probably a reserved keyword.

I got the impression that it was because the variable name was the same as the element id. 'lesson' might well be reserved though, which was it Matt?
