I have an Ajax app which works fine in firefox but dies in IE.

The code below shows what happens after the request returns a result which is a series of comma separated strings:
...
results = http.responseText.split(",");
id=results[0];
stat=results[1];
comment=results[2];
...

IE says "Object does not support property or method" and the debugger points me to the line:
stat=results[1];

but this does not make sense to me... what property or method? Does the debugger aleways point to the right line, or should I be looking elsewhere?

Quite often, the problem is the line above it.

Is HTTP being created correctly as an IE object? Does it have a value for responseText when it comes out?

alert() is your friend in this case. Use it to try and track your output.

That's all great advice ADAM. Yes http is being created OK, and the response is valid. The line above is also a no-brainer which shouldnt throw that message. The error message might make sense if the error was the line with split(), especially if responseText was empty maybe, but I had already checked using alert() and found the same string as firefox sees.


Seems to affect all versions of IE though... FF is happy.

Okay. This is going to sound like a waste of time, and really stupid, but sometimes things like this work.

Try gathering the responseText into one variable, and splitting it using another variable on a separate line. It may be the combination of the two that IE has the problem with.

Sorry dude...I can't think of anything else, unless perhaps you've got a sample page you can show us. Maybe we can deconstruct, reconstruct, and find the answer that way.

well i found it. thanks for your help adam.

The problem was the use of the word 'stat' as a variable!

It must be some kind of reserved word in IE.
