jQuery $.post() function not working in IE unless developer tools is open

Question

The jQuery $.post() function is not working in IE. I tried to open developer tools to see if I was getting a console error, but miraculously the function started working.

It is just a standard $.post() function

$.post('child_cb.php?type=check', { value: $(this).val() }, function(data) {
                        console.log(data);
                        if (data == 'true') {
                            $(".check_case").removeClass('bad').addClass('good');
                        }
                        else if (data == 'false') {
                            $(".check_case").removeClass('good').addClass('bad');
                        }
                    });

I see no reason why it wouldn't work.

are you sure it is not working without developer tools? I wouldn't really trust anything IE. If you want to verify AJAX calls it is best to stick with Fiddler. It will show you what is really going on. — Ilia G, Oct 22 '11 at 20:14
Well, what's the error/symptom(s)? -1 for "it's not working". — , Oct 22 '11 at 20:15
To down voter: really!?!? it is as good a question as any, and asked as well as it can be if you don't know what is going on with the logger. — webLacky3rdClass, Jan 31 '12 at 16:47

remove/comment out the console.log(data), IE cannot process this, it should work fine after you remove this. Had this problem myself recently.

You should make a habit of using this for debugging so you don't forget the console.log :

if(!('console' in window) || ( ('console' in window) && !('log' in console) )){  
    window.console = {  
        log:function(e){  
            alert("You are using console log without the console!")  
        }  
    }  
}

you can remove the alert, but is ok if you want to be notified that you forgot something. :)
