Once u have debugger installed and *enabled*, IE should automatically
break when a js error is encountered. Typically IE will ask you if u
wanna debug this error or not. Clicking "debug" will open the script
editor and stop execution on the line of code where the error was
encountered. This is one of the ways to getting into the debugger at
runtime.
Another way is to add the command "debugger" anywhere in your js code.
Debugger will break on that statement automatically as well.
There are many more options that u can set to get into debug mode...
Eitherways, once you are inside the debugger, there are quite a few
things u can do...
1. you can see a window titled "immediate window". This is one of the
most useful windows there. Here, whatever js command u type in is
executed and the result displayed right there. This enables you to
check the behavior of various methods, values of objects, elements etc.
2. There should be a call stack window somewhere, which will help u
see the flow of method calls that lead u to where u are... this can be
very useful to debug pretty annoying errors.
3. then, coming to the primary functionality of a debugger. You can
step into, step out, step through code, one line at a time. This way u
can see what is stored in each variable during execution of each line.
4. There is a watch feature, in which u can type in some expression
and always keep an eye on what the expression returns while stepping
through the debugger. this is different from immediate
window in that, the expression is evaluated only once in the immediate window, whereas the watch keeps track of the current value of the expression always.
5. There is a local variable window somewhere, where u can see the
values of all the local variables.
There is more you can do with it
A very basic tutorial can be found here as well.

Okay, so after looking for a while online it seems that most
people think that Microsoft Script Editor is superior in debugging
to Visual Studio or Microsoft Script Debugger. So, I've got MSE
installed, and now I'm having trouble using it. I'll admit to
never having used a debugger before. I've always just used alerts,
and dumps and such in my code to stop the program flow or to tell
me the value of some variable.
The stuff I've read online so far just seem to be talking about
how to enable debugging in IE and then how to start the debugger.
They don't really cover what to do when once the debugger opens.
Can anyone help me with using this thing? Or can someone point me
to a good resource on learning to use this debugger?
Thanks heaps!

yes, u r right, u have to have one of those applications... i
have used both script debugger and script editor. both are ok...
so, first download and install it... and then follow the
instructions that is given on the top of the blog entry. This
should result in ur view->script debuggger menu...
if it doesnt, then goto options, disable script debbugging, the
close IE, then open IE again, then enable script debugging again,
then close IE and then open IE again. it should work...

Thanks heaps, Mike! I've a question though.
That blog entry you point to says:
"When you've enabled Script Debugging 'View->Script Debugger'
will now
be present to help you break into the debugger."
But, I'm not finding that's the case. Also, it goes on to
talk about
three applications that the author has used for script
debugging. Do I
have to have one of those in order to debug? Why don't I have
the
'View->Script Debugger'? Have you used this debugger in IE?
How many
angels can dance on the head of a pin? What are the eleven secret
herbs and spices in Kentucky Fried Chicken? Can God make a
rock so
heavy even He can't lift it? Are you tired of my questions
yet? ;o)
Any help would be appreciated.
Thanks again,
Chris
