I have a function called myFunction that can be called once from an
onclick() or 100 times from a function called loopFunction which
contains a for(var i=0;i<100;i++) loop.
Within myFunction is a setTimeout() function like this:
setTimeout(func tion(){shuffleD oor()},1500);
Now, when I call myFunction from onclick() it waits 1.5 seconds and
then calls the shuffleDoor function, just as I imagine it should.
However when I call the function from loopFunction it is called 100
times but there is no 1.5 second delay between calls.
Why is this?
Thanks in advance. 6 2268

Because you're doing it wrong. Your error is at line 15.
Whenever you suspect a bug in a javascript/host implementation (or any
other system that people have been using for years), it's your job to
show that the bug is really there. Since you haven't done that, I'm
going to assume the bug is really in your own code. Show the actual
code, and we can probably find the actual problem.

ok

only the first one, I suppose
Why is this?
because the elapse time between single call of the loop is infinitesimal,
setTimeout does not stall the script, the script continues immediately (not
waiting for the timeout to expire); you schedule 100 contemporaneous
actions.
If you want execute the same function every 1,5 sec, the better way is to
use setInterval

Thank you Ugo for a very clear and useful answer.

This kind of smartass answer helps no-one. If you had bothered to read
the question you would see that I was asking about the behavior of
setTime() and not reporting a bug in javascript.
If you don't have an helpful answer why bother answering?

I read the question. I just didn't notice that you actually did have a
delay - since you didn't mention that - and so I was assuming that you
had a real bug somewhere, instead of just the expected behaviour - as
Ugo pointed out.
If you don't have an helpful answer why bother answering?
I did provide a helpful reply: without a good description of the
problem and the relevant code, we're all just guessing.

*Maybe*, and if, then only in this case. For example, you really do *not*
want to write
window.setTimeo ut(foo.bar, 1500);
even if foo.bar does not have named arguments. shuffleDoor() could be the
method of an object in the scope chain as well (you did not quote enough to
assess that without further hassle).

As Ugo has already explained. Maybe window.setInter val() with a branch
for cancelling in the callback function is an option.

When I add the setTimeout function I must be doing it wrong because

I want to use a setTimeout to just loop for a number of seconds, then
fall through to the next bit of code...can this be done by using some
kind of null in the statement, or do I have to assign the code a name
and call it from the setTimeout once it's done?
Thanks so much!

Is there a straightforward way of implementing a PHP equivalent to
window.setTimeout?
In a javascript web app, it's often the case that things are done on
an event driven basis. For example, html elements might have things
like onclick="buttonClicked()" to indicate that the function
buttonClicked should be run when that element is clicked.
The analogue can be done in PHP (on Windows) using com_event_sink. In
