A function reference is the best way to do it, but not so much because of

I really need this
someone? please?..
Thanks for the reactions.
but now, how do I see if the var has been set. *I'm using 'intvarM' as
a var btw*
Because when I click a hyperlink, or button, it says the vasn't been
set.
which is weird because the loop does update my fields.
this is how i start an interval:
function joinRoomFunction
You probably shouldn't use 'int'. It may be a reserved word in
Javascript.
I suggest using a different variable name to be safe.

In this case you need to wrap the code inside the onclick in a
function:
onclick="function(){int=clearInterval(int);}"
although obviously better would be to use $.click to bind the event:
$('button#foo').click(function(){int=clearInterval(int);});
You will probably also want to check that the

Thanks, Alexandre, it's kind of you to say that.
About this code...

Let's break it down a little. It's exactly the same as doing:
var callback = window.datascape.move;
datascape.myInterval = setInterval( callback, 400 );

Hi Alexandre,

hi Dave,
thanks a lot for the feedback. The reason i'm not using the dom but
rather more "conceptual" objects is because the application is quite
complex, and its easier for my small brain to keep track of all
variables as object properties.

Whoops, I missed the original issue, which was that setInterval needs

So change this:

to this:

jQuery works best when the DOM element is at the center of the logic.
It seems like there are probably other parts to the code, but this

You should change 'move' to move (remove apostrophes).

Also from what I understand you're passing a string

does that work?

The setInterval() function can take a string (which is "evals") or a
"reference" to a function (which is the recommended way).
To invoke a function via setInterval/setTimeout with arguments what is
usually done to use an anonymous function/closure.
So something like:
slideshow_interval = setInt
Thanks, works!

My understanding is that setInterval is use for looping, cause once the time
expires it executes again. It's a delay.
Whereas setTimeout will not run again once the function is triggered.

The following will pop up an alert dialog EVERY 20 (2 milliseconds) seconds:

The following will pop up an alert dialog ONCE, AFTER 20 (2 ms) seconds:

In both examples, you are calling setInterval with a text string containing
code. This code is executed in the global context, i.e. outside any

In your first example, alertMe() is a global function, so the call succeeds.
In the second example, alertMe() is nested inside another functio

bject, and your function will pick up the new value on the next iteration
