+17 A:

window.setInterval(function(){
  /// call your function here
}, 5000);

+1 You seriously answered this like a second or so after it was asked!? I call foul! :)

I smell inside job..

Anthony Forloney 2010-01-31 07:34:46

Who says I can't refresh every 2 seconds :D

Doug Neiner 2010-01-31 07:34:54

If I did plan an inside job, I would do it so my rep wouldn't cap after the first upvote :P

Doug Neiner 2010-01-31 07:35:48

I wonder what happens when you reach your cap limit if someone tries to upvote you. Does that vote never reach your rep? I've never known.

Anthony Forloney 2010-01-31 07:41:19

It still counts toward your individual tag stats, but no, you never again see the rep on your total rep score. Whats worse, is if you got 10 upvotes, but only one counted, and then someone downvotes, you still lose the 2 points. Oh well, par for the course!

Doug Neiner 2010-01-31 07:43:45

I'll wait to +1 for your speedy answer to the question when your rep's not capped, in the meantime I will +1 your comment for being so informative to my question :)

Anthony Forloney 2010-01-31 08:08:02

To the downvoter, do you have an easier way?

Answer 2

+5 A:

you could register an interval on the page using setInterval, ie:

setInterval(function(){ 
    //code goes here that will be run every 5 seconds.    
}, 5000);

John Boker 2010-01-31 07:33:23

setTimeout runs once only.

Jonathan Sampson 2010-01-31 07:34:27

yeah i fixed it, trying to type too fast, knew it would be answered quickly :)

John Boker 2010-01-31 07:35:00

Your opening suggestion still references setTimeout :)

Jonathan Sampson 2010-01-31 07:35:46

well, thanks :) man it's late. need to stop trying to answer questions when tired.

John Boker 2010-01-31 07:48:34

You could always call `setTimeout` again from within the function....that's the way I used to do it >.< I guess it can't be an anonymous function then. Unless there's some sort of call_self() function I'm unaware of.

Mark 2010-01-31 08:24:21

@Mark Yup, that's how I do it when timing is not very critical, but a job needs to execute periodically.

Answer 3

+3 A:

Both setInterval and setTimeout can work for you (as @Doug Neiner and @John Boker wrote).
See here for some more explanation about both to see which suites you most and how to stop each of them.
