This might be a bit of an odd request, but is there a fairly easy way to get a page to reload after a specified number of milliseconds? I've found one or two scripts with a lot of extra stuff I could cut out, however, they only start counting after the page loads, i.e. : window.onload=call_refresh_function

Afaik, there isn't a way to get a single page to start a timed refresh script before the page loads entirely...
However, if I were to create a page of frames, I could have a static frame (probably gonna end up a control bar in it) that has the script refreshing other frames without having to reload the script every time... Sound good so far?

Back to my question... The only scripts I've seen have a minimum "countdown" time of 1 second. Is there a way to get down to smaller increments than this?

Sidenote - It doesn't have to be pretty, it just needs to work And at the moment, it only has to work in MSIE6.

Put this in the head:

<scipt type="text/javascript">
setTimeout("this.location = 'url' ",1000)
</script>

That's for a one second refresh. Now it you put 1 instead of 1000, it will be 1 1000'th of a second. 500 for half a second and so on. Will work in any browser.

But um, why would you want a page to refresh before it's loaded? What's the point?

edit: oh change the URL bit to the URL of page to load.

If you're trying to foward the user, rather than refresh, then try

location.replace('newurl')

because that will prevent the current page from entering in the user's history (the back button will skip by it).

Hey that's cool. I hate it when my back button goes to an instant redirect page.

Maybe I'm being just a fool, but why not use the old meta-tag in order to do this?
<META HTTP-EQUIV=Refresh CONTENT="10; URL=http://www.whatever.com/"> might just do the trick.
That is, if you're planning to forward AFTER the page has been loaded.

See http://www.htmlhelp.com/reference/html40/head/meta.html for info on this.

I've updated the FAQ on this to reflect the advice given here:

How can I redirect a page with JavaScript?

The metatag equivalent is mentioned here:

How can I redirect a page with HTML?

Thanks everyone. I think Drac has what I'm looking for with: setTimeout("this.location = 'url' ",1000)
That oughta give me the start I need to get the rest of it together.

I knew someone would ask
I'm just trying to automate a rather trivial task of cycling through a few pages several hundred times. However, I don't need to load the entire page, graphics and all, it just needs to be long enough to send the info to the database and move on.


As for the META tag, I used something like that awhile back, and I seem to remember it waiting until the page loaded before refreshing/forwarding... However, I could be wrong.

Ok, in that case you'll want to put the script code just after the back end code that talks to the DB or it might fire x time after it reads post the head with could be bad.

Although, why can't you just set a loop statment in the server sider code to set the data into the databese?

Seems an awfully bizarre way to run a looping bit of code to me.

Like I said, "This might be a bit of an odd request."

Well, that would be a lot easier I suppose, however I'm not working with my pages, otherwise I would.

I was getting bored at school/work the other day and wanted to see if there was a way to do that. Actually, I knew there was at least one way, just wanted to see how involved it would be.

Thanks for the help everyone.

Let's just say this "project" is a bit of a Rube Goldberg pgae
