Javascript function to reload a page every X seconds?

Question

A couple of questions:

I've never really used JS listeners other than onclick and onkey events, so I wondered if someone could help me with what I need in order to reload the page every X seconds?
Secondly, the page contains bare minimum, literally just one input box. Do I still need to include the html head and body?

You don't need Javascript for this simple function. Add in the page header:

<meta http-equiv="Refresh" content="300">

300 is the number of seconds in this example.

To reload the page after 5 seconds (5000 milliseconds) using JavaScript, add the following to the bottom of the page:

<script type="text/javascript">
  setTimeout(function () { location.reload(true); }, 5000);
</script>

As Greg Hewgill notes, you can also accomplish this with the meta refresh tag:

<meta http-equiv="Refresh" content="5">

Strictly speaking, you do still need <html> and <body> tags. Some browsers may render the page correctly without them, but your are safest to include them.

The java script option gives me an error: `Uncaught ReferenceError: settimeout is not defined ` – Zapnologica Feb 28 '14 at 07:35

@Zapnologica: the second 't' in `setTimeout` is capitalized. – pkaeding Mar 02 '14 at 23:33
Very important that if you want it to refresh every X seconds, you will need to use the setInterval(function(){}, X); not setTimeout(), where the anonymous function in setInterval is run every X miliseconds – namore Nov 20 '19 at 17:19
