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?

Answer 1

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.
