Javascript function to reload a page every X seconds?
A couple of questions:
I've never really used JS listeners other than
onclickandonkeyevents, 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开发者_开发知识库, literally just one input box. Do I still need to include the html
headandbody?
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.
use a timer: http://www.elated.com/articles/javascript-timers-with-settimeout-and-setinterval/ and usee ajax to reload if it is dynamic
