Javascript timer

Hi experts,

I’m looking for a simple way to set a JavaScript timer to pull content from the server session every few minutes to keep the session active only while the browser window remains open.

Thanks for your comments,

look into setInterval

Hi,

You have many ways to call server side code from JavaScript!

JavaScript - http://www.aspsnippets.com/Articles/Calling-server-side-function-from-JavaScript-in-ASP.Net.aspx

jQuery - http://www.codeproject.com/Articles/238866/Invoke-Server-Methods-From-Client-Side-Using-JQuer

ASP.NET - http://msdn.microsoft.com/en-us/library/ms178208.aspx

Calling JavaScript function at Particular intervals - http://www.w3schools.com/jsref/met_win_setinterval.asp

Hope it helps u...

The example at w3schools isn't what I'd use. They pass a String reference to a function in the setInterval call - I'd do it like this:

<html>
<body>
<input type="text" id="clock" />
<script type="text/javascript">
var int=window.setInterval(
function(){
var d=new Date();
var t=d.toLocaleTimeString();
document.getElementById("clock").value=t;},1000);
</script>
<button onclick="int=window.clearInterval(int)">Stop</button>
</body>
</html>

Open in new window

Why, you ask? Because passing a String of code - or function name - to either setTimeout or setInterval is tantamount to using the evil eval statement.

Thanks for your comments,

In fact I would like to every 9 minutes execute a function call “Submit”

Could you help me with the syntax?
