When you write the cookie to the browser, you need to specify an expiration date or a max age. However, note that max-age is ignored by Interent Explorer 8 and below. So if you're expecting to get usage from that browser, you can just rely on expires.
Example:
<script type="text/javascript">
function setMyCookie() {
var now = new Date();
var expires = new Date(now.setTime(now.getTime() + 60 * 60 * 1000)); //Expire in one hour
document.cookie = 'n=1;path=/;expires='+expires.toGMTString()+';';
}
</script>
And your button can call this function like so:
<input type="button" onclick="setMyCookie();">Set Cookie</input>
Note that I've also included the path to indicate that this cookie is site-wide.
You can read more about expiring cookies with the date or max-age here: http://mrcoles.com/blog/cookies-max-age-vs-expires/

This should probably be now.setTime(now.getTime() + 60 * 60 * 1000); //Expire in one hour document.cookie = 'n=1;path=/;expires='+now.toGMTString()+';'; } The value in expires is an integer; you want the updated Date in now – tgf Oct 29 '15 at 23:11

Thanks for the comment. I've updated the script to create a new Date object from now.setTime(). – villecoder Nov 02 '15 at 15:07

You can do:
onClick="setupCookie();"
function setupCookie() {
document.cookie = "n=1";
setTimeout(function() {
document.cookie = "n=0";
}, 3600000); // 1 hour
}

This would be dependent on the user staying on the site for an hour. If they navigate away from the page, the cookie's value will never be reset. – villecoder Sep 05 '13 at 14:02

On click you can call some javascript function and while creating cookie itself you can set expire time please refer this
