I want to check when someone tries to refresh a page.
For example, when I open a page nothing happens but when I refresh the page it should display an alert.
Store a cookie the first time someone visits the page. On refresh check if your cookie exists and if it does, alert.
function checkFirstVisit() {
if(document.cookie.indexOf('mycookie')==-1) {
// cookie doesn't exist, create it now
document.cookie = 'mycookie=1';
}
else {
// not first visit, so alert
alert('You refreshed!');
}
}
and in your body tag:
