Cookie counter junk in Chrome, how to cure?

Question

JavaScript

I'm learning php on the Specialist's video course. Now the lesson on cookies and I had a problem with them in the chrome browser.

$visitCounter = 0;
if(isset($_COOKIE['visitCounter'])){
$visitCounter = $_COOKIE['visitCounter'];
}
$visitCounter ++;

$lastVisit = '';
if(isset($_COOKIE['lastVisit']))
  $lastVisit = date('d-m-y H:i:s',$_COOKIE['lastVisit']);
setcookie('visitCounter', $visitCounter, 0x7FFFFFFF);
setcookie('lastVisit', time(), 0x7FFFFFFF);

Accordingly, visitCounter is displayed in the index (you have been so many times) and if in Mozilla and Opera the score is +1, then in Chrome +2 after each update. What could be the problem?

Answer 1

I think that the event should be hung not on the document, but on the input form itself
. should be something like this:
$('.text').on('input', function () {
clearInterval(timerPostAuthor);
});
Only in this case the execution of setInterval will stop. But, you can restart a new interval in the function of the same event

Answer 2

in the wrong CNC implementation
