How do i pop message and set expire time to that message state stored in local storage?

Question

if(localStorage.getItem('popState') != 'shown'){
        $(function () {
            $('[data-toggle="popover"]').popover({
            content : "....."
        });
          $('[data-toggle="popover"]').popover('show');
        });
            localStorage.setItem('popState','shown')
}

I am using the method above to display popup message to user during page load, and disable the popup message to be displayed after load for second time. How can i make it auto pop out to the user after certain period of time? e.g. after user close the popup message then it will be displayed automatically after an hour.

您可以使用以下间隔：

const showPopup = function showPopup() {
  const lastShown = localStorage.getItem('popStateLastShown');
  const hasOneHourPassed = lastShown ?
    (Math.abs(new Date(lastShown) - new Date()) / 36e5) >= 1 :
    false;

  if (hasOneHourPassed || localStorage.getItem('popState') !== 'shown') {
    // Show popup

    localStorage.setItem('popState', 'shown');
    localStorage.setItem('popStateLastShown', new Date());
  }
};

// Run code immediately.
showPopup();

// Check again after an hour.
setInterval(showPopup, 36e5);
