[SOLVED] Load Magnific Popup once every 15 days for new user

Load Magnific Popup once every 15 days for new user

I have a newsletter sign up form that I would like to load (popup) only one time every 15 days, otherwise it might get a bit annoying. I am currently using this jquery code to load the popup form when the page loads.

<div id="test-popup" class="white-popup mfp-hide">
Popup Form
</div>

<script>
jQuery(window).load(function(){
jQuery.magnificPopup.open({
items: {src: '#test-popup'},type: 'inline'}, 0);
});
</script>

This works fine when loading the form every time you access the page but I would like to limit this so new users see it once every 15 days. Not sure if the 15 days is best practice just something I came up with?

Solution

You can use localStorage to do this.

$(window).on('load', function() {
  var now, lastDatePopupShowed;
  now = new Date();

  if (localStorage.getItem('lastDatePopupShowed') !== null) {
    lastDatePopupShowed = new Date(parseInt(localStorage.getItem('lastDatePopupShowed')));
  }

  if (((now - lastDatePopupShowed) >= (15 * 86400000)) || !lastDatePopupShowed) {
    $.magnificPopup.open({
      items: { src: '#test-popup' },
      type: 'inline'
    }, 0);

    localStorage.setItem('lastDatePopupShowed', now);
  }
});

<div id="test-popup" class="white-popup mfp-hide">
  Popup Form
</div>
