I need to display jquery popup only once with a function onload

Question

I need to display jquery popup only once with a function onload. This is my popup with a window.onload function delay and to addclass is-visible, however I'm looking to add a cookie function so the popup will only load once per browser or cache.

Any suggestions would be fantastic! - J query & html in code

    jQuery(document).ready(function($){

  window.onload = function (){
    jQuery(".bts-popup").delay(1000).addClass('is-visible');
    }

    //open popup
    jQuery('.bts-popup-trigger').on('click', function(event){
        event.preventDefault();
        jQuery('.bts-popup').addClass('is-visible');
    });

    //close popup
    jQuery('.bts-popup').on('click', function(event){
        if( jQuery(event.target).is('.bts-popup-close') || jQuery(event.target).is('.bts-popup') ) {
            event.preventDefault();
            jQuery(this).removeClass('is-visible');
        }
    });
    //close popup when clicking the esc keyboard button
    jQuery(document).keyup(function(event){
        if(event.which=='27'){
            jQuery('.bts-popup').removeClass('is-visible');
        }
    });
});

How to simple manage cookies, i think you can watch here: link

I think it's pretty simple (pseudo-code):

if (getCookie("popup") doesnt exist OR is set to 0)
  showPopup();
  setCookie("popup",1);
else
  destroyPopup();
endif

You can use this simple way to handle multiple popoups too.

If you use PHP, you can use $_COOKIE instead of a javascript function.

Hope it helps.
