Custom Javascript<script>
// Add parameter to the URL - demo helper function, not required in production
var setAutoOpenModalParam = function(set){
var currentUrl = window.location.href.split('?').shift();
var param = '?showModal=true';
window.location.href = set ? currentUrl + param : currentUrl;
}
// Get parameter to the URL - demo helper function, not required in production
var getUrlParameter = function(name) {
name = name.replace(/[\[]/, '\\[').replace(/[\]]/, '\\]');
var regex = new RegExp('[\\?&]' + name + '=([^&#]*)');
var results = regex.exec(location.search);
return results === null ? '' : decodeURIComponent(results[1].replace(/\+/g, ' '));
};
// Reference to the modal
var autoOpenModal = document.querySelector('#js-modal-advanced-auto-open');
// Calls modal 'show' method after a delay
var setAutoOpenModal = function(el) {
if (getUrlParameter('showModal')) {
setTimeout(function(){
el.show();
}, 3000)
}
}
// Callback on modal 'ready'
var onModalReady = function(e) {
setAutoOpenModal(autoOpenModal);
// IMPORTANT: remove this event listener unless you want it called each time the modal component renders
e.target.removeEventListener('modal:ready', onModalReady);
}
// Add 'ready' callback
autoOpenModal.addEventListener('modal:ready', onModalReady);
</script>
