         // Here you can initialize the app
         var myApp = new Framework7();
         // If your using custom DOM library, then save it to $$ variable
         var $$ = Dom7;
         // Add the view
         var mainView = myApp.addView('.view-main', {
            // enable the dynamic navbar for this view:
            dynamicNavbar: true
         });
         $$('.indicator_modal').on('click', function () {
            myApp.showIndicator();
            setTimeout(function () {
               myApp.hideIndicator();
            }, 1500);
         });
      </script>
