Hi @ all!
I need a little help. I developed a module, which will send a form with post and the target file will save some data in the SQL database and send an email to the customer. Everything works fine, but unfortunately that takes 5 or 6 second.
I saw a nice bootstrap solution here: https://codepen.io/jmalatia/pen/HkmaA
But I can't get it to work in my phtml file. The button changes only if the target page is loaded (I can see that by using the back-button), but he should change, and the the action should start.
Can somebody help me? Or give an alternative?
