Information source: https://fly.layui.com/extend/step-lay/

Points to note: When clicking the next step in 1, it will refresh directly after clicking without sliding to the next step. A type="button" needs to be added, because the button button in the form defaults to type="" submit", you need to add attributes yourself to be a button, otherwise the page will be submitted and refreshed
