Thanks to @Mohit, I guess you're talking about pop up boxes? There are three type: > alert() to just show a message to user, waiting for validation (only one buttons: ok) > confirm() to display a message and get a boolean user response (two buttons: ok/cancel) > prompt() wich display a message and expect a value (string) from user (two buttons: ok/cancel) https://www.w3schools.com/js/js_popup.asp
