This is the example of tracking progress form. It basically tracks the form completion. It has a Javascript code which runs while the user completes the form. It displays the message according to the percentage of completion of the form. The HTML consists of a simple form, which wraps the progress bar and progress message. Each FormControl is wrapped by class Field. Each field is marked with required, which makes it mandatory to fill the input field. Note the Select tag with options defined for CardMonth and CardNumber. At last, we have input with the class button. CSS style format is defined from body of HTML to the button at the bottom. In JS file attribute for the progress is checked and accordingly message and progress at a progress bar is set. Once the form is completed we can submit the form using HTTP “post” method.
