I have to create complex submit form that uses several JavaScript features.Almost every web application has a submit form. For this assignment, we may choose any domain such as information inquiry, user registration, and online purchase, provided that your choice suggests enough details to.While the choice of domain and the details of the form are up to me, the resulting form should meet.The form must check at least one field for presence or valid format. If invalid, JavaScript should prevent the form from being submitted and provide a meaningful message to the user.The form must provide at least one optional field that only appears if it is appropriate for a previous selection. For example, a text area might appear only if the user first checks a box labeled.
