HTML form classes

The HTMLForm class represents an HTML form. This class allows you to:

• Add an element, like a button, hyperlink or HTML table to a form
• Remove an element from a form
• Set other form attributes, such as which method to use to send form contents to the server, the hidden parameter list, or the action URL address

The constructor for the HTMLForm object takes a URL address. This address is referred to as an action URL. It is the location of the application on the server that will process the form input. The action URL can be specified on the constructor or by setting the address using the setURL() method. Form attributes are set using various set methods and retrieved using various get methods.

Any HTML tag element may be added to an HTMLForm object using addElement() and removed using removeElement(). Use the following HTML tag element classes in your HTMLForms:

• FormInput classes: represent input elements for an HTML form
• LayoutFormPanel classes: represent a layout of form elements for an HTML form
• TextAreaFormElement: represents a text area element in an HTML form
• LabelFormElement: represents a label for an HTML form element
• SelectFormElement: represents a select input type for an HTML form
• SelectOption: represents an option for a SelectFormElement object in an HTML form
• RadioFormInputGroup: represents a group of radio input objects which allow a user to select one from a group

Of course, you can add other tag elements to a form, including the following:

• HTMLText
• HTMLHyperlink
• HTMLTable
