Class HtmlFormElement

java.lang.Object
  |
  +--com.raj.htmlForms.HtmlFormElement

Direct Known Subclasses:

HtmlInput, HtmlSelect, HtmlTextArea

public abstract class HtmlFormElement

extends java.lang.Object

This class will be the superclass of other form elements. It will hold attributes and methods that are common to all elements. This includes both <input> and <select> tags but excludes any attributes that are unique to a particular tag.

HtmlForms is capable of writing either HTML 4.01 Transitional or XHTML 1.0 Transitional. If you want to write to the strict versions of these DTDs, omit any attributes that do not exist in that DTD.

This class (FormElement.java) is part of the com.raj.htmlForms package that automatically generates HTML forms programmatically.
