JavaScript form Object

• JavaScript has a form object to deal with forms.
• It is an attribute of the document object.
• There are two ways to access the form object:
• By name: document.formName
• By array: document.form[n]
• The form object has properties:
• action - same as ACTION in form tag; where the information will be submitted.
• encoding - MIME type, text, image, etc.  You probably won't need this.
• length - Number of elements on form.  You can use this later when accessing the elements.
• method - GET, POST, or other.
• target - window in which the results will be displayed.
• It also has methods, just like the two default button types in a form:
• submit() - submits the form to the ACTION URL via the POST method.
• reset() - clears all fields.
• And event handlers
• onSubmit - called when form is submitted by user.  How could you use this?
• return true to allow form to be submitted,
• false to prevent submission.
• onReset - called when form is reset by user.  How could you use this?
