Summary
In this chapter, we have learned the following:
• Forms are the primary method used for entering data into a browser.
• Forms have a variety of controls that are used for entering different types of inform-
ation.
• HTML5 has a large number of new input types that are beginning to be implemented
in modern browsers.
•
document.forms
will return an HTML collection of all the forms on a page.
•
form.elements
will return an HTML collection of all the elements contained
within a form.
• Forms have
focus
,
blur
, and
change
events that fire as a user interacts with the
form.
• Forms also have a
submit
event that can be used to intercept a form before it has
been submitted.
• The information entered into a form can be read or updated using the
value
prop-
erty of the form controls.
• The HTML5 form validation API can be used to automatically validate a form, but
only at a basic level, so a custom validation script may be required.
In the next chapter, we'll look at the
window
object.
