HTML DOM Checkbox Object

Checkbox Object

The Checkbox object represents a checkbox in an HTML form.

For each instance of an <input type="checkbox"> tag in an HTML form, a Checkbox object is created.

Checkboxes let a user select one or more options of a limited number of choices.

You can access a Checkbox object by searching through the elements[] array of a form, or by using document.getElementById().
