Checkbox.defaultChecked Property
Name
Checkbox.defaultChecked Property---initial state of a CheckboxAvailability
Navigator 2.0, Internet Explorer 3.0
Synopsis
checkbox.defaultChecked
Description
defaultChecked is a read-only Boolean property of the Checkbox object. It is true if the Checkbox is initially checked--i.e., if the CHECKED attribute appears in the Checkbox's HTML <INPUT> tag. If this tag does not appear, then the Checkbox is initially unchecked, and defaultChecked is false.
Usage
You can use the defaultChecked property to reset a Checkbox back to its default state. You might do this when the user selects a Reset button in a form, for example. You can reset a Checkbox with the following function:
function resetCheckbox(checkbox) {
if (checkbox.defaultChecked) checkbox.checked = true;
else checkbox.checked = false;
}
