radio.defaultChecked
defaultChecked is a read-only Boolean property of the Radio object. It is true if the Radio button is initially selected--i.e., if the CHECKED attribute appears in the Radio's HTML <INPUT> tag. If this tag does not appear, then the Radio button is initially deselected, and defaultChecked is false.
You can use the defaultChecked property to reset a group of radio buttons 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 group of radio buttons with the following function:
function resetRadio(radio_group) {
var i;
for(i =index.html 0; i < radio_group.length; i++) {
if (radio_group[i].defaultChecked) {
radio_group[i].checked = true;
break;
}
}
}
