Name
radio — NN 2 IE 3 DOM 1
Synopsis
The radio
object
is a form control generated with an INPUT
element
whose TYPE
attribute is set to
"radio"
. radio
objects related
to each other are assigned the same name. This means all like-named
radio
objects become a collection of radio
objects. It may be necessary, therefore, to reference an individual
radio button as an item in an array. The entire array, of course, has
a length
property you can use to assist in looping
through all radio
objects within the group, if
necessary:
var radioGrp = document.forms[0].myRadio for (var i = 0; i < radioGrp.length; i++) { alert("The value of button index " + i + " is " + radioGrp [i].value) }
Properties and methods listed as follows are for individual radio buttons.
