Dynamic HTML: The Definitive Reference

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.
