How to set radio button status with JavaScript

Question

What method would be best to use to selectively set a single or multiple radio button(s) to a desired setting with JavaScript?

Answer 1

/**
 * setCheckedValueOfRadioButtonGroup
 * @param {html input type=radio} vRadioObj 
 * @param {the radiobutton with this value will be checked} vValue 
 */
function setCheckedValueOfRadioButtonGroup(vRadioObj, vValue) {
    var radios = document.getElementsByName(vRadioObj.name);
    for (var j = 0; j < radios.length; j++) {
        if (radios[j].value == vValue) {
            radios[j].checked = true;
            break;
        }
    }
}
