Answer 1

Try this:

var radios = document.getElementsByTagName("input");
for (var i=0; i<radios.length; ++i) {
    if (radios[i].type == "radio" && /^favoritepreferred\d+/.test(radios[i].id) && /^favorite\d+/.test(radios[i].name)) {
        radios[i].checked = false;
        radios[i].removeAttribute("checked");
    }
}

Well you could add a class to your radio buttons and then select it easily with JQuery.

Alternatively you could use JQuery's attribute-starts-with-selector:

$("input[id^='favorite']").attr("checked", true);
