If there is only one <input type="radio" name="radioName" value="value1"> words,
document.forms [0] . radioName.value radio can be taken to the value of value1.
If there are multiple radio,
<input type="radio" name="radioName" value="value1">
<input type = "radio" name = "radioName" value = "value2">
that document.forms [0]. radioName is actually an array,
var test = document.forms [0]. radioName;
var len = test.length;
for (var i = 0; i < ; len; i + +) {
if (test [i]. checked == true) {
alert (test [ i]. value);
} to get you selected a single marquee value.
