怎样判断选择了单选框中的一个?

[kel]

选中了一个单选框,但怎样判断选中的是单选框中的具体哪一个?

[arclala]

function stateChecker() {
var checkedButton = ""
for (var i in document.musicForm.musicType) {
if (document.musicForm.musicType[i].checked=="1") {
checkedButton=document.musicForm.musicType[i].value
}
}
}

<script>
function CheckRadio(radioSelect)//判断单选框
{
for(var i=0;i<radioSelect.length;i++)
{
if(radioSelect[i].checked)
{
return (i+1);
break;
}
}
return "未选中"
}
</script>
<form name="frmTest">
<input type="radio" name="radioSelect" value="0">
<input type="radio" name="radioSelect" value="1">
<input type="button" name="cmdButton" value="submit" onclick="alert(CheckRadio(frmTest.radioSelect)">
</form>
