Answer 1

设置按钮的checked属性:

function getConfirmation()
{
    var retVal = confirm("Your Level of Entry is A2, is this correct?");
    if (retVal)
    {
        alert("Your Level of Entry is A2!");
        return true;
    } 
    else
    {
        document.getElementById('radioButton').checked = false;
        return false;
    }
}
