并行阵列单选按钮

Question

所以我有一个带有提交按钮的名字单选按钮。选择并提交单选按钮后，将显示所选名称的信息。我怎样才能做到这一点？

到目前为止，我有这个：

            <script type="text/javascript">
    <!--
    var names_array = new Array();
    names_array[0] = 'Amanda';
    names_array[1] = 'Aivan';
    names_array[2] = 'Yman';
    names_array[3] = 'Tiffany';
    names_array[4] = 'Hannah';

    var phone_num = new Array();
    phone_num[0] = '655-1512';
    phone_num[1] = '546-4562';
    phone_num[2] = '964-5645';
    phone_num[3] = '687-5455';
    phone_num[4] = '659-6548';

    var address_array = new Array();
    address_array[0] = '285 Parr Street';
    address_array[1] = '345 Aberdeen Avenue';
    address_array[2] = '589 Seymour Street';
    address_array[3] = '1000 McPhillips Street ';
    address_array[4] = '548 Alfred Street';


    function openNewName()
    {
    var nm=prompt("Name");
    var ph=prompt("Phone Number")
    var add=prompt("Address")
    }

    function openNewNameInfo()
    {
    myWindow=window.open('','','width=300,height=150,top=200,left=500');
    output(nm + ph + add);
    }

    function choosenItem()
    {for(count=0;count<5;count++)
    {if (MyForm.names[count].checked)
    myWindow=window.open('','','width=300,height=150,top=200,left=500');
    }
    myWindow.document.write(?);
    }


    //-->


    </script>
    <form name="MyForm">
    <input type="radio" name="names" value="Amanda">
    <label>Amanda</label><br/><br/>
    <input type="radio" name="names" value="Aivan">

    <input type="radio" name="names" value="Hannah">
    <label>Hannah</label><br/><br/>
    <input type="button" value="Show Info" onclick="choosenItem()"><br/>
    </form>
