help in radio button

[Babu Singh]

i have four radio button in a row.
name and id is same of all four button in a row.
suppose, name and id for all buttons in first row is radiobutton0. for second row it is radiobutton1, for third row it is radiobutton2. thus i have 10 rows in a table.
my aim is when i submit the page, one button must be checked in a row else it show a msg box that please fill the corresponding radio button. .
i want to get the value of radio button either true or false.

i run the following code:

function get_radio_value()
{
var  radioID="radiobutton";
var radiobuttonName;
var radiobuttonValue;
   for (var i=0;i<10;i++) {
  radiobuttonName=radioID+i;
  alert("radiobutton Name is:"+:"+radiobuttonName);
}
}

this method execute the loop and display all radiobutton Names.
How i find radiobuttonValue which is either true or false.

thanks.
