Hi Phil-man and welcome to the sitepoint section where the user's machine does the work :)
I see you already realize radio buttons are maintained internally as arrays. I presume you also know that forms are also and that their field elements have the following attributes: name and type.
That said, here's an off-the-top possible solution:
for (i = 0 ; i < length ; i++)
if (elements[ i ].type == 'radio')
for (j = 0; j < elements[ i ].length; j++)
theVal = elements[ i ][j].value;
1)the with() method is a lazy coder's dream. It tells the browser that any questionable DOM elements that follow should be prefaced with the DOM in the parentheses (in this case, formObj -- document.formname, eg.)
2) Because of with(), length means formObj.length; elements = formObj.elements
3) If you have more than one group of radio buttons, you will have to add an additional conditional -- one that checks the radio group's name -- eg: if (elements[i].name = "Group1Buttons")
Edit Note: I had to edit the response to add spaces in the code "[ i ]" so that the bulletin software doesn't mistaken it for italics.
Hope this helps. If not, let me/us know and I/we will see what can be done.
