Multipule Linked Radio Buttons

Alex Walters Mar 27, 2002

This script links multiple arrays of radio buttons. Each button can only be picked once. Works in both Netscape and MSIE.

The JavaScript Source: Buttons: Multipule Linked Radio Buttons

Simply click inside the window below, use your cursor to highlight the script, and copy (type Control-c or Apple-c) the script into a new file in your text editor (such as Note Pad or Simple Text) and save (Control-s or Command-s). The script is yours!!!

<!-- TWO STEPS TO INSTALL MULTIPULE LINKED RADIO BUTTONS:

1.  Copy the coding into the HEAD of your HTML document

2.  Add the last code into the BODY of your HTML document  -->

<HEAD>

<!-- Begin

function disabler1() {

if(document.form.a[0].checked) {

document.form.c[0].checked=false

document.form.b[0].checked=false

}

if(document.form.a[1].checked) {

document.form.c[1].checked=false

document.form.b[1].checked=false

}

if(document.form.a[2].checked) {

document.form.c[2].checked=false
