Help disabling radio buttons

[kajj]

Hi,

 

I have the following radio buttons:

 

<input type="radio" name="R5" value="1" checked> All<BR>

<input type="radio" name="R5" value="2"> Current<BR>

<input type="radio" name="R5" value="3"> Not Current<BR>

<input type="radio" name="R5" value="4"> Prior<BR>

<input type="radio" name="R5" value="5"> New<BR>

 

I am trying to disable them with no luck.  I am using the following function:

 

function ExternalData()

{

var the_box = window.document.form1.R32;

var the_switch = "";

if (the_box.checked == true) {

document.form1.R5.disabled = true ;

document.form1.R6.disabled = true ;

document.form1.R7.disabled = true ;

document.form1.R10.disabled = true ;

document.form1.R27.disabled = true ;

document.form1.R28.disabled = true ;

 

} else {

document.form1.R5.disabled = false ;

document.form1.R6.disabled = false ;

document.form1.R7.disabled = false ;

document.form1.R10.disabled = false ;

document.form1.R27.disabled = false ;

document.form1.R28.disabled = false ;

}

}

 

R10, R27, and R28 are checkboxes and dropdowns that disable correctly but I can't get the radio buttons to disable.  I'm fairly new to Javascript and I'm quite lost on how to do this.  Someone suggested using getelementbyid but everything I have looked at for that is a bit confusing.

 

Any help would be appreciated.

 

Thanks.

After much trial and error, I finally got this to work.  I added IDs to all of my radio buttons and added the following code to the top of my function:

 

document.getElementById('IDR51').disabled= checked;

document.getElementById('IDR52').disabled= checked;

document.getElementById('IDR53').disabled= checked;

document.getElementById('IDR54').disabled= checked;

document.getElementById('IDR55').disabled= checked;

document.getElementById('IDR61').disabled= checked;

document.getElementById('IDR62').disabled= checked;

document.getElementById('IDR63').disabled= checked;

document.getElementById('IDR71').disabled= checked;

document.getElementById('IDR72').disabled= checked;

document.getElementById('IDR73').disabled= checked;

 

It is now turning the buttons on and off as needed.
