How to make a checkbox dim?

[joannyk]

Hi everyone,

I'd like to make a checkbox dim and disable it when click one of the radio buttons on a form. Is there any javascript function will make it? I've tried the blur() but it seemed that's not the suitable one.

Thank you!

Set the checkbox's 'disabled' property to true or false depending on whether you want the checkbox disabled or enabled. Like so:

[tt]
<form action=&quot;someaction.asp&quot; method=&quot;get&quot;>
<input name=&quot;checkboxSwitch&quot;
type=&quot;radio&quot; value=&quot;on&quot;
onclick=&quot;if(this.checked){document.forms[0].theCheckbox.disabled=false;}&quot;
checked>
Checkbox On<br>
<input name=&quot;checkboxSwitch&quot;
type=&quot;radio&quot;
value=&quot;off&quot;
onclick=&quot;if(this.checked){document.forms[0].theCheckbox.disabled=true;}&quot;>
Checkbox Off<br>
<input name=&quot;theCheckbox&quot;
type=&quot;checkbox&quot;
value=&quot;Some Value&quot;>
Enable and Disable This Checkbox using the Radio Buttons
</form>
[/tt]
