Hiding a radio button

[xara]

Hi,

I need to call a javascript function to hide a radio button in my form. The function is called from somewhere in my form. How can I do that.
<input type=radio name="switch" value="fisrt">
<input type=radio name="switch" value="last">


Thanks

<input type=radio name="switch" value="fisrt">
<input type=radio name="switch" value="last">


<input type=radio name="switch" value="fisrt" onClick="this.form.last.style.display='none';">
<input type=radio name="switch" value="last" onClick="this.form.last.style.display='none';">
