checkbox to wipe out radiobuttons 1

[Sniipe]

		<tr>
			<td>Are you happy?</td>
			<td><input type="radio" name="2"  value="4" can_run="true"/></td>
			<td>Yes</td>
			<td><input type="radio" name="2"  value="5" can_run="true"/></td>
			<td>No</td>
			<td><input type="checkbox" name="2" checked/></td>
		</tr>

I'm creating the above code dynamically. What would I have to enter for an onclick so that when the checkbox is ticked that the yes/no radio button would be unticked (currently above it shows neither radiobutton checked)

Sadly there is no clearing function of that nature, you would need to create your own.

But if done correctly you can use it with all your radio buttons, regardless of how many each same-named group may have.

<script>
function ClearRadios(radios_name){
var radios=document.getElementsByName(radios_name);

for(var i=0; i<=radios.length-1; i++){

radios[i].checked=false;
}


}

</script>


<input type="checkbox" name="2" checked/ onClick="ClearRadios('2');">

cool, thanks Phil,

Its good but I think I need it to only work for radio buttons. Can I get getElementsByName and then dig down into that and get them by type?

Sure, you can look for the ones who's type is radio.

for(...)
  if(radios[i].type=='radio'){
    radios[i].checked=false;
  }

}
