Sorry, but your explanation was not very clear to me, but I think this is what you want:

HTML Code:

<html>
<head>
<script>
function fillinput(){
var d=document.getElementById('theholder');
var theradios=d.getElementsByTagName('input');

for (i=0;i<theradios.length;i++){
	if(theradios[i].type=='radio' && theradios[i].checked==true){
	v=theradios[i].value;
	v=v+'.';
	var oldv=document.getElementById('inputs').value;
	document.getElementById('inputs').value=oldv+v;
	}
}
}

function clearvalue(){
document.getElementById('inputs').value='';
}
</script>
</head>

<body>
<div id="theholder">
<form>

<input type="radio" name="r" id="r1" value="1" onClick="clearvalue();">radio 1<br />
<input type="radio" name="r" id="r2" value="2" onClick="clearvalue();">radio 2<br />
<input type="radio" name="r" id="r3" value="3" onClick="clearvalue();">radio 3<br />
<hr />
<input type="radio" name="r2" id="r4" value="4" onClick="clearvalue();">radio 4<br />
<input type="radio" name="r2" id="r5" value="5" onClick="clearvalue();">radio 5<br />
<input type="radio" name="r2" id="r6" value="6" onClick="clearvalue();">radio 6<br />
<hr />

The radio values added to this input's field value:<br />
<input type="button" value="click to add radio button values" onClick="fillinput();" readonly="readonly">
<input type="text" id="inputs" value=""><input type="reset">

</form>
</div>
</body>
</html>

PS:
I noticed you said radio ID not value...you can simply do this by changing the 'value' to 'id' in

HTML Code:

v=theradios[i].value;

i pass two values from the radio button , then pass to the function and split it to array like ; radio[0],radio[1] to read the value .actually the photo id i need it during i submit the form. so i split it in the asp script also.
