I have got wrong alert! What is wrong? - radio-button

Question

I have a problem in revealing the actual results of the radio buttons. I use javascript to get value from radio button, succeeded anyway, BUT when I create a condition where if value! = "Yes" alert that appears why still "OK", I would like to choose if it is "No" means alert that should be appear is "NOT OKE ".
This is the form:
<form id="form_test" name="form_test" method="POST">
<input type="hidden" id="menu_id" name="menu_id" value="<?=$menu_id?>">
<table align='center' width='auto' class='table1' cellpadding='5' cellspacing="0">
<tr>
<td align='center' class='tabletitle'>No</td>
<td align='center' class='tabletitle'>PC</td>
<td align='center' class='tabletitle'>PN</td>
<td align='center' class='tabletitle'>PCO</td>
<td align='center' class='tabletitle'>GC</td>
<td align='center' class='tabletitle'>CUR</td>
<td align='center' class='tabletitle'>Codes</td>";
<td align='center' class='tabletitle'>Percent</td>";
<td align='center' width='5%' class='tabletitle'>Yes</td>";
<td align='center' width='5%' class='tabletitle'>No</td>";
</tr>
[call to database]
$num++;
echo " <tr>
<td class='tablecontent' align='center' valign='top'>$num</td>
<td class='tablecontent' valign='top'>$pc</td>
<td class='tablecontent' valign='top' nowrap>$pn</td>
<td class='tablecontent' align='center' valign='top'>$pco</td>
<td align='center' class='tablecontent' align='center' valign='top'>$gc</td>
<td class='tablecontent' align='center' valign='top'>$cur</td>
<td class='tablecontent2' valign='top'>$codes</td>";
<td align='center' class='tablecontent' valign='top'>$percent</td>";
<td align='center' class='tablecontent' valign='top'><input type='radio' id='yes' name='cek$num' value='yes' checked></td>";
<td align='center' class='tablecontent' valign='top'><input type='radio' id='no' name='cek$num' value='no' ></td>";
</tr>";
echo "
<tr>
<td><input type='button' name='accept' value='accept' onclick='getaccept()'></td>";
</tr>";
echo "</table>";
echo "<input type='hidden' id='jmlcek' name='jmlcek' value='$num'>";
echo "</form>";
Then this is the Javascript codes to get value:
<script language="Javascript">
function getaccept(){
//var str = '';
var elem = document.getElementById('form_test').elements;
var c = confirm("Yakin mau nerima?");
for (var i = 1; i <= elem.length; i++)
{
var e = elem[i].value
if (elem[i].type == "radio" && c)
{
if (e != "yes" && elem[i].checked){
alert('NOT OKE');
return false;
}else{
alert('OKE');
return true;
}
}
}
}
</script>
For example the amount of data that actually are three and all got selected "yes", when I select "no" at one of the existing number it will display alert "NOT OKE", but in fact when I select "no" the value I got was "yes" and alert up "OKE".
I have tried many times to make them correct but still the results are wrong, so what's wrong?
Thanks.

This is what I got:
function getApprove(){
//var elem = document.getElementById('form_test').elements;
var RadioButton = document.getElementsByTagName('input');
var Approve = confirm("Are you sure?");
for (var i = 0; i < RadioButton.length; i++)
{
if (RadioButton[i].type == "radio" && Approve)
{
if(RadioButton[i].checked && RadioButton[i].value != "yes"){
alert("NOT OKE");
return false;
}
}
}
for (var i = 0; i < RadioButton.length; i++)
{
if (RadioButton[i].type == "radio" && Approve)
{
if(RadioButton[i].checked && RadioButton[i].value == "yes"){
alert("OKE");
return true;
}
}
}

Thankyou so much p.campbell, for you concern and helping me m(_ _)m :)

What's happening here is that you're only evaluating the FIRST radio button because you've got a return statement in both those conditions in your (e != "yes" && elem[i].checked). It's exiting the function.
Remove your return statements near your alerts. They're exiting the function, and disallowing the loop to iterate through the form elements.
Here's a demo on JsBin.
