Hello,
I solved the DOM problem. While the dynamically generated radio buttons
could not be read by their name attribute, they could be read by their
id attribute. I had mistakenly capitalized the D at the end of
"getElementById." Below is an adaption of a script from page 749 of the
second edition of O'Reilly's "Dynamic HTML: The Definitive Reference"
that can read these buttons.
<script type="text/javascript">
function read_multi(elementName, count){
for(var i = 0; i < count; i++) {
var a_button = document.getElementById(elementName + '_' + i);
if(a_button.checked){
alert('The value of the chosen button is ' + a_button.value);
}
}
}
</script>
Thank you for taking the time to read this topic.
