Check A Radio Button Based On Drop Down

in Using jQuery • 12 years ago

So I have a dropdown box and when a certain option is pressed will show other fields... if not they stay hidden.

However, I also need it to check a radio button that should remain showing.

Right now I have

<script type="text/javascript">
$(document).ready(function(){
$(".dnuHide").hide();
$(".dnuHide input").attr("disabled","disabled");
// If option Other is selected for institution type, show text field for Other
$("#region").change(function() {
var val = $(this).val();
$(".dnuHide input").attr("disabled",(val=="DNU")?"":"disabled");
(val=="DNU")?$(".dnuHide").show():$(".dnuHide").hide()
});
});
</script>

how would I modify that so I can also have ()Option 1 (*)Option 2 (already checked) change to (*)Option 1 ()Option 2

Hi,

Use the below code,

<script type="text/javascript">
$(document).ready(function(){
$(".dnuHide").hide();
$(".dnuHide input").attr("disabled","disabled");
// If option Other is selected for institution type, show text field for Other
$("#region").change(function() {
var val = $(this).val();
if(val=="DNU"){
$(".dnuHide input").removeAttr("disabled");
}
else {
$(".dnuHide input").attr("disabled","disabled");
}
(val=="DNU")?$(".dnuHide").show():$(".dnuHide").hide()
});
});
</script>

Thank you.
