Dynamically populate multiple input textboxes using jquery function , based on one input textbox

Question

I have an input textbox called idno. Based on an id number added to this textbox, i want to populate 3 other input textboxes using a jquery function that is functional.

<script>
$().ready(function() {
$('#idno').rsa_id_validator({
});
});
</script>
