calculate from the user confirm message

In the "Javascript onload" event, you can show the confirm message when a field loses the focus. If the OK button is clicked, the remaining fields are calculated automatically.

calculate code must be php.
echo "<script>if (confirm('Do you want to calculate this record?'))

</script>";
