will help you It turns out the problem was simple - the alert IS working, it just doesn't come before the default behaviour of submit, which includes a page refresh.
If you prevent the default from happening, you can validate and then decide what to do from there. Attached is a working snippet.
code :
$('#reminderForm').submit(function(e) {
  e.preventDefault(); // Stop your form from submitting.
  if ('0' === $('#reminderclosereason').val()) {
    alert();
    $('#errorInPopup').html('Please select close reason');
    return false;
  } else {
    this.submit();
  }
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div id="reminder" class="popup-layout">
  <form id="reminderForm" method="post">

To fix this issue I think the 'id should not same, but the 'name' can be same, then you can check with getElementById. You should able to add $i after 'id' to round up the element
code :
id="subject_opt<?php echo $i; ?>"
<script>
function checkSubjectAndGrade(num){
    for(i=0;i<2;i++){
        if(i!=num && document.getElementById("subject_opt"+num).value === document.getElementById("subject_opt"+i).value){
            alert("dropdown lists' value are same");
        }
    }
}
</script>
<form action="checkresult2.php">
    <table class="p1" bgcolor="#FFFFCC" bordercolor="#000000" align="center" width="771" border="2">
          <tr>
              <td><div align="center"><strong>No.</strong></div></td>
              <td><div align="center"><strong>Subject Name</strong></div></td>
