In the jsp, I have two tables for two different type of users (administrator and secretary) to view. Those tables has checkbox for download multiple files.
I have a strange (I think) situation which is only one type of user (administrator) can check all checkboxes by click the checkbox near the first table column.
I would like to show you the code about those table first.
<script type="text/javascript">
$(document).ready(function() {
$("#clickAll").click(function() {
    if($(this).is(':checked'))
       {
         $("input[name='chkdownload']").each(function() {
             $(this).attr("checked",true);
         });
       }
       else
       {
         $("input[name='chkdownload']").each(function() {
             $(this).attr("checked",false);
         });           
       }
    });
});
var countChecked = function() {
    var n = $( "input:checked" ).length; 
    if (n == 0) { 
        alert("Please click at least one record.");
        return false;
    } else {
        return true;
    }
}; 
</script>
<div class="content">
<s:form namespace="/DownloadFile" action="download_getSelectedFile" method="POST" enctype="multipart/form-data">
<!--for administrator users to view -->
<div class="usrAdmin usrAccess" style="display:none">

  </display:table>
</div>
   <!--for secretary users to view -->
   <div class="usrSec usrAccess" style="display:none">
<!-- put row2 to make the table uid unique -->
<display:table name="${equipmentList}" class="its" uid="row2"

  <display:column property="equipLocation" title="Equipment Location" />
  <display:column property="equipOfficer" title="Equipment Officer" />
</display:table>
</div>
<input type="submit" value="Download Selected"/>
</s:form>
</div>
When I run the program, if I switch to secretary mode, I click the checkbox near the header column, it does not checked all checkboxes. It just shows a "tick" symbol in the checkbox only. However if I switch to administrator mode, I click the checkbox, it can checked all checkboxes.
At the beginning, I think maybe I mistype the incorrect name in jquery, but I review the code, both table are call the same input "chkdownload".
I have read the solution from this and this post, but I think my case is different to them.
Which part I did wrong in the code? It seems no typo error there. Otherwise, the checkbox in administrator mode will not work too.
Would someone let me know my mistake, please?
Update
I follow the instruction suggest by @reporter. I copy the html source code from Internet Explorer (IE). I see more code are generated and I would like to show it below for your review please. Thank you.

Update 2
For Secretary table, in jsp code, I put row2 for uid and in html source code I put row2 for id. I run the application, that table still cannot check all checkboxes whereas the other table works fine.
Although I have updated the code in the content, I extract the exact the code about the id part below for your quick review please. Thank you.
The code in jsp
<!--for administrator users to view -->
<display:table name="${equipmentList}" class="its" uid="row"
sort="list" pagesize="10" requestURI="equipment_view" export="false" defaultsort="1" defaultorder="descending">
 <!--for secretary users to view -->
<display:table name="${equipmentList}" class="its" uid="row2"
sort="list" pagesize="10" requestURI="equipment_view" export="false" defaultsort="1" defaultorder="descending">
The code in html source code
<!--for administrator  users to view -->
<table id="row" class="its">
 <!--for secretary users to view -->
 <table id="row2" class="its">
