get checkbox value to javascript from SQL output

I asked a question last week that turned out to be entirely my mistake in a section I assumed to be correct, but once the primary issue was resolved I am still left unable to get my line variable to my Javascript code. I have no actual experience with Javascript unfortunately and all tutorials or answered questions I find only show me how to get a specific checkbox to my Javascript, not one from a variable line.

Here is what I am trying to do, I have a report running with PHP from my SQL server database which reports every item without a sent date, this could be hundreds of items at a time, each line has some information about the unsent item and a checkbox, the checkbox has an "onclick" event to call my Javascript, which calls a PHP page and writes a sent date to the database for that item.

The current code works if I hard code an EID into my PHP link, so everything except passing a variable has been tested and works. Here is my code:

PHP

while($row = sqlsrv_fetch_array($result)) {
   echo "<tr>
   <td><a href='vieweid.php?EID=" . $row['EID'] . "'>view</a></td>
   <td><input type='checkbox' onclick='issent(this)' name='sent[$i]' value='" . $row['EID'] . "'/></td>
   </tr>";
   $i++;
}

Javascript:

<script type="text/javascript">
  function issent(cb){

    if($(cb).is(":checked"))
      {
      var jsEID = $(this).val()
      $.getScript("sentscript.php?EID="jsEID);
      }

    }
</script>

I'm not certain if the variable is not being filled in JS or if I'm calling it incorrectly as part of my $.getscript. Any help would be appreciated.
