<table>
 <c:forEach items = "${userData}" var = "userData">
 
     <tr> 
     <td> $ {dob} </td > </tr>   
     <!--need to calculate age based on dob in jquery -->
     <tr> <td><span> $ {age}</span></ td>< /t >
 </c:forEach>
</table>

function calculateAge(){
}

How I can call calculateAge() function on row 2 ?
