To pass a parameter form one jsp page to another using Onclick

I need to pass the id parameter from task.jsp to edit.jsp.

I tried using the set and get parameter with input type as hidden, but was unable to get the id in the edit.jsp

This is a part of my task.jsp page

<tr> <%-- <td><%=currentTask.getId()%></td> --%> <td><%=currentTask.getTaskDescription()%></td> <td><%=currentTask.getDate()%></td> <td><%=currentTask.getUser().getUserName()%></td> <td><input id="<%=currentTask.getId()%>" type="button" onclick="editAction(this)" value="Edit" /></td> <td><input id="<%=currentTask.getId()%>" type="button" onclick="deleteAction(this)" value="Delete" /></td> </tr> <% } %> </table> </div> <p /> <input type="button" onclick="window.location='/HibeateWebApp/login.jsp';" value="Logout"> <% System.out.println(userName); %>
</form>
<b><a href="CreateTask.jsp?userName=${userName}"> Click here to add a new task </a></b>
<script> function editAction(item) { int id = item.id;
</script>
<input type="hidden" name="id" id="id" />
<script> document.getElementById("id").value = id; document.form.action = "edit.jsp"; document.form.submit(); console.log(item.id); }
</script>
<script> function deleteAction(item) { console.log(item.id); }
</script>

This is the error I get in my console when I click on the edit button - ReferenceError: editAction is not defined

How do I pass the parameter from task.jsp and get it is edit.jsp
