Question

My controller returns me a list of objects, which i render on a jsp. Whats i want to do is select a single row and mark it to be deleted.

But im not sure how to go about this:

I started with this:

  form
    table
        c:forEach var="book" items="${booklist}" 
            tr
                td>{book.id}</td
                td>{book.Number}</td
                td>{book.Address}</td
                td><input type="submit" name="delete" value="{book.id}" ..</td
            tr
        c:forEach>
    table>

(…apologies for formatting…)

I have two problems with the above, firstly it displays the id on the button. and secondly i still would ideally like to bind the selected row to a form so i can do some validation

any ideas?

Answer 1

I would wrap each row in it’s own form, with a hidden input holding the id of the book to delete:

<form>
    <input type="hidden" name="id" value="${book.id}"/>
    <tr>
        <td>...</td>
        <td><input type="submit" value="Delete"/></td>
    </tr>
</form>

Don’t forget your $s.
