[OT] form default submit button

[Erez Efrati]

Hi,
 
This not a struts issue though my project is well attached down to the
bones to struts.
I am a bit rusty in HTML and I need your advice.
I have a login form with username and password fields. The button is
built with a table consisting of the graphical edges and the text 
(retrieved from the resource bundle) in the middle.
 
What do I have to do so when the user is in the username field or
password and hits <ENTER> the form will submit. Currently it does not do
it and I have to click on the "table" button, whereas with buttons made
of <html:submit>.</html:submit> it worked automatically even with more
forms on the page where each works the same way autonomously. 
 
Here is the fragment of the button in my login form.
 
<-- Start Button -->
<div class="btn" onclick="LoginForm.submit();" style="margin-top:10px;">
      <table border="0" cellpadding="0" cellspacing="0">
            <tr>
                        <td class="btnRight">&nbsp;
                        </td>
                        <td class="btnText">
                                    <fmt:message
key="LoginForm.enterBtn"/>
                        </td>
                        <td class="btnLeft">&nbsp;
</td>
            </tr>
     </table>
</div>
<!-- End Button -->
 
 
Thanks in advance,
