The first column contains text identifiers for the fields. The second column contains the
<input/>
elements themselves. Each of these tags has an
id
attribute:
username
for the Username field and
email
for the Email field. This enables you to easily find the
<input/>
elements and get the text entered into
them.
The third column contains an
<a/>
element. These hyperlinks exist for the sole purpose of kicking
off Ajax requests. As such, they have a hash (
#
) in their
href
attributes, thus preventing the browser
from navigating to a different page (to be considered a valid, clickable hyperlink, an
<a/>
element
must have an
href
value). Each of these links has an
id
attribute that you'll use later in your
JavaScript code.
The remaining three rows in the table contain two password fields and the Submit button (the smart
form currently does not use these fields):
<!-- HTML continued from earlier -->
<tr>
<td class="fieldname">
Password:
</td>
<td>
<input type="text" id="password" />
</td>
<td />
</tr>
<tr>
<td class="fieldname">
Verify Password:
</td>
<td>
<input type="text" id="password2" />
</td>
<td />
</tr>
<tr>
<td colspan="2" class="submit">
<input type="submit" value="Submit" />
</td>
<td />
</tr>
</table>
</form>
The CSS in this HTML page consists of only a couple of CSS rules:
.fieldname {
text-align: right;
