Start by using the correct input type, and adding
the pattern
attribute[
^] to your name inputs, so that the browser will validate them:
<input type="text" name="First Name" id="control_COLUMN1" label="First Name" class="textinput mandatory" placeholder="First name*" required maxlength="50" pattern="[A-Z]?[a-z]*(\s[A-Z][a-z]*)*" />
...
<input type="text" name="Last Name" id="control_COLUMN2" label="Last Name" class="textinput mandatory" placeholder="Last name*" required maxlength="50" pattern="[A-Z]?[a-z]*(\s[A-Z][a-z]*)*" />
...
<input type="email" name="Email" id="control_COLUMN3" label="Email" class="textinput mandatory" placeholder="Email*" required maxlength="50" />
Then, add the
jQuery Validation Plugin[
^] to your page and validate the form.
