javascript没有隐藏表单

默认情况下，此表单上的错误消息（'after'）应被隐藏，并且仅在用户按下"注册"提交按钮时显示。然而，所有的错误消息都是默认显示的——这有什么帮助吗？javascript文件正在打印到控制台，以便它可以找到该文件。我已经把表单的PHP和javascript放在下面了——任何帮助都将不胜感激，谢谢你，

这是PHP显示的表单：

<div class="span5 pull-right reg-form hidden">
    <?php
    echo $this->Form->create('Users.Register', array(
        'url' => '/register',
        'class' => 'span12 pull-right'));
    echo $this->Form->hidden('current_url', array('value' => $this->here));
    echo $this->Form->input('username', array(
        'class' => 'reg-input',
        'label' => array('text' => 'Email:', 'class' => 'reg-label main-color'),
        'div' => array('class' => 'span12 reg-div'),
        'required' => FALSE,
        'after' => '<span class="hidden show-email-err show-err">This email address is already taken</span>
            <span class="hidden show-emailvalid-err show-err">This email is not valid</span>'
    ));
    echo $this->Form->input('confirm_username', array(
        'class' => 'reg-input',
        'label' => array('text' => 'Confirm Email:', 'class' => 'reg-label main-color'),
        'div' => array('class' => 'span12 reg-div'),
        'required' => FALSE,
        'after' => '<span class="hidden show-user-err show-err">Re-email is incorrect</span>'
    ));
    echo $this->Form->input('password', array(
        'class' => 'reg-input',
        'label' => array('text' => 'Password:', 'class' => 'reg-label main-color'),
        'div' => array('class' => 'span12 reg-div'),
        'required' => FALSE,
        'after' => '<span class="hidden show-pass-long show-err">Password must be at least 6 characters</span>'
    ));
    echo $this->Form->input('confirm_password', array(
        'class' => 'reg-input',
        'type' => 'password',
        'label' => array('text' => 'Confirm Password:', 'class' => 'reg-label main-color'),
        'div' => array('class' => 'span12 reg-div'),
        'required' => FALSE,
        'after' => '<span class="hidden show-pass-err show-err">Re-password is incorrect</span>'
    ));
    echo $this->Form->input('firstname', array(
        'class' => 'reg-input',
        'label' => array('text' => 'Name:', 'class' => 'reg-label main-color'),
        'div' => array('class' => 'span12 reg-div'),
        'required' => FALSE,
        'after' => '<span class="hidden show-firstname-err show-err">This field must not empty</span>'
    ));
    echo $this->Form->input('lastname', array(
        'class' => 'reg-input',
        'label' => array('text' => 'Last Name:', 'class' => 'reg-label main-color'),
        'div' => array('class' => 'span12 reg-div'),
        'required' => FALSE,
        'after' => '<span class="hidden show-lastname-err show-err">This field must not empty</span>'
    ));
    ?>
    <?php echo $this->Form->end(array('label' => 'Register', 'div' => false, 'id' => 'RegSubmit', 'class' => 'btn-sign pull-right')); ?>
</div>

这是javascript：
