Javascript codeigniter未验证输入文本

我有一个密码更改表，提交时只有两个输入被验证，名为“确认新密码”的输入未被验证。我怎么了

请帮帮我

HTML和JS代码

$(function($) {
    $.fn.ajaxForm = function(url, data, msgHolderId) {
        var self = this;
        var result;
        return $(self).bind('submit', function(e) {
            e.preventDefault();
            if (data != null)
                data = "&" + $.param(data);
            alert(data);
            $.ajax({
                url: '<?= base_url() ?>' + url,
                async: false,
                cache: false,
                data: $(self).serialize() + data,
                type: 'POST',
                dataType: 'json',
                success: function(response) {
                    $('#' + msgHolderId).html(response.msg);
                }
            });
        });
    }
}(jQuery));

$(document).ready(function() {
    $('#password-change-form').ajaxForm('user/settings/password_change', null, 'msg-holder');
});

试试这个

$this->form_validation->set_rules('password', 'Password', 'required|matches[confirm-new-password]');
$this->form_validation->set_rules('confirm-new-password', 'Password Confirmation', 'required');

请尝试以下代码：

$this->form_validation->set_rules('current_pwd', 'Current password','required');
$this->form_validation->set_rules('new_pwd', 'New password' ,'required|min_length[6]|max_length[20]');
$this->form_validation->set_rules('confirm_pwd', 'Confirm password','required|matches[new_pwd]');

然后更改输入名称

$this->form_validation->set_rules('password', 'Password', 'required|matches[confirm-new-password]');
$this->form_validation->set_rules('confirm-new-password', 'Password Confirmation', 'required');

$this->form_validation->set_rules('current_pwd', 'Current password','required');
$this->form_validation->set_rules('new_pwd', 'New password' ,'required|min_length[6]|max_length[20]');
$this->form_validation->set_rules('confirm_pwd', 'Confirm password','required|matches[new_pwd]');
