请问如何在表单里更新错误信息？

        <form class="ui large form">
            <div class="ui stacked segment">
                <div class="field">
                    <div class="ui left icon input">
                        <i class="user icon"></i>
                        <input type="text" name="email" placeholder="E-mail address">
                    </div>
                </div>
                <div class="field">
                    <div class="ui left icon input">
                        <i class="lock icon"></i>
                        <input type="password" name="password" placeholder="Password">
                    </div>
                </div>
                <div class="ui fluid large teal submit button">Login</div>
            </div>
            <div class="ui error message" id="sdgajsgdkjhaskj"></div>
        </form>

是这样的，我照着官方给的实例做的登录界面，这里有对输入信息的检查

                            password: {
                                identifier: 'password',
                                rules: [
                                    {
                                        type: 'empty',
                                        prompt: 'Please enter your password'
                                    },
                                    {
                                        type: 'length[6]',
                                        prompt: 'Your password must be at least 6 characters'
                                    }
                                ]
                            }

这些检查不过过的话，会在<div class="ui error message"></div>这里显示
我是用ajax做的提交，想在提交后更新这个error message
但是没找到办法
直接对这个div使用正常的手段也没有作用
