带有验证的已启用/已禁用按钮

Question

我有一个带有两个空字段（密码，newPassword）和长度验证（7个字符），大写，小写，数字的表单。

我已经开发了测试，并且在激活验证时无法启用“重置密码”按钮。该按钮仍然处于锁定状态。

我认为错误可能出在isValid中，并且没有出现适当的参数。

我的表单：

我的JSP代码：

div class="form-group has-feedback">
                        <input class="form-control passwordField" type="password" name="newPassword" id="newPassword" autocomplete="off" 
                            placeholder="<fmt:message key="es.sanitas.gid.enter.credentials.new.password.placehoder"/>" 
                            required pattern="(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{8,}"/>
                        <i class="material-icons md-18 form-control-feedback">lock</i>
                    </div>
                    <div id="passwordRules"></div>
                    <div class="form-group has-feedback" >
