我正在研究Struts 2应用程序，我正在尝试为10位数的移动电话号码提供验证。
我只允许10位数字但是即使我输入10位数字它仍然显示验证错误消息并且还想知道是否有任何方式购买我们可以执行验证日期时间选择器DOJO标签。

答案 0 :(得分：0)
使用stringlenth验证程序可以验证字符串的长度。查看stringlength validator。
使用date验证程序，您可以验证日期格式。查看date validator。
如果要使用validate()验证日期时间选择器，如果不使用{{3}等其他日期时间库，则应使用SimpleDateFormat解析选择器返回的值的逻辑。然后你应该为日期时间创建ThreadLocal解析器。
