| 验证属性格式：<.......... check_str="控件名称" check_type="验证类型" can_empty="true" show_span="显示提示信息SPAN的ID">
| **check_type不为空则需要验证；check_type为验证类型；can_empty为true表示可以为空，默认不能为空；
| **show_span为显示提示信息SPAN的ID，默认为span+控件ID，repeat为true表示可以重复；
|
| **如果无类型，不写check_type，验证类型包括如下：
|	  用户名：useremail
|	  密  码：password
|   确认密码：confirmpassword （当为这个类型的时候，得加上确认对象ID属性confirm_id="password"）
|	电话号码：telephone
|	  手机号：mobile
|     字符串：string,10,20（string）
|     整数型：integer,-111,120（integer）
|     浮点型：float,-2.1,10000（float）

|     邮  件：email
|     身份证：idcard
