struts的validate问题，validation.xml问题validator-rules.xml

validator-rules.xml已经写好了常用的校验，你可以在这个文件里添加自己的校验方法

解决方案 »

  1.   

    正则表达式也可以看明白的（呵呵`~部分部分）象暗码一样。那ruler你用就是了 一定好用的。
     Validator中javascript的使用1.    在struts-config.xml中加入validator的plug-in.  <!-- Validator的配置-->  <plug-in className="org.apache.struts.validator.ValidatorPlugIn"><set-property property="pathnames"value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>  </plug-in> 2.在文件/WEB-INF/validation.xml中是我们要定义自己的验证规则 <form-validation>    <!-- ========== Default Global Definitions ===================== -->
         <global>
          <constant>
            <constant-name>userID</constant-name>
            <constant-value>^\d{5}\d*$</constant-value>
          </constant>
          <constant>
            <constant-name>password</constant-name>
            <constant-value></constant-value>
          </constant>
        </global>
        
    <!-- ========== Default Language Form Definitions ===================== -->
       
          <formset>        
            <form name="loginActionForm">
              <field
                    property="userID"
                    depends="required">
                    <arg0 key="login.jsp.prompt.username"/>
                 </field>
              <field
                    property="password"
                    depends="required,mask">
                    <arg0 key="login.jsp.prompt.password"/>
                <var>
                    <var-name>mask</var-name>
                    <var-value>^[0-9a-zA-Z]*$</var-value>
                </var>
             </field>
            </form>
                </formset>
        
    </form-validation>3.   在浏览器端使用JavaScript进行验证
