Validator中javascript的使用
关键字: 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
