<script>
function regist()
{
targetForm = document.forms[0];
targetForm.action = "login!regist";

}
</script>

struts.xml

...

<package name="lee" extends="struts-default">

<!-- 配置login Action,处理类为LoginRegistAction

<action name="zcw" class="com.zcw.LoginRegistAction">

<result name="input">/login.jsp</result>
<result name="error">/error.jsp</result>
<result name="success">/welcome.jsp</result>

<!-- 配置regist Action,处理类为LoginRegistAction
