Struts form标签属性列表

Name

Description

action

form提交的目标地址，action用来选择一个Struts Action对提交后的客户请求进行处理。通过和action的path属性进行匹配来选择Struts Action。

如果在web.xml中设置的servlet映射是扩展名映射，则可以用以下方式进行Action匹配(扩展名可以不作为匹配内容)：

<html:form action="login.do" focus="accessNumber">

上面的语句表示form提交后，交给path属性值为login的Action进行处理

如果在web.xml中设置的servlet映射是路径映射，则action的值必须完全匹配Struts Action的path属性值，例如：

<html:form action="login" focus="accessNumber">

focus
