Struts1.2.4学习心得!(四)

第四次学习:

这次学习碰到了与struts1.1很不同的地方,就是ActionForm类不仅仅是String型,可以是任意数据类型了.

1.表单录入(含bean的嵌套).

设有一个testBean类,这个类中又含有一个nested属性(nested为一个类的实例),当要为nested类的booleanProperty属性设定值时用nested.booleanProperty指定位置.下面例子录入数据时,数据填充到testBean和nested中去.

[table=90%][tr][td]java代码: [/td][/tr][tr][td]<div style="">
1
2   <%@ taglib uri="/tags/struts-bean" prefix="bean" %>
3   <%@ taglib uri="/tags/struts-html" prefix="html" %>
4   <%@ taglib uri="/tags/struts-logic" prefix="logic" %>
