Struts2 -- interaction between JSP pages and actions

 

Variable value:

Output a variable value to the JSP page: <s: property value = "name"/>

 

<S: debug> dddd </s: debug>

Debug Struts2.0 page Parameters

 

 

<S: if test = "mgrLevel = false & exeLevel = false">

</S: if>

View plain

<Span style = "font-family: Microsoft YaHei;"> H 15:36:01

<S: if test = "mgrLevel = false & exeLevel = false">

</S: if> what does this sentence mean?

Where does mgrLevel variable come from?

Li 15:36:25

Er...

In the background action

H 15:36:31

JSP page does not seem to have a statement

Can I use it directly on the JSP page?

Li 15:37:04

Hmm

H 15:37:18

.... Sorry.

Li 15:37:32

No, as long as the get and set methods are available for backend properties.

Can be directly obtained in jsp

H 15:37:44

Oh .....

Li 15:37:46

This is struts2's advantage

H 15:37:54

<S: if test = "mgrLevel = false & exeLevel = false">

</S: if>

What does test mean?

Li 15:37:54

Struts1 won't work.

Test indicates the meaning of the test.

H 15:38:19

I have learned struts1.2 before.

Li 15:38:23

It's easy for you to understand it. It's the same as if.

H 15:38:29

Okay. Thank you. </span>
