Use of single Form multi-picture submit button (submit) in Struts2

In a form within a Struts2 if there are multiple submit buttons, such as adding, updating, saving, etc.

These buttons use an action, call a different method, and perform a JavaScript check before calling.

How do I use this submit button?

After summing up the following:

First specify the namespace of the action in the form label header:

<s:form namespace= "/system/usermanager" >

The following calls are then:

<s:submit type= "image" Id= "find" value= "find" label= "Retrieve user information by specified criteria"
Src= "/issframe/images/btn/btn_find.jpg" cssclass= "Button_image"
onclick= "return checkinputforrequired ();" action= "User" method= "Dosearch"/>

The above is an example of a picture submission button, because the picture buttons are usually used in the project:

Execute JavaScript in the onclick, remember not to omit return.

Action is the name that you want to call the action that is defined in the STRUTS2 configuration file

Example: <action name= "user_*" class= "com.system.action.ManagerUserAction" method= "{1}" >

Note that no wildcard characters ("_" or "!") are included. , etc.).

Mothed is the corresponding method defined in the action class.
