how to make onchange in s:select to submit a form and call a specific
method in one action class
Good morning,
In struts2.2.3, how to submit a form to a predefined action?
For example,
(1) a.jsp
<s:select onchange="changeProcess" />
(2) Process.java
...
public String change()
{
get Form values from a.jsp
database actions ... ...
return a.jsp;
}
I'd like to know:
===========================
When values changed in s:select, how to submit the form and call
change() method in Process.java
Thanks lot!
Emi

You could always make your own tag as an extension to the standard struts select tag adding attributes onChangeAction and onChangeTarget and let your new tag render an appropriate bit of javascript to make an ajax call to the server and then populate the results into the target item.. such a set of tags in your jsp may look like
<myTagLib:select name="country" onchangeAction="regionsForCountry" onChangeTarget=" region" />
< myTagLib:select name="region" onchangeAction="countiesForRegion" onChangeTarget=" county" />
< myTagLib:select name="county" />
This would be a handy feature in a new struts tag to be fair, perhaps an <s:dynamicSelect>...

No chance without javascript. There is no struts on board functionality providing that feature.

Or someone could provide more info will "sj:select" help satisfy the
following requirement?
(1) <sj:select name="country" onchange="to_change_region" />
(2) <sj:select name="region" onchange="to_change_city" />
(3) <sj:select name="coutry" />
Actually, I prefer not to use complex javascript code to do change
select1, select2 is updated, change select2, and select3 is updated.
Thanks a lot!

The onchange attribute expects JavaScript. So you'd have to write a
function to use ajax to make your request to /process_change.action.
