| Form | | public class Form extends ClosingUIBean (Code) | |
Renders HTML an input form.
The remote form allows the form to be submitted without the page being refreshed. The results from the form
can be inserted into any HTML element on the page.
NOTE:
The order / logic in determining the posting url of the generated HTML form is as follows:-
-
If the action attribute is not specified, then the current request will be used to
determine the posting url
-
If the action is given, Struts will try to obtain an ActionConfig. This will be
successfull if the action attribute is a valid action alias defined struts.xml.
-
If the action is given and is not an action alias defined in struts.xml, Struts
will used the action attribute as if it is the posting url, separting the namespace
from it and using UrlHelper to generate the final url.
Examples
<s:form ... />
