Expose JsFunction property in ValidatorAction
---------------------------------------------
Key: VALIDATOR-262
URL: https://issues.apache.org/jira/browse/VALIDATOR-262
Project: Commons Validator
Issue Type: Improvement
Components: Framework
Affects Versions: 1.3.1 Release
Environment: Any
Reporter: Jeff Tsay
Exposing the JsFunction property in ValidatorAction would make it possible for
other tools to include Javascript routines as external scripts, inside of
inline Javascript in an HTML page. This would reduce the size of pages
containing client-side validation and the overall size of content transferred
from server to browser.
Shale commons validator integration uses commons validator to provide both
client side and server side mapping. When the JSF renderer writes the
validation Javascript code, it looks up the ValidatorAction for each validation
routine. It then inserts the Javascript inline using
ValidatorAction.getJavascript(). Since this code never changes and is likely to
be used multiple times, I would like to instead insert something like this:
<script src="/weblets/validator/validateEmail.js" />
I can almost do this with Shale commons validator and Weblets, but I need to
get the fully qualified resource name from the ValidatorAction, i.e.
JsFunction. I can then map the resource name
(com.ngweb.jsf.xul.validator.javascript.validateEmail) to a URL
("/weblets/validator/validateEmail.js") using Weblets.
The entire change required is adding:
/**
* Gets the fully qualified class path of the Javascript function.
* This is optional and can be used instead of the Javascript property.
*
* @return The Javascript function's fully qualified class path, or
* null if this property has not been set.
*/
public String getJsFunction() {
return jsFunction;
}
to ValidatorAction.java.
After the change above, I am able output <script src=""> tags in Shale commons
validator.
The change could also be used in other web frameworks to do the same thing.
