Writing Javascript for Validators
Hello All, I've written a new plugable validator rule, and now I'd like to write some javascript for it. Looking at the existing javascript for other validators, I see they all make a call like this: oRequired = new required(); which (in this case) gets all the required fields. I'm not sure what generates this method, but I can see it in my jsp when i put in html:javascript. my new rule is called futuredate. I don't know what sort of method I should call that will be like required(); but give me all the fields marked with furuterdate. How do I do this? Cheers __ Do you Yahoo!? Yahoo!

How do I do this?
Warning, I haven't done this before, but need to :
The validator-rules.xml and validator.xml file for your project have the
same format.
In --your-- validator.xml you can enter:
form-validation
global
validator name=futuredate
classname=com.matte.futuredate.validator.FieldChecks
method=validateFutureDate
methodParams=java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionErrors,
javax.servlet.http.HttpServletRequest
msg=errors.required
javascript![CDATA[
function validateFutureDate(form) {
...Your code
}
]]
/javascript
/validator
/global
I believe that all required
I don't believe you need to extend the StrutsJavaScriptTag.
Is that helpful at all ?

My question is this. In that Javascript code, I need
to validate the fields. How do I know what fields
need to validated? The javascript methods provided by
Struts for the other validators seem to call a method
that builds an array of all the fields in the form to
check, and then do a loop over that array.
(for example, the required validator makes a call to a
method called required()).
My question is what call should I be making? I don't
know how the required() method is being generated (it
isn't in the validation-rules.xml file, but it appears
in the code included by html:javascript. I'm going to
need something like a futuredate() method that builds
this array, but I don't know where I need to write it
(or how I tell struts to build it for me).
Does this make sense?
Cheers

RE: Writing Javascript for Validators
Matt, the required javascript method is generated in the
org.apache.struts.taglob.JavascriptValidatorTag class. The doStartTag
method (at line 305) builds the required javascript method (or any other
method that the form needs). Grab a copy of the Struts source and check it
out... should be very helpful.
Cheers,
Dan
