ft:form-template onSubmit issue
Hi,
I have a cform which has javascript validation on some form fields
(widgets):
<fd:javascript>
if (case) {
return true;
} else {
return false;
}
</fd:javascript>
<fd:widgets>
</fd:widgets>
Basically what I want to happen is that when <form> is returned a value of
'true' to indicate that all form fields have been validated successfully a
javascript function is carried out, for example an alert is triggered
alert("success").
I have edited both resources/forms-lib.js and resources/forms-
field-styling.xsl and absolutely nothing is happening. Firstly how can I
determine in javascript whether true has been returned to the form after it
has been submitted? I have tried a check on document.Form.submitted and had
no joy with that. Any ideas?
regards
Andrew

After a few hours sleep! I have refined my dojo code, which is still not
playing ball. What gives here?:
<script>
dojo.require("cocoon.ajax.BUHandler");
function formProcessing() {
alert("Your details are being processed. Please wait");
}
function getResults() {
var proto_Type = cocoon.ajax.BUHandler.prototype;
dojo.event.connect(proto_Type, "processResponse", "formProcessing");
}
dojo.addOnLoad(getResults);
</script>
In my form I simply do:
<ft:form-template onsubmit="getReseults()" method="post"ajax="true">
</ft:form-template>
Nothing happens! The form submits ok, but I am not getting a message back
saying "Your details are being processed. Please wait". Any ideas?
regards

Sorry the code should have read:
function testForm() {
dojo.addOnLoad(function() {
dojo.require("cocoon.ajax.BUHandler");
dojo.event.connect(cocoon.ajax.BUHandler.prototype, "processResponse",
function() {
alert("Page has been updated!")
})
});
}

Re: form-template onSubmit issue
Posted by Andrew Madu <an...@gmail.com>.
Hi Simone,
in fact I would appreciate some help with this if possible. I have
implemented ajax=true in my form and upadated my sitemap to take account of
ajax process calls. The problem I am having now is the in the implementation
of the javascript. OnSumit I call a function and do away with
forms_onsubmit(); which is defined in forms-field-styling.xsl right? Now my
code is as follows:
function testForm() {
dojo.require("cocoon.ajax.BUHandler");
dojo.event.connect(cocoon.ajax.BUHandler.prototype,"processResponse",
function() {alert("Page has been updated!")}
}
dojo.addOnLoad(testForm());
But when I try to subit the form, onSubmit("testForm") nothing happens, the
form does not submit! What am I not doing right here?
regards
Andrew

Simone,
many thanks for your suggestions, I found them very helpful. For the anyone
interested the mail Simone makes mention of in regards to intercepting Ajax
call with dojo can be found here:

Re: form-template onSubmit issue
Posted by Simone Gianni <s....@thebug.it>.
Hi Andrew,
validation is carried server side, not client side, so there is no way
to give a client side feedback when the form validated correctly, since
that information (the fact that the validation was ok) is on the server.
The possible approaches for this kind of situations are the following :
- Ajax=false : Show something at client side *always* when the form is
submitted, like "Your form is being processed", if the form has some
validation errors the page will be reloaded with validation errors
inside, otherwise the rest of the flow will go on as expected while the
user is looking at the javascript thing, until a new page arrives. This
can be done quite simply attaching a client side onSubmit event to the form.
- Ajax=true : The same tecnique with ajax = true is still valid, but you
have to intercept the ajax call instead of the form submit/page
reloading. There is a mail in dev, written by Sylvain Wallez answering
me, on how to intercept ajax calls with dojo AOP .. the mail was about
doing test with selenium, but the concept is the same.
- Both ajax=true and false : if the user has to wait because the flow is
going to do a lot of work (like, retrieve tons of stuff from a database
etc..) then the solution is a bit more complex, since the HTTP protocol
does not have a push system, cocoon flow cannot do a
sendPage("waitplease"), then do other stuff, then another
sendPage("results"). So the trick could be :
... set a session attribute acting as a semaphore
... do a sendPage("waitplease")
... the wait please page will use a javascript timer to "poll" the
session attribute every 5 seconds or so
... while it's still true the same page will be redisplayed, otherwise
the next continuation will be called.
... the flow, after the sendPage("waitplease") will do all the long
running stuff
... at the end will clear the session attribute
The last solution is quite complicated, but will achieve what you need.
Hope this helps,
Simone

Re: form-template onSubmit issue
Posted by Andrew Madu <an...@gmail.com>.
Ok guys,
this is really bugging! me now. In a nutshell here is what I want to do:
1. on submitting a form (cform with fd:javascript validation) which has been
validated correctly, show a message to the user that the form is being
processed. The form in question is a credit card validation page which when
validated calls a paypal api which checks the credit card details and
returns various values based upon whether the check was successful or not.
All of that works fine! What I can't get my head around at the moment is how
to send a message to the user stating that their details are being
processed, as the the process can take around 9-15 seconds to process,
although paypal say anywhere upwards of 30 seconds is possible. So rather
than having a user sitting at a page which looks like it is doing nothing,
it would be nice to display a message saying something is happening.
I thought of setting a session variable in the fd:javascript section only
when a return type of true is reported and then in my jk file doing
something like:
<jx:if test="${cocoon.session.getAttribute('processingDetails')
== true}">
<tr>
<td colspan="2">Your details are being
processing......</td>
</tr>
</jx:if>
but of course once the form has been valaidated as true the page is not
re-written again so that code will never be displayed. Only if the
validation failed would it be displayed. So, how to return a message to a
user once a cform with required fields has been successfully validated? Any
ideas?
regards
Andrew

I am not quite sure am I answer your question or not...I had done the
similar work, but I didn't touch resources/forms-lib.js and resources/forms-
field-styling.xsl those kind of files.
when click submit button, call a java script to validate the input, I use
the regular expression for validation, which is very powerful.
and if the validation checking is successful, then continue, otherwise give
a alert.

AW: form-template onSubmit issue
Posted by Christofer Dutz <du...@c-ware.de>.
Hi Andrew
I didn't have a closer look at the forms-lib stuff and after looking again I
could see, that I mixed fd:javacript and actions with included javascript .
should have had that big cup of coffe before writing mails ;)
Regards,
Chris

Hi Christofer,
I think you will find that the javascript in resources/forms-lib.js is very
much client side. Either that or the cocoon developers have devised a way to
make statements like document.body.appendChild(element) work server-side!
;-)
Any ideas anyone?
regards

Hi Andrew
How about some print-statements?
As far as I know the java-script is executed server-side, so an alert will
not work. If you do a "print(case)" this should output to your console the
value of case.

Betreff: ft:form-template onSubmit issue
Hi,
I have a cform which has javascript validation on some form fields
(widgets):
<fd:javascript>
if (case) {
return true;
} else {
return false;
}
</fd:javascript>
<fd:widgets>
</fd:widgets>
Basically what I want to happen is that when <form> is returned a value of
'true' to indicate that all form fields have been validated successfully a
javascript function is carried out, for example an alert is triggered
alert("success").
I have edited both resources/forms-lib.js and
resources/forms-field-styling.xsl and absolutely nothing is happening.
Firstly how can I determine in javascript whether true has been returned to
the form after it has been submitted? I have tried a check on
document.Form.submitted and had no joy with that. Any ideas?
regards
Andrew

Hi Andrew
How about some print-statements?
As far as I know the java-script is executed server-side, so an alert will
not work. If you do a "print(case)" this should output to your console the
value of case.

Christofer
