我在另一个没有找到任何答案的论坛上发现了这个问题。我认为这是一个很好的问题，值得在这里提出。我在这里逐字粘贴。

Hi guys, I've got a pie in the sky
idea, and I'm just wondering if it's
even remotely possible, or if I should
give up and try something else.

I've got a bunch of Zend_Dojo_Form
forms with a bunch of custom
validators on the Zend side - they
work fine, the form errors out when
values are incorrect, it's all working
exactly as you'd expect, however, what
I'd also like is for the same
validators to work on the Dojo client
side of the form - but without having
to completely re-implement them,
validator by validator.

I understand that at its simplest
level, the Dojo isValid method doesn't
know or care about the application
behind it, and indeed for it to even
be able to get access to the errors in
the application it'd have to attempt a
submit, which isn't what it's meant to
do, but has anyone tried a system of
something like:

override form onSubmit to add our code

test Dojo isValid()

if the Dojo side is happy, AJAX submit the form

if successful, which would be returned i don't know how, then
forward on to the appropriate page

if not successful, then (and this is where it gets tricky I guess) pass
back enough data to know what field
errored out, what the error was, and
then call enough of the Dojo isValid
internal guts to make the form look
like it didn't validate?

Sorry to just be airing ideas like
this, I just figured it might be
really useful if we could come up with
a way to sort of globally add custom
validators to our forms that work both
client and server side, without having
to implement them uniquely on both
sides.

Meh，dojo：(

使用Jquery：)

看看这真棒：

Ajaxify您的Zend_Form验证

We’re going to take what was put
together in the last 3 videos and now
include some server-side validation
that will appear asynchronously. This
is an example of using Zend_Form as a
validation tool via JSON.

Zend_Form有一个processAjax()方法，可用于验证任何或所有表单元素，并返回JSON编码的结果(真或错误列表)。

因此，它可以用于在onsubmit事件处理程序中对表单的全部或部分进行预验证；甚至是在其onchange事件处理程序中单独预先验证字段。
