(validate) Customising bassistance validation plugin

[Iwan Vosloo-2]

Hello,

We are trying to use the validation plugin with HTML that's been
generated for us.  There are a couple of things we'd like to customise
if we can for the plugin to work with this HTML.

One of them is that the code uses some HTML5 conventions - like how to
specify when an input is required:

Usually you'll have something like:
<input type="text" class="required">

In our HTML, we'd have:
<input type="text" required>

Is there a way to customise/configure the validation plugin to
recognise the latter?

Thanks
- Iwan

The plugin by default picks up attributes, so if you're using attribute names that match validation plugin methods, it should work like that. Though you may need to also provide a value, ala required="true", not sure about that.

This works for validation methods, but not for the required...

Ah,

I got it working... The value of the "required" attribute should be a
dependency-expression (http://docs.jquery.com/Plugins/Validation/
Methods/required#dependency-expression  )

So, required="true" does not work.  I'm still trying to figure out
what else can be in there / what exactly a dependency-expression is,
but it seems that the following works (although I'd like to understand
still...):

required=":true"
required="{:true}"
required="{anynamehere:true}"
required="{:anystringhere}"

Of course, its a jquery expression, what else...

However, I do think the docs may be wrong:  at
http://docs.jquery.com/Plugins/Validation/Methods/required#dependency-expression

In the arguments section it reads:
"An expression (String) is evaluated in the context of the element's
form, making the field required only if the expression returns more
than one element."

Surely that should be "one or more elements"?
