jQuery Placeholder

Integrates jQuery Watermark for z3c.form on Plone by

1. registering jquery.watermark's JavaScript and CSS
2. introducing ''placeholder''-directive to be used in schemas
3. registering value adapter to for annotated placeholder value
4. registering custom JavaScript to initialize watermarks

I wonder, if this product should've been named ''formwidget''-something...

Example of Use

from zope import schema

from plone.directives import form

from jyu.z3cform.placeholder.directives import placeholder

from zope.i18nmessageid import MessageFactory as ZopeMessageFactory
_ = ZopeMessageFactory("my.domain")

class MyForm(form.Schema):
    """An example form
    """
    placeholder(subject=_u("Type something here.."))
    subject = schema.TextLine(
      title=_(u"Subject"),
      description=_("Subject of this submission"),
      required=True,
      )

Overlay Support

When you register custom form overlays in your custom JavaScript, you'd like to include placeholder support in your JavaScript like:

$(document).ready(function() {
  $($('#my-form-link').prepOverlay({
    subtype: 'ajax',
    cssclass: 'content',
    formSelector: 'form',
    width: '40em',
  }).attr("rel")).bind("onLoad", function() {
    $(this).find("form .field").placeholder_z3cform();
  });
});
