另一种解决方案是分别使用 Javascript 和 jQuery:
(function($) { $(document).ready(function() {
// A Dexterity-based document is added:
if( window.location.href.endsWith('/++add++Document') ) {
// Grab the parent's title of the current title-tag's content:
var title = $('title')[0].innerHTML.split(' — ')[0]
// Prefill the new document's title-field with the parent's title:
$('#form-widgets-IDublinCore-title').val(title)
}
// An Archetypes-based document is added:
if( window.location.href.indexOf('/portal_factory/Document/') > -1 ) {
var parentUrl= document.referrer
var parentTitleEleId = 'parent-fieldname-title'
// Provide ele to load parent's title into:
var loadEle = document.createElement('span')
// Load parent's title into ele:
$(loadEle).load(parentUrl + ' #' + parentTitleEleId, function() {
// After loading finished, fetch parent-title of ele, remove
// trailing spaces and set it into the new doc's title-field:
$('#title').val(loadEle.childNodes[0].innerHTML.trim())
// Thy had served y'er purpose, vanish:
loadEle.remove()
});
}
});})(jQuery);

您可以对行为进行monkeypatch或子类化Basic metadata
以修改_get_title的行为:https ://github.com/plone/plone.app.dexterity/blob/master/plone/app/dexterity/behaviors/metadata.py#L350-L351
