我试图通过rdflib.js检索联系人列表。它正确加载并将其保存在范围内的列表中。
它确实识别列表中的项目数,但我无法呈现值,因为$ scope没有更新,似乎我在错误的位置调用$ scope.apply()。这似乎是因为我把它称为有角度的,但我故意在角度上下文(nowOrWhenFetched)之外的函数内调用它,所以对我来说没有意义。有什么帮助吗?
$scope.load = function () {
//$scope.getContactsList();
var g = $rdf.graph();
var f = $rdf.fetcher(g);
f.nowOrWhenFetched($scope.path + '*',undefined,function(){
var DC = $rdf.Namespace('http://purl.org/dc/elements/1.1/');
var RDF = $rdf.Namespace('http://www.w3.org/1999/02/22-rdf-syntax-ns#');
var LDP = $rdf.Namespace('http://www.w3.org/ns/ldp#');
//var myOntology = $rdf.Namespace('http://user.pds.org/ontology/');
var VCARD = $rdf.Namespace('http://www.w3.org/2006/vcard/ns#');
var evs = g.statementsMatching(undefined, RDF('type'), VCARD('Individual'));
if (evs != undefined) {
for (var e in evs) {
var id = evs[e]['subject']['value'];
var fullname = g.anyStatementMatching(evs[e]['subject'], VCARD('fn'))['object']['value'];
var email = g.anyStatementMatching(evs[e]['subject'], VCARD('hasEmail'))['object']['value'];
var phone = g.anyStatementMatching(evs[e]['subject'], VCARD('hasTelephone'))['object']['value'];
var contact = {
id: id.slice(id.length-1),
Name: fullname,
Email: email,
Phone: phone
};
$scope.contacts.push(contact);
}
}
$scope.apply();
});
};
感谢。
