Ich habe ein Datum im Format von:
2010-11-30T08:32:22+0000
2010-11-27T20:59:17+0000
aus einem Feed, im String-Format zu Javascript, jetzt möchte ich es in ein Date-Objekt konvertieren. Wie kann ich es in javascript tun?

Ich fand Fall wie Date.fromISOString('2011-06-01T00:00:00Z') erstellt Datum, das durch Zeitzone versetzt ist, so dass dies nur korrekt funktioniert, wenn Ihr Computer in GMT ist. Hier ist die Änderung, die ich gemacht habe, um das zu beheben.
Um ein korrektes Datum aus einer beliebigen ISO-Zeichenkette zu erhalten, müssen Sie die lokale Zeitzone anpassen, auch wenn der angegebene Eintrag GMT ist.
Hier ist ein funktionierendes Beispiel, das Sie als .html-Datei speichern und auf Ihrem Computer testen können:
