Aufgrund der in letzter Zeit langsamen Internetgeschwindigkeit kann die Webseite beim Überprüfen der Aktieninformationen immer nicht geöffnet werden. Ich habe in letzter Zeit Ajax studiert, also habe ich JQuery verwendet, um eine Seite zu erstellen, die automatisch Echtzeitdaten zu Sina-Aktien liest
Sinas Finanzkanal war immer sehr gut gemacht. Aufgrund der in letzter Zeit langsamen Internetgeschwindigkeit kann die Webseite jedoch nicht geöffnet werden, wenn die Aktieninformationen überprüft werden. Ich habe in letzter Zeit Ajax studiert und daher mit JQuery eine Seite erstellt, die automatisch Echtzeitdaten der Sina-Aktie liest.
