Creare un esempio di LocalStorage. Quando utilizzo il browser web Chrome, funziona perfettamente. Ma quando provo su iPhone Emulator, non funziona. Per favore aiuto. Ecco il mio codice per impostare il valore di archiviazione locale:LocalStorage non funziona su PhoneGap
function onclick(){
window.localStorage.setItem("data","Nguyen Minh Binh");
}

Ecco il codice in cui ho cercato di ottenere i dati salvati:

EDIT: A Whizkid747 di suggerire, a cambiare la sorgente di script come di seguito, ma ancora non funziona.

</html>
EDIT2: Prova a impostare localStorage a OnDeviceReady poi ottenerlo righe successive, ma ancora non funziona.

<script type="text/javascript" charset="utf-8">
// Wait for PhoneGap to load
//
document.addEventListener("deviceready", onDeviceReady, false);
// PhoneGap is ready
//
function onDeviceReady() {
window.localStorage.setItem("key", "minhbinh");
var keyname = window.localStorage.key(i);
// keyname is now equal to "key"
var value = window.localStorage.getItem("key");
// value is now equal to "value"
window.localStorage.removeItem("key");
window.localStorage.clear();
// localStorage is now empty
$("p#p1").text(value);
}
</script>

Si prega di vedere la mia modifica. Ho cambiato i codici come suggerimento, ma non funziona. –
Vedo che stai cercando di recuperare i dati dalla memoria locale prima di impostarli. Puoi impostare i dati nell'evento deviceReady e poi prenderlo nella riga successiva? – Whizkid747
Si prega di consultare il mio edit2. Ho impostato localstorage su onDeviceReady e ho ottenuto la riga successiva, non funziona ancora. –
