I'ld like to save variables to an Encrypted Local Store. This example is working but how can I extend it to开发者_C百科 save more than 1 variable?
// To save variable to ELS (EncryptedLocalStore)
function saveItems() {
var m1:String = "my item 1";
// HOW TO ADD THESE?:
// var m2:String = "my item 2";
// var m3:String = "my item 3";
// var m4:String = "my item 4";
//
var bytes:ByteArray = new ByteArray();
bytes.writeUTFBytes(m1);
EncryptedLocalStore.setItem("item1", bytes);
}
// Read it from ELS
function getItems() {
var storedValue:ByteArray = EncryptedLocalStore.getItem("item1");
//
trace(storedValue.readUTFBytes(storedValue.length));
}
Thanks.
Rinse and repeat what you already have, and avoid duplicate code by moving common functionality into their own methods:
private function saveItems():void {
var m1:String = "my item 1";
var m2:String = "my item 2";
var m3:String = "my item 3";
var m4:String = "my item 4";
saveItem("item1", m1);
saveItem("item2", m2);
saveItem("item3", m3);
saveItem("item4", m4);
}
private function saveItem(key:String, value:String):void
{
var bytes:ByteArray = new ByteArray();
bytes.writeUTFBytes(value);
EncryptedLocalStore.setItem(key, bytes);
}
