You will have to store this as a JSON-encoded string since the
persistence store can only contain string values. The gadgets.util
library includes functions for encoding a JavaScript data structure as
a string and parsing this string back into the JavaScript object:
// Convert to JSON string:
var myArray = ['value1', 'value2', 'value3'];
var jsonString = gadgets.json.stringify(myArray);
// Convert from JSON string:
var myArrayReloaded = gadgets.json.parse(jsonString);
myArrayReload.push('value4');
Here is the API reference page:
