範例
程式碼編輯器 (JavaScript)
// A dictionary (e.g. results of ee.Image.reduceRegion of an S2 image).
var dict = ee.Dictionary({
B1: 182,
B2: 219,
B3: 443
});
print('Values for selected keys converted to ee.List',
dict.values(['B1', 'B2']));
print('Values for all keys converted to ee.List', dict.values());
