示例
代码编辑器 (JavaScript)
print(ee.String('abc-abc').replace('abc', 'X')); // X-abc
print(ee.String('abc-abc').replace('abc', 'X', 'g')); // X-X
print(ee.String('abc-abc').replace('abc', '', 'g')); // -
print(ee.String('aBc-Abc').replace('abc', 'Z', 'i')); // Z-Abc
print(ee.String('aBc-Abc').replace('abc', 'Z', 'ig')); // Z-Z

import ee
import geemap.core as geemap
Colab (Python)
print(ee.String('abc-abc').replace('abc', 'X').getInfo()) # X-abc
print(ee.String('abc-abc').replace('abc', 'X', 'g').getInfo()) # X-X
print(ee.String('abc-abc').replace('abc', '', 'g').getInfo()) # -
print(ee.String('aBc-Abc').replace('abc', 'Z', 'i').getInfo()) # Z-Abc
print(ee.String('aBc-Abc').replace('abc', 'Z', 'ig').getInfo()) # Z-Z
