---|
String.replace(regex, replacement, flags) | 字串 |
引數 | 類型 | 詳細資料 |
---|
這個:input | 字串 | 要搜尋的字串。 |
regex | 字串 | 要比對的規則運算式。 |
replacement | 字串 | 取代相符子字串的字串。 |
flags | 字串,預設值為「""」 | 字串,用於指定規則運算式旗標的組合,具體來說,就是一或多個下列旗標:「g」(全域比對) 或「i」(忽略大小寫) |
範例
程式碼編輯器 (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
