程式碼範例
以下是應用範例。
範例 1
在下列範例中，系統會將同一個字串當做輸入字串和 cutset 傳遞，因此會產生空字串。
strings.trim("str", "str") // ""
範例 2
在下列範例中，系統會將空字串當做 cutset 傳遞，因此會產生原始字串 str，因為 cutset 中未指定要移除的字元。
strings.trim("str", "") = "str"
範例 3
在下列範例中，函式會產生空字串，因為輸入字串已為空白，且沒有要移除的字元。
strings.trim("", "str") = ""
範例 4
在下列範例中，函式會產生 str，因為 trim 函式會移除下列項目：
- 「a aastraa aa 」中的尾端空白字元
- cutset 中指定的字元 (空格、a)
strings.trim("a aastraa aa ", " a") = "str"
