Aug 06, 2025 am 09:55 AM使用std::ifstream通過嘗試打開文件並檢查流狀態(tài)來判斷文件是否存在,但同時驗(yàn)證了可讀性;2.C 17及以上推薦使用std::filesystem::exists,它直接檢查文件是否存在且更高效;3.若需區(qū)分不存在與其他錯誤,可使用std::filesystem::status配合error_code避免異常;應(yīng)優(yōu)先選擇符合C 版本且滿足需求的方法,C 17中使用std::filesystem::exists是最佳實(shí)踐。
Aug 06, 2025 am 09:54 AM要禁用HTML5元素,使用disabled屬性,該屬性適用於表單元素如、、、和;1.添加disabled屬性即可禁用元素,無需賦值;2.禁用元素默認(rèn)呈現(xiàn)灰色外觀,可通過:disabled偽類自定義樣式;3.禁用的表單元素不會隨表單提交;4.可通過JavaScript動態(tài)設(shè)置disabled屬性值來切換狀態(tài);5.非表單元素不支持disabled屬性,需結(jié)合CSS的pointer-events:none和JavaScript模擬禁用效果。
