FileSystemObject 示例代碼 · javascript詳解

| JScript? | [語言參考](#) | |-----|-----| # FileSystemObject 示例代碼在本節描述的示例代碼，提供真實的例子來示范在 **FileSystemObject** 對象模式中可用的許多功能。該代碼顯示了如何一起使用對象模式的所有功能，以及如何在您自己的代碼中有效地使用這些功能。請注意，由于該代碼是極一般的，所以要使該代碼能夠真正在您的機器上運行，可能需要一些其他代碼和小小的變更。這些改變之所以必要，是因為在 Active Server Pages 和 Windows Scripting Host 之間，為輸入和輸出給用戶采用了不同的方法。要在 Active Server Pages 上運行該代碼，則采取以下步驟：創建一個標準的 Web 頁，后綴名為 .asp。把下面的示例代碼復制到 &ltBODY>...</BODY> 標記之間的文件中。把所有代碼包裝器到 <%...%> 標記內。把 **Option Explicit** 語句從當前位置移動到 HTML 頁的最頂部，甚至在 <HTML> 開始標記前。把 <%...%> 標記放置在 **Option Explicit** 語句周圍，以保證它在服務器端運行。把下面的代碼添加到示例代碼末尾： ~~~ Sub Print(x) ~~~ ??? ~~~ Response.Write "<PRE>&ltFONT FACE="" ~~~ 宋體 ~~~ "" SIZE=""1"">" ~~~ ~~~ ???Response.Write x ~~~ ~~~ ???Response.Write "</FONT></PRE>" ~~~ ~~~ End Sub ~~~ ~~~ Main ~~~ 前面的代碼增加一個將在服務器端運行，但在客戶端顯示結果的打印過程。要在 Windows Scripting Host 上運行該代碼，則把下面的代碼添加到示例代碼的末尾： ~~~ Sub Print(x) ~~~ ??? ~~~ WScript.Echo x ~~~ ~~~ End Sub ~~~ ~~~ Main ~~~ 下面就是示例代碼： ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ' FileSystemObject ~~~ 示例代碼 ~~~ 'Copyright 1998 Microsoft Corporation ~~~ 。???保留所有權利。 ~~~ ~~~ ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ Option Explicit ~~~ ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ ' ~~~ 對于代碼質量： ~~~ ' 1) ~~~ 下面的代碼有許多字符串操作，用 ~~~ "&" ~~~ 運算符來把短字符串連接在一起。由于 ~~~ ' ~~~ 字符串連接是費時的，所以這是一種低效率的寫代碼方法。無論如何，它是 ~~~ ' ~~~ 一種非常好維護的寫代碼方法，并且在這兒使用了這種方法，因為該程序執行 ~~~ ' ~~~ 大量的磁盤操作，而磁盤操作比連接字符串所需的內存操作要慢得多。 ~~~ ' ~~~ 記住這是示范代碼，而不是產品代碼。 ~~~ ' ~~~ ~~~ ' 2) ~~~ 使用了 ~~~ "Option Explicit" ~~~ ，因為訪問聲明過的變量，比訪問未聲明的變量要 ~~~ ' ~~~ 稍微快一些。它還能阻止在代碼中發生錯誤，例如，把 ~~~ DriveTypeCDROM ~~~ 誤拼 ~~~ ' ~~~ 成了 ~~~ DriveTypeCDORM ~~~ 。 ~~~ ' ~~~ ~~~ ' 3) ~~~ 為了使代碼更可讀，該代碼中沒有錯誤處理。雖然采取了防范措施，來保證代碼 ~~~ ' ~~~ 在普通情況下沒有錯誤，但文件系統是不可預知的。在產品代碼中，使用 ~~~ ' On Error Resume Next ~~~ 和 ~~~ Err ~~~ 對象來捕獲可能發生的錯誤。 ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ ' ~~~ 一些容易取得的全局變量 ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ Dim TabStop ~~~ ~~~ Dim NewLine ~~~ ~~~ Const TestDrive = "C" ~~~ ~~~ Const TestFilePath = "C:\Test" ~~~ ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ ' ~~~ 由 ~~~ Drive.DriveType ~~~ 返回的常數 ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ Const DriveTypeRemovable = 1 ~~~ ~~~ Const DriveTypeFixed = 2 ~~~ ~~~ Const DriveTypeNetwork = 3 ~~~ ~~~ Const DriveTypeCDROM = 4 ~~~ ~~~ Const DriveTypeRAMDisk = 5 ~~~ ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ ' ~~~ 由 ~~~ File.Attributes ~~~ 返回的常數 ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ Const FileAttrNormal = 0 ~~~ ~~~ Const FileAttrReadOnly = 1 ~~~ ~~~ Const FileAttrHidden = 2 ~~~ ~~~ Const FileAttrSystem = 4 ~~~ ~~~ Const FileAttrVolume = 8 ~~~ ~~~ Const FileAttrDirectory = 16 ~~~ ~~~ Const FileAttrArchive = 32 ~~~ ~~~ Const FileAttrAlias = 64 ~~~ ~~~ Const FileAttrCompressed = 128 ~~~ ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ ' ~~~ 用來打開文件的常數 ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ Const OpenFileForReading = 1 ~~~ ~~~ Const OpenFileForWriting = 2 ~~~ ~~~ Const OpenFileForAppending = 8 ~~~ ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ ' ShowDriveType ~~~ ~~~ ' ~~~ 目的： ~~~ ~~~ ~~~ ' ~~~ 生成一個字符串，來描述給定 ~~~ Drive ~~~ 對象的驅動器類型。 ~~~ ' ~~~ 示范下面的內容 ~~~ ' - Drive.DriveType ~~~ ~~~ '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ~~~ ~~~ Function ShowDriveType(Drive) ~~~ ???
