  1. ASP基礎-VBScript常用函數 張森

  2. CStr : 轉換為字串 • CStr(10)+CStr(20)  1020 • CInt : 轉換為整數 • A=“10” CInt(A)+20  30 • 其他型別轉換函數 • CBool, CByte, CCur, CDate, CDbl, CLng, CSng

  3. Int : 取小於或等於某數的最大整數 • Int(25.7)  25 • Int(-33.6)  -34 • Fix : 去掉小數部分 • Fix(25.7)  25 • Fix(-33.6)  -33

  4. InStr : 尋找字串 • X=“This is a book.” A=InStr(X, “is”)  3 (從X第1個字元起找出“is”出現的位置) A=InStr(4, X, “is”)  6 (從X第4個字元起找出“is”出現的位置)

  5. Join : 將字串陣列組合成一個字串 • Dim A(2) A(0)=“I” A(1)=“am” A(2)=“God.” Join(A)  “I am God.” Join(A, “,”)  “I,am,God.”

  6. Split : 將字串分割成字串陣列 • X=“男 女” Y=“男, 女” A=Split(X)  A(0)=“男”A(1)=“女” B=Split(Y, “, ”)  B(0)=“男”B(1)=“女”

  7. Len : 計算字串長度 • Len(“Windows Me 中文版”)  14 (中文、空白皆算一個字元) • Left, Right : 傳回左/右邊的字元 • A=“Windows Me 中文版” Left(A,3)  “Win” Right(A,3)  “中文版”

  8. Mid : 取中間字元 • A=“Windows Me 中文版” Mid(A,9)  “Me 中文版” Mid(A,9,2)  “Me” • LTrim, RTrim, Trim : 去掉空白字元 • A=“ ASP ” LTrim(A)  “ASP ” RTrim(A)  “ ASP” Trim(A)  “ASP”

  9. Replace : 取代字串 • A=“Windows Me 中文版” Replace(A, “Me”, “98”)  “Windows 98 中文版” • UCase, LCase : 轉換為大/小寫 • A=“Windows Me 中文版” UCase(A)  “WINDOWS ME 中文版” LCase(A)  “windows me 中文版”

  10. Date, Time, Now : 系統的日期,時間 • Year, Month, Day : 取出年,月,日 • Year(Date), Month(Date), Day(Date) • Hour, Minute, Second : 取出時,分,秒 • Hour(Time), Minute(Time), Second(Time)
