VBA連接操作
下表列出了所有的VBScript語言支持的連接操作。假設變量A=5和變量B=10,則:
操作符
描述
例子
+
相加兩個變量值的數值
A + B = 15
&
連接兩個值
A & B = 510
示例
試試下面的例子就明白了在 VBScript 的連接運算符:
Private Sub Constant_demo_Click() Dim a as Integer : a = 5 Dim b as Integer : b = 10 Dim c as Integer c=a+b
msgbox ("Concatenated value:1 is " &c) 'Numeric addition
c=a&b
msgbox ("Concatenated value:2 is " &c) 'Concatenate two numbers End Sub
試試下面的例子就明白了所有VBA中可用的邏輯運算符,創建一個按鈕,並添加以下函數:
Concatenated value:1 is 15
Concatenated value:2 is 510
串聯,也可以用於連接兩個字符串。假設變量A="Microsoft"和變量B =「VBScript」,則:
操作符
描述
例子
+
連接兩個值
A + B = MicrosoftVBScript
&
連接兩個值
A & B = MicrosoftVBScript
示例
試試下面的例子就明白了所有VBA中可用的邏輯運算符,創建一個按鈕,並添加以下函數:
Private Sub Constant_demo_Click() Dim a as String : a = "Microsoft" Dim b as String : b = "VBScript" Dim c as String c=a+b
msgbox("Concatenated value:1 is " &c) 'addition of two Strings
c=a&b
msgbox("Concatenated value:2 is " &c) 'Concatenate two String End Sub
將它保存爲 html 和Internet Explorer打開它,那麼上面的腳本會產生以下結果:
Concatenated value:1 is MicrosoftVBScript
Concatenated value:2 is MicrosoftVBScript
