VBScript 中的连接运算符
VBScript 支持以下连接运算符 −
假设变量 A 为 5,变量 B 为 10 −
运算符 | 描述 | 示例 |
---|---|---|
+ | 添加两个值,因为变量值为数字 | A + B 将给出 15 |
& | Concatenates two Values | A & B 将给出 510 |
示例
尝试以下示例来了解 VBScript 中可用的连接运算符 −
<!DOCTYPE html> <html> <body> <script language = "vbscript" type = "text/vbscript"> Dim a : a = 5 Dim b : b = 10 Dim c c = a+b Document.write ("Concatenated value:1 is " &c) 'Numeric addition Document.write ("<br></br>") 'Inserting a Line Break for readability c = a&b Document.write ("Concatenated value:2 is " &c) 'Concatenate two numbers Document.write ("<br></br>") 'Inserting a Line Break for readability </script> </body> </html>
当您将其另存为 .html 并在 Internet Explorer 中执行时,上述脚本将产生以下结果 −
Concatenated value:1 is 15 Concatenated value:2 is 510
连接也可用于连接两个字符串。 假设变量 A="Microsoft",变量 B="VBScript",则 −
运算符 | 描述 | 示例 |
---|---|---|
+ | 连接两个值 | A + B 将给出 MicrosoftVBScript |
& | 连接两个值 | A & B 将给出 MicrosoftVBScript |
示例
尝试以下示例来了解 VBScript 中可用的连接运算符 −
<!DOCTYPE html> <html> <body> <script language = "vbscript" type = "text/vbscript"> Dim a : a = "Microsoft" Dim b : b = "VBScript" Dim c c = a+b Document.write ("Concatenated value:1 is " &c) 'Numeric addition Document.write ("<br></br>") 'Inserting a Line Break for readability c = a&b Document.write ("Concatenated value:2 is " &c) 'Concatenate two numbers Document.write ("<br></br>") 'Inserting a Line Break for readability </script> </body> </html>
当您将其另存为 .html 并在 Internet Explorer 中执行时,上述脚本将产生以下结果 −
Concatenated value:1 is MicrosoftVBScript Concatenated value:2 is MicrosoftVBScript
