vbs脚本：vbs脚本语言

本文主要介绍关于脚本语言,Vbscript的知识点，对【vbs脚本】和【vbs脚本语言】有兴趣的朋友可以看下由【Princesk】投稿的技术文章，希望该技术和经验能帮到你解决你所遇的【脚本】相关技术问题。

vbs脚本语言

1、注释

两种格式REM +内容或者’+内容

'REM 这是注释
' Dim name:name = 2
' const name2=33
' Dim msg
' '这也是注释
' 'nskdjkasj
' msg="shu"

vbs内建函数。inputbox表示输入。msgbox表示输出
vbs的函数为一个黑盒，只需要关注输出和输入结果即可

2、参数类型

vbs与其他与语言一样，分为常量和普通变量，常量由const定义，变量由Dim声明，这两个声明方式不一样。

const name4=33
const name6 =2
Dim name5:name5 = 2
Dim name3,nam23
name3=23

声明的变量只有一种类型variant，下辖多个子类型，根据上下文判断是数字还是字符串，数字可以进行加减乘数 取余运算

变量子类型

’ 'Empty - 未初始化都是这个值，数值变量，值为0，字符串为""
’ 'Null - 无任何数据的var
’ 'Boolean - true或者false
’ 'Byte - 包含0到255的整数
’ 'Integer - -32768到32768
’ 'Currency - -922337203685477.5808 到 922337203685477.5808
’ 'Long - -2147483648 到 2147483648
’ 'Single - 单精度浮点数，-3402823E38 到 -1.401298E-45（负数），1.401298E-45 到 3402823E38（整数）
’ 'Double - 双精度浮点数，-1.79769313486232E308 到 -4.94065645841247E-324（负数）
’ 'Date(Time) - 公元100年1月1人到公元9999年12月31日
’ 'String - 可变长字符串，最大长度20亿个字符
’ 'Object - 包含对象
’ 'Error - 包含错误号

’ '基本每个子类型都有对应的vbs函数进行转换
’ 'Cbool - 换成布尔型
’ 'Cbyte - 转成0到255的整数
’ 'Ccure, Cdbl, Csng - 转成浮点小数，前面那个小数点4位，后面2个更大
’ 'Cdate - 转换成日期值
’ 'Cint,Clng - 转成整数，后者范围比前者大
’ 'Cstr - 转成字符串

3、选择语句if和select case

vbs脚本if 语句 if语句采用=而不是==号判断是否相等

'选择语句if

Dim a , d
 a=2
 d=3
if a>d Then
    msgbox a
else
  msgbox d
End if

Dim kl
kl = inputbox("putin kl")
select case kl
case 23
 msgbox("ss")
case 2
 msgbox "2"
case end
 msgbox 56
end select

4、循环语句 do…loop

'do …loop 跳出循环采用exit do

const pass =“123456”

do 
    a=inputbox("putin")
    if a=pass then
        exit do
        end if
    
loop

dim i:i=1
do 
        a=a=inputbox("putin")
        if a=pass then
            exit do
                else
                i = i + 1
            end if

            if i = 4 then
                exit do
                end if
loop

do while …loop

dim i :i = 1
do while i <4
a=a=inputbox("putin")
 if a=pass then
 exit do
 else
 i = i + 1
 end if
 loop

while 放在loop后面减少一次循环
 dim i:i=1
 do 
  a=inputbox("putin")
  if a=pass then
     exit do
  else
     i = i + 1
  end if
 loop while i <4

for 循环语句

REm for 循环次数 ...... next，

 dim kp
 for kp=0 to 5
 msgbox k 
next

while…wend 6、数组，一维数组和二维数组

 dim a(9)
 for i =0 to 9
 a(i) = i
 msgbox a(i)
 next
dim name(8),str

for i = 0 to 8
'这里&符号是合并字符串的意思
name(i) = inputbox("putin your number"&i+1)
next
for i = 0 to 8
msgbox name(i)
i=i+1

'这里只会打印1,3,5,7,9，因为每次循环多进行了一次i的计算
next

5、函数 vbs自带函数

vbs常用函数

http://www.zzvips.com/article/90104.html

vbs自定义函数

两种sub和function

sub没有返回值，function可以选择带有返回值，在自身的functio定义返回值，格式为函数名称=返回值

   Function reboot()
        xsh.Screen.SynchrOnous= true
	    xsh.Screen.Send("reboot")
        xsh.Screen.Send(VbCr)
		xsh.Session.Sleep(100000)
        xsh.Screen.Send(VbCr)
   End function  
   

   Function login()
        xsh.Screen.Send(VbCr)
		xsh.Screen.WaitForString("login")
		xsh.Screen.Send(VbCr)
		xsh.Screen.Send("root")
		xsh.Screen.Send(VbCr)
		xsh.Session.Sleep(3000)
		xsh.Screen.Send(VbCr)
   End function   
    
   function check(kj )
    xsh.Screen.Send(" route  -ne | grep cellular1 | wc -l ")
		xsh.Screen.Send(VbCr)
        screenrow = xsh.Screen.CurrentRow
        data = xsh.Screen.Get(screenrow-1,1,screenrow-1,20)
		
		if CInt(Instr(1,data,"4",1)) = "1"  Then
            check(kj) = -1
		else 
		    check(kj) = kj
        End If
   End function
   
   
   Function error(count0 ,j0)
           xsh.Screen.Send("check_error cellular1_offline vbs_will_stop:"+CStr(count0))
		   xsh.Screen.Send(VbCr)
           xsh.Dialog.MsgBox("check_error cellular1 offline vbs_stop: reboot:"+Cstr(count0))
           xsh.Dialog.MsgBox("check route"+Cstr(j0))
   End Function
   
Sub Main
   Dim count:count = 1
   do while count<3
		 call login()
		 dim j:j=1
		 do while j>0
		      if  j=10 Then
			       call error(count,j)
				   exit do
              End If
			  
              xsh.Screen.Send(" route  -ne | grep cellular1 | wc -l ")
		      xsh.Screen.Send(VbCr)
              screenrow = xsh.Screen.CurrentRow
              data = xsh.Screen.Get(screenrow-1,1,screenrow-1,20)
		
		      if CInt(Instr(1,data,"4",1)) = "2"  Then
			       xsh.Screen.Send("cellular1 online succfess")
				   xsh.Screen.Send(VbCr)
			       exit do 				   
              End If
			 
			 j = j + 1
			 xsh.Session.Sleep(2000)
		 loop
		 if j=10 then
		    exit do
		 end if
		 count = count +1
		 xsh.Session.Sleep(20000)
   Loop
   Call reboot()
End Sub

6、对象

Sub Main
	'xsh.Session.Open("C:\...\NetSarang\Xshell\Sessions\New Session.xsh")
	Dim count:count = 1
	while count > 0
		xsh.Screen.Synchronous = true
		
		xsh.Screen.Send("reboot")
		xsh.Screen.Send(VbCr)
		xsh.Session.Sleep(150000)
		
		'*** WaitForString ***
		xsh.Screen.Send(VbCr)
		xsh.Screen.WaitForString("login")
		
		'*** Send ***
		xsh.Screen.Send("root")
		xsh.Screen.Send(VbCr)
		xsh.Session.Sleep(3000)
		xsh.Screen.Send(VbCr)
		xsh.Screen.Send(VbCr)
		
        '*** 赋值用dim 定义值jkl并同时赋jkl值0***                   
              Dim jkl:jkl = 0
        '*** while 循环 while开始 Wend结束 ***
              while jkl = 0
            '*** vbs像xshell内部发送执行命令 ***
            xsh.Screen.Send("cat /etc/dhcp3/dhcpd6.leases | grep 2001::5656: |wc -l")
            '*** 回车，发送一条命令就回车一次，要不不执行***
		      xsh.Screen.Send(VbCr) 
            '*** 等待20s***
                                      xsh.Session.Sleep(20000) 
            '*** 使用查找字符串固定条款***
		      screenrow = xsh.Screen.CurrentRow
            '*** 获取xshell当前打印内容，这里是读取其最末行40个字符，第一个参数和第三个参数固定 ***
		      data = xsh.Screen.Get(screenrow-1,1,screenrow-1,20) 
                
                '*** instr( start_position，string1, string2,nth_appearance )
'***
              if CInt(Instr(1,data,"1",1)) = "1" Then
                  jkl = 1
              End If
                '***if 语句格式 if  判断条件 Then 有else就加else 没有就End If***
              Wend


		screenrow = xsh.Screen.CurrentRow
		data = xsh.Screen.Get(screenrow-1,1,screenrow-1,20)
		if CInt(Instr(1,data,"1",1)) = "0" Then
			xsh.Screen.Send("cat /etc/dhcp3/dhcpd6.leases | grep 2001::5656: |wc -l")
			xsh.Screen.Send(VbCr)
		
			xsh.Session.Sleep(40000)
			screenrow = xsh.Screen.CurrentRow
			data = xsh.Screen.Get(screenrow-1,1,screenrow-1,20)
			if CInt(Instr(1,data,"1",1)) = "0" Then

				count = 0
