perl 控制结构 条件控制 if while
一、条件判断if ( ) {}elsif ( ) {}...else{} 二、循环:1、while循环while ( ) {} 2、until循环until ( ) {} 3、类C的for循环 ,如for ($count=1; $count , $count = 1; $count , $co

实现代码如下: '排序 Function Sort1(ary) Dim KeepChecking,I,FirstValue,SecondValue KeepChecking = TRUE Do Until KeepChecking = FALSE KeepChecking = FALSE For I
合并文本的脚本可以这么写: 实现代码如下:Sub AppendTextFile(filename) Set objTextFile = objFSO.OpenTextFile(filename, ForReading, true, -2) Do Until objTextFile.AtEndOfSt
Set fso = CreateObject("Scripting.FileSystemObject") Set ws = WScript.CreateObject("WScript.Shell") Count = 0 Do Until Count< -1chksize = fso.GetFo
关键字 def undef 方法定义 module 模块定义 class 类定义 defined? 检查类型 条件语句 if,then,else,elsif,case,when,unless 循环语句 for ,in,while,until,next,break,do,redo,retry,yiel
实现代码如下:set ie = createobject("internetexplorer.application") ie.navigate "about:blank" do until ie.readystate = 4 : wscript.sleep 25 : loop set doc =
实现代码如下:Dim MyValue, Response,data,thisddata="30007|22899|22934"thisd=Split(data, "|", -1, 1)Randomize '初始化随机数生成器。Do Until Response = vbyesMyValue = In
