3 - 语法-不区分大小写

3.1 注释;

3.2 数据类型

$fBoolean1 = True;	//boolea值
$fBoolean2 = False

//二进制
$bin = Binary("abc")
$str = String($bin)    ; "0x616263"

//指针Pointer

3.3 变量$xX

Local $vVariabl=1;	//局部变量
Global $vVariable1="xx", $vVariable2;	//全局变量
Const $iConst1 = 1, $iConst2 = 12;		//静态变量

//数组
Local $aArray[4];
$aArray[0]="asdasd";
Local $aArray[7] = [3, 7.5, "string"]
$aArray[0] == "xx";		//取值

3.4 操作符

//其它符号同常用含义
& //连接字符串, "one" & 10=="one10"
<> //是否不相等，等同 Not ("string1" == "string2")
And //If $vVar = 5 And $vVar2 > 6 Then
Or //If $vVar = 5 Or $vVar2 > 6 Then
Not //Not 1
? : //三目运算符

3.5 条件语句

//以下所有，如果一个条件成立，则后面所有条件都被忽略
a). If...Then...Else
b). Select...Case
c). Switch...Case
d). Ternary

3.5.1 示例1

#include <Constants.au3>
If $iNumber > 0 Then
MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was positive!")
ElseIf $iNumber < 0 Then
	MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was negative!")
Else
	MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was zero.")
EndIf 

3.5.2 示例2, 代替多分的if else

Select
	Case $iNumber > 1 And $iNumber <= 10
		MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was greater than 1")

	Case $iNumber > 10 And $iNumber <= 20
		MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was greater than 10")

	Case $iNumber > 20 And $iNumber <= 30
		MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was greater than 20")

	Case $iNumber > 30 And $iNumber <= 40
		MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was greater than 30")

	Case $iNumber > 40
		MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was greater than 40")
EndSelect 

3.5.3 示例3

Local $iNumber = 30
Switch Int($iNumber)
	Case 1 To 10
		MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was greater than 1")
	Case 11 To 20
		MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was greater than 10")
	Case 21 To 30
		MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was greater than 20")
	Case 31 To 40
		MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was greater than 30")
	Case Else
		MsgBox($MB_SYSTEMMODAL, "Example", "$iNumber was greater than 40 or less or equal to 0")
EndSwitch 

3.6 循环

a). For...Next
b). While...WEnd
c). Do...Until
d). For...In...Next (可遍历对象节点)
e). ExitLoop 终止while/do/for循环(类似break)
ContinueLoop 继续循环(continue)

	//示例1
	For $i = 5 To 1 Step -1
		MsgBox($MB_SYSTEMMODAL, "", "Count down!" & @CRLF & $i)
	Next
	
	//示例2
	Local $i = 0
	While $i <= 10
		MsgBox($MB_SYSTEMMODAL, "", "Value of $i is: " & $i)
		$i = $i + 1
	WEnd
	
	//示例3
	Local $i = 0
	Do
		MsgBox($MB_SYSTEMMODAL, "", "The value of $i is: " & $i) ; 
		$i = $i + 1 ; 
	Until $i = 10 ;
	
	//示例4--遍历数组或对象节点
	For $Window In $oShellWindows
		$sString = $sString & $Window.LocationName & @CRLF
	Next

3.7 自定义函数Func...EndFunc

$iDoubled = MyDouble($iNumber);
Func MyDouble($iValue)
	$iValue = $iValue * 2
	Return $iValue
EndFunc
