Language Reference - Variables
所谓变量是指在为了快速读取而在内存中保存数据的一块空间。您可以把它想象成是一个在内存里的邮箱,我们可以往里面存信也可以取信。例如您可以创建一个变量用来保存用户回复的数值或者某个数学表达式的运算结果。
每个变量都有自己的名字(这跟邮箱是不是很像?)而且必须以英文字符“$”开头,其中只能包含 字母、数字 和下划线“_”。下面是一些有效的变量名:
$var1
$my_variable
AutoIt 中的每个变量都是 Variant 类型。
变量的声明
AutoIt 中使用关键字 Dim、Local 和 Global 来声明并创建变量:
Dim $var1
还可以像下面这样一次声明多个变量:
Dim $var1, $myvariable
另外还可以不先声明某个变量而直接对其赋值,但最好还是要显式的声明一下。
$var1 = "创建变量并赋值"
变量的作用域
某个变量的作用域要看您是何时以及如何声明该变量的。如果您在脚本开头且在所有函数之外声明了某个变量则该变量将在 全局 范围内存在,此时您就可以在脚本的任意位置读取或更改该变量,我们把这种变量称为全局变量。
如果您是在某个 函数 内部声明一个变量则该变量就只在该函数的 局部 范围内有效,我们把这种变量称为局部变量。在函数内创建的变量将在函数结束时自动被销毁。
在默认情况下,使用 Dim 声明的变量或在函数内部直接赋值而成的变量都是 局部变量,除非 有同名的全局变量存在(此时将视此变量为该全局变量)。另外我们可以使用关键字 Local 和 Global 来声明变量以 控制 变量的作用域。
