Question

我有一个问题我无法解决AHK问题。我的代码：

begin()

begin() {
    Global Input
    Gui, Add, Edit, vInput gInputChanged
}

InputChanged() {
    MsgBox, Your input is %Input%
}

很简单，嗯？但是，当触发InputChanged()时，变量Input永远不会正确（它始终为空）。

Answer 1

请参阅Function Variables and Scope

示例：

Input := "Hello" ; Our Variable Defined outside of our Function

begin() ; Call the function passing no Variables

begin() {
    Global Input
    MsgBox, Global! Input = %Input%
    InputChangedLocally(Input) ; Pass the Input variable which is 'Hello'

}

InputChangedLocally(Input) {
    Input .= " World!" ; Change Local variable
    MsgBox, Changed Locally %Input%
    OnlyGlobalInput()
}

OnlyGlobalInput() {
    Global Input

     ; Notice it is not 'Hello World!' even though we changed it above!

    MsgBox, Global! Input = %Input%
    InputNotPassedOrGlobal()
}

InputNotPassedOrGlobal() {
    MsgBox, Your input is %Input% ; Blank as we never accessed any thing!
}

AHK Gui添加编辑变量无法访问
