Powershell 菜单和子菜单

主菜单：

1 Delete 2 Create 3 Modify 4 Remove X Exit 子菜单1

$su1 = Read-Host "
Please select an option
1 Delete a file
2 Delete a folder
3 Delete another file
4 Delete another folder
5 Back to main menu
"

如何选择选项5并将其返回主菜单？

您可以通过开关为每个菜单创建函数，以便继续调用新菜单

function mainMenu(){
    clear
    switch(Read-Host "1 Delete
2 Create
3 Modify
4 Remove
X Exit"){
        X {break}
        2 {createMenu}
        default {"N/A"}
    }
}

function createMenu(){
    clear
    switch(Read-Host "Please select an option `
1 Delete a file
2 Delete a folder
3 Delete another file
4 Delete another folder
5 Back to main menu"){
        5 {mainMenu}
        default {"N/A"}
    }
}

mainMenu

将子菜单放入函数中，将主菜单放入循环中，然后从该循环中调用子菜单函数。与此类似吗？不完全是。更重要的是，只有子菜单在函数中有自己的循环。请注意，PowerShell中存在多个。 1 Modify Virtual 2 Modify another Virtual 3 Back to Main Menu

$q = Read-Host "
Please select an option:
1 Delete Files 
2 Create New Virtual
3 Modify Existing Virtual
"

$su1 = Read-Host "
Please select an option
1 Delete a file
2 Delete a folder
3 Delete another file
4 Delete another folder
5 Back to main menu
"

function mainMenu(){
    clear
    switch(Read-Host "1 Delete
2 Create
3 Modify
4 Remove
X Exit"){
        X {break}
        2 {createMenu}
        default {"N/A"}
    }
}

function createMenu(){
    clear
    switch(Read-Host "Please select an option `
1 Delete a file
2 Delete a folder
3 Delete another file
4 Delete another folder
5 Back to main menu"){
        5 {mainMenu}
        default {"N/A"}
    }
}
