我来为您介绍几种快速构建菜单的脚本方法,涵盖不同场景和语言。

Shell脚本 - 交互式菜单

#!/bin/bash
# 简单的交互式菜单
show_menu() {
    clear
    echo "=========================="
    echo "    系统管理菜单"
    echo "=========================="
    echo "1. 查看系统信息"
    echo "2. 查看磁盘使用"
    echo "3. 查看内存使用"
    echo "4. 查看进程"
    echo "0. 退出"
    echo "=========================="
}
while true; do
    show_menu
    read -p "请输入选项: " choice
    case $choice in
        1) echo "系统信息:"; uname -a;;
        2) df -h;;
        3) free -h;;
        4) ps aux;;
        0) echo "再见!"; exit 0;;
        *) echo "无效选项";;
    esac
    read -p "按回车继续..."
done

Python - 使用curses库

#!/usr/bin/env python3
import curses
import subprocess
def main(stdscr):
    # 初始化颜色
    curses.start_color()
    curses.init_pair(1, curses.COLOR_CYAN, curses.COLOR_BLACK)
    curses.init_pair(2, curses.COLOR_YELLOW, curses.COLOR_BLACK)
    menu_items = [
        "系统信息",
        "磁盘使用",
        "内存状态",
        "网络配置",
        "退出"
    ]
    current_row = 0
    while True:
        stdscr.clear()
        stdscr.addstr(0, 0, "=== 系统工具菜单 ===", curses.color_pair(1))
        for idx, item in enumerate(menu_items):
            if idx == current_row:
                stdscr.addstr(idx + 2, 0, f"> {item}", curses.color_pair(2))
            else:
                stdscr.addstr(idx + 2, 0, f"  {item}")
        key = stdscr.getch()
        if key == curses.KEY_UP and current_row > 0:
            current_row -= 1
        elif key == curses.KEY_DOWN and current_row < len(menu_items) - 1:
            current_row += 1
        elif key == ord('\n'):
            if current_row == len(menu_items) - 1:
                break
            elif current_row == 0:
                stdscr.addstr(10, 0, subprocess.getoutput("uname -a"))
        stdscr.refresh()
    curses.endwin()
if __name__ == "__main__":
    curses.wrapper(main)

Bat脚本 - Windows菜单

@echo off
chcp 65001 >nul
:menu
cls
echo ==========================
echo    Windows系统工具
echo ==========================
echo 1. 查看IP配置
echo 2. 磁盘清理
echo 3. 系统信息
echo 4. 进程列表
echo 0. 退出
echo ==========================
set /p choice=请输入选项: 
if "%choice%"=="1" ipconfig
if "%choice%"=="2" cleanmgr
if "%choice%"=="3" systeminfo
if "%choice%"=="4" tasklist
if "%choice%"=="0" exit /b
pause
goto menu

JavaScript - Web菜单

<!DOCTYPE html>
<html>
<head>
<style>
    .menu-container {
        max-width: 300px;
        margin: 20px auto;
    }
    .menu-item {
        display: block;
        width: 100%;
        padding: 12px;
        margin: 5px 0;
        background: #f0f0f0;
        border: 1px solid #ddd;
        cursor: pointer;
        transition: background 0.3s;
    }
    .menu-item:hover {
        background: #e0e0e0;
    }
    .menu-item.active {
        background: #007bff;
        color: white;
    }
</style>
</head>
<body>
<div class="menu-container">
    <h2>快速任务菜单</h2>
    <button class="menu-item" data-action="info">系统信息</button>
    <button class="menu-item" data-action="backup">数据备份</button>
    <button class="menu-item" data-action="clean">清理缓存</button>
    <button class="menu-item" data-action="report">生成报告</button>
</div>
<script>
document.querySelectorAll('.menu-item').forEach(item => {
    item.addEventListener('click', function() {
        // 高亮当前选中
        document.querySelectorAll('.menu-item').forEach(i => 
            i.classList.remove('active')
        );
        this.classList.add('active');
        // 根据动作执行对应功能
        const action = this.dataset.action;
        switch(action) {
            case 'info':
                alert('获取系统信息...');
                break;
            case 'backup':
                alert('开始备份...');
                break;
            case 'clean':
                alert('清理缓存...');
                break;
            case 'report':
                alert('生成报告...');
                break;
        }
    });
});
</script>
</body>
</html>

PowerShell - 动态菜单

function Show-Menu {
    param(
        [string]$Title = "系统管理"
    )
    Clear-Host
    Write-Host "======================" -ForegroundColor Cyan
    Write-Host "   $Title" -ForegroundColor Yellow
    Write-Host "======================" -ForegroundColor Cyan
    Write-Host "1. 查看系统信息"
    Write-Host "2. 网络诊断"
    Write-Host "3. 服务管理"
    Write-Host "4. 事件日志"
    Write-Host "Q. 退出"
    Write-Host "======================" -ForegroundColor Cyan
}
do {
    Show-Menu
    $selection = Read-Host "请选择"
    switch ($selection) {
        '1' {
            Get-ComputerInfo | Select-Object WindowsVersion, WindowsBuildLabEx
            pause
        }
        '2' {
            Test-NetConnection google.com
            pause
        }
        '3' {
            Get-Service | Where-Object {$_.Status -eq "Stopped"} | 
                Select-Object Name, Status, DisplayName
            pause
        }
        '4' {
            Get-EventLog -LogName System -Newest 10 | 
                Format-Table TimeGenerated, EntryType, Message -Wrap
            pause
        }
        'q' {
            break
        }
        'Q' {
            break
        }
    }
} while ($true)

快速构建技巧

模板化菜单

# 定义菜单项数组
menu_items=(
    "功能1:command1"
    "功能2:command2"
    "功能3:command3"
)
# 通用菜单生成器
generate_menu() {
    local title=$1
    shift
    local items=("$@")
    echo "=== $title ==="
    for i in "${!items[@]}"; do
        echo "$((i+1)). ${items[$i]%%:*}"
    done
    echo "0. 退出"
}

JSON配置文件

{
    "menu": {
        "title": "系统工具",
        "items": [
            {"name": "系统信息", "command": "uname -a"},
            {"name": "磁盘使用", "command": "df -h"},
            {"name": "内存状态", "command": "free -h"}
        ]
    }
}

选择哪种方法取决于您的具体需求：

• 命令行环境：Shell/Bat脚本
• 跨平台：Python
• Web界面：JavaScript
• Windows管理：PowerShell

希望这些示例能帮您快速构建所需的菜单系统！
