js根据路径获取文件名称

function getFileNameByPath(path) {
    return path.split(/[/\\]/).pop();
}

// 示例
const path1 = "/home/user/documents/file.txt";
const path2 = "C:\\Users\\User\\Documents\\file.txt";

console.log(getFileNameByPath(path1)); // 输出: file.txt
console.log(getFileNameByPath(path2)); // 输出: file.txt

function getFileNameByPath(path) {
    const lastIndex = Math.max(path.lastIndexOf('/'), path.lastIndexOf('\\'));
    return path.substring(lastIndex + 1);
}

// 示例
const path1 = "/home/user/documents/file.txt";
const path2 = "C:\\Users\\User\\Documents\\file.txt";

console.log(getFileNameByPath(path1)); // 输出: file.txt
console.log(getFileNameByPath(path2)); // 输出: file.txt

const path = require('path');

function getFileNameByPath(filePath) {
    return path.basename(filePath);
}

// 示例
const path1 = "/home/user/documents/file.txt";
const path2 = "C:\\Users\\User\\Documents\\file.txt";

console.log(getFileNameByPath(path1)); // 输出: file.txt
console.log(getFileNameByPath(path2)); // 输出: file.txt
