是否使用javascript检查对角线、垂直线和水平线上的4行？

要检查一个4x4的棋盘上是否有连续的四个相同的符号（如在国际象棋、五子棋或井字棋等游戏中），你可以使用JavaScript来遍历棋盘的每个单元格，并检查每个方向（水平、垂直和对角线）是否有连续的四个相同符号。以下是一个简单的示例代码，展示了如何实现这一功能：

function checkWin(board, player) {
    // 检查水平线
    for (let row = 0; row < 4; row++) {
        for (let col = 0; col <= 7; col++) {
            if (board[row][col] === player && board[row][col + 1] === player && board[row][col + 2] === player && board[row][col + 3] === player) {
                return true;
            }
        }
    }

    // 检查垂直线
    for (let row = 0; row <= 7; row++) {
        for (let col = 0; col < 4; col++) {
            if (board[row][col] === player && board[row + 1][col] === player && board[row + 2][col] === player && board[row + 3][col] === player) {
                return true;
            }
        }
    }

    // 检查对角线（左上到右下）
    for (let row = 0; row <= 7; row++) {
        for (let col = 0; col <= 7; col++) {
            if (row <= 3 && col <= 3) {
                if (board[row][col] === player && board[row + 1][col + 1] === player && board[row + 2][col + 2] === player && board[row + 3][col + 3] === player) {
                    return true;
                }
            }
        }
    }

    // 检查对角线（右上到左下）
    for (let row = 0; row <= 7; row++) {
        for (let col = 3; col >= 0; col--) {
            if (row <= 3 && col <= 3) {
                if (board[row][col] === player && board[row + 1][col - 1] === player && board[row + 2][col - 2] === player && board[row + 3][col - 3] === player) {
                    return true;
                }
            }
        }
    }

    return false;
}

// 示例棋盘
const board = [
    ['X', 'O', 'X', 'O'],
    ['O', 'X', 'O', 'X'],
    ['X', 'O', 'X', 'O'],
    ['O', 'X', 'X', 'X']
];

console.log(checkWin(board, 'X')); // 输出：true 或 false，取决于棋盘状态
