【nodejs】Vue手把手入门指南：教你做扫雷

在Node.js环境中搭建Vue项目并实现扫雷游戏的基本功能可以分成以下几个步骤：

1. 安装Node.js和npm。
2. 安装Vue CLI：npm install -g @vue/cli。
3. 创建一个新的Vue项目：vue create miner-sweeper。
4. 进入项目目录：cd miner-sweeper。
5. 安装项目依赖：npm install。
6. 启动开发服务器：npm run serve。

以下是简化的扫雷游戏实现示例：

<template>
  <div class="mine-sweeper">
    <table>
      <tr v-for="row in rows" :key="row">
        <td v-for="col in cols" :key="col">
          <button
            v-if="!isRevealed(row, col)"
            @click="reveal(row, col)"
          >
            {{ getCellContent(row, col) }}
          </button>
          <span v-else>{{ getCellContent(row, col) }}</span>
        </td>
      </tr>
    </table>
  </div>
</template>
 
<script>
export default {
  data() {
    return {
      rows: 10,
      cols: 10,
      mines: 10,
      board: [],
    };
  },
  created() {
    this.initializeBoard();
  },
  methods: {
    initializeBoard() {
      this.board = new Array(this.rows).fill(null).map(() =>
        new Array(this.cols).fill(null).map(() => ({ content: '0', revealed: false }))
      );
      this.placeMines();
      this.calculateNeighbors();
    },
    placeMines() {
      let minesPlaced = 0;
      while (minesPlaced < this.mines) {
        const row = Math.floor(Math.random() * this.rows);
        const col = Math.floor(Math.random() * this.cols);
        if (this.board[row][col].content !== 'X') {
          this.board[row][col].content = 'X';
          minesPlaced++;
        }
      }
    },
    calculateNeighbors() {
      for (let row = 0; row < this.rows; row++) {
        for (let col = 0; col < this.cols; col++) {
          if (this.board[row][col].content !== 'X') {
            this.board[row][col].content = this.countNeighborMines(row, col);
          }
        }
      }
    },
    countNeighborMines(row, col) {
      return [
        this.getCell(row - 1, col - 1),
        this.getCell(row - 1, col),
        this.getCell(row - 1, col + 1),
        this.getCell(row, col - 1),
        this.getCell(row, col + 1),
        this.getCell(row + 1, col - 1),
        this.getCell(row + 1, col),
        this.getCell(row + 1, col + 1),
      ].filter(cell => cell && cell.content === 'X').length;
    },
    getCell(row, col) {
      return this.isValidCell(row, col) ? this.board[row][col] : null;
    },
    isValidCell(row, col) {
      return row >= 0 && row < this.rows && col >= 0 && col < this.cols;
