vue实现井字棋游戏

本文实例为大家分享了vue实现井字棋游戏的具体代码，供大家参考，具体内容如下

之前看react的教程时看到的小游戏，试着用vue做一个。右边的winner提示胜者，还没有胜者时提示下一个棋子的种类。restart按钮点击可重新开始。go to step可跳转到第n步。

html：

<div id="app">
 <ul id="board" class="white normal">
 <li class="square" v-for="i, idx in datas" @click=set(idx)>{{i}}</li>
 </ul>
 <div id="console">
 <div id="hint" class="white">{{hint}}</div>
 <input type="button" class="white" id="restart" value="restart" @click="init()"/>
 <ul id="history" class="normal">
  <li class="history" v-for="i, idx in history">
  <input type="button" class="white" :value="'go to step' + (idx + 1)" @click=jump(idx) />
  </li>
 </ul>
 </div>
</div>

css：

<style type="text/css">
 body {
 background: #5af;
 }
 
 .white {
 background: #fff;
 border-radius: 11px;
 outline: none;
 border: none;
 }
 
 .normal {
 list-style: none;
 padding: 0px;
 margin: 0px;
 }
 
 #app {
 display: flex;
 justify-content: space-between;
 width: 450px;
 height: 306px;
 position: absolute;
 top: 0;
 bottom: 0;
 left: 0;
 right: 0;
 margin: auto;
 }
 
 #board {
 display: flex;
 width: 306px;
 height: 306px;
 flex-wrap: wrap;
 overflow: hidden;
 }
 
 #hint {
 width: 100px;
 height: 22px;
 text-align: center;
 margin: 10px;
 }
 
 #restart {
 width: 70px;
 height: 22px;
 margin: 10px;
 }
 
 #history，
 .history {
 margin: 5px;
 }
 
 .square {
 height: 100px;
 width: 100px;
 border: #ebebeb solid 1px;
 flex: 0 0 auto;
 font-size: 50px;
 font-weight: 900;
 line-height: 100px;
 text-align: center;
 }
</style>

js：

new vue({
 el: '#app',
 data: {
 datas: array(9).fill(''),
 history: [],
 next: true,
 winner: '',
 cases: [
  [0, 1, 2],
  [3, 4, 5],
  [6, 7, 8],
  [0, 3, 6],
  [1, 4, 7],
  [2, 5, 8],
  [0, 4, 8],
  [2, 4, 6],
 ]
 },
 methods: {
 //放置棋子
 set(idx) {
  if (!this.datas[idx] && !this.winner) {
  this.$set(this.datas, idx, this.next_player);
  this.history.push({
   status: [...this.datas],
   player: this.next
  });
  if (this.is_win(this.next_player)) {
   this.winner = this.next_player;
  }
  this.next = !this.next;
  }
 },
 //跳转到第n步
 jump(idx) {
  this.datas = this.history[idx].status;
  this.history.splice(idx + 1, this.history.length - idx - 1);
  this.next = !this.history[idx].player;
  this.winner = this.is_win('o') 
  ? 'o' 
  : this.is_win('x') 
   ? 'x' 
   : '';
 },
 //判断是否胜出
 is_win(player) {
  return this.cases.some(arr => arr.every(el => this.datas[el] === player));
 },
 //初始化
 init() {
  this.datas = array(9).fill('');
  this.history = [];
  this.next = true;
  this.winner = '';
 }
 },
 computed: {
 next_player() {
  return this.next ? 'o' : 'x';
 }，
 hint() {
  return this.winner ? 'winner: ' + this.winner : 'next: ' + this.next_player;
 }
 }
})
