使用vue+ivew做2048小游戏

首先先弄页面 废话不多说 上代码

静态页面代码

<template>
    <div class="main">
        <div class="top">
            <Button type="primary" @click="refresh()">重玩</Button>
            <span style="font-size: 20px;margin-left: 10px;color: red">分数:{{conunta}}</span>
        </div>

        <div class="jiu">
            <div class="grid-cell" id="grid-cell-0-0">
                <div class="cell" v-if="a00">{{a00}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-0-1">
                <div class="cell" v-if="a01">{{a01}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-0-2">
                <div class="cell" v-if="a02">{{a02}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-0-3">
                <div class="cell" v-if="a03">{{a03}}</div>
            </div>

            <div class="grid-cell" id="grid-cell-1-0">
                <div class="cell" v-if="a10">{{a10}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-1-1">
                <div class="cell" v-if="a11">{{a11}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-1-2">
                <div class="cell" v-if="a12">{{a12}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-1-3">
                <div class="cell" v-if="a13">{{a13}}</div>
            </div>

            <div class="grid-cell" id="grid-cell-2-0">
                <div class="cell" v-if="a20">{{a20}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-2-1">
                <div class="cell" v-if="a21">{{a21}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-2-2">
                <div class="cell" v-if="a22">{{a22}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-2-3">
                <div class="cell" v-if="a23">{{a23}}</div>
            </div>

            <div class="grid-cell" id="grid-cell-3-0">
                <div class="cell" v-if="a30">{{a30}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-3-1">
                <div class="cell" v-if="a31">{{a31}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-3-2">
                <div class="cell" v-if="a32">{{a32}}</div>
            </div>
            <div class="grid-cell" id="grid-cell-3-3">
                <div class="cell" v-if="a33">{{a33}}</div>
            </div>
        </div>
    </div>
</template>

然后css

.main {
  background: white;
  margin-top: 200px;
}
.top {
  margin: 10px;
}
.jiu {
  background: #ecdede;
  width: 500px;
  height: 500px;
  margin: auto;
  /* top: 100px; */

  padding: 10px;
}
.grid-cell {
  width: 100px;
  height: 100px;
  margin: 10px;
  background: #c3bcae;
  float: left;
  border-radius: 15%;
}
.cell {
  line-height: 100px;
  background: coral;
  border-radius: 15%;
  font-size: 50px;
  color: white;
  font-weight: bold;
}

 最后核心代码
