这次给大家带来vue引入js数字小键盘步骤详解，vue引入js数字小键盘的注意事项有哪些，下面就是实战案例，一起来看一下。
效果如图：
代码如下：
keyboard.vue
<template>
<p class="keyboard" v-show="showKeyboard" v-clickoutside="closeModal">
<p v-for="keys in keyList">
<template v-for="key in keys">
<i v-if="key === 'top'" @click.stop="clickKey" class="iconfont icon-zhiding tab-top"></i>
<i v-else-if="key === '123'" @click.stop="clickKey" class="tab-num">123</i>
<i v-else-if="key === 'del'" @click.stop="clickKey" id="del" class="iconfont icon-delete key-delete"></i>
<i v-else-if="key === 'blank'" @click.stop="clickKey" class="iconfont icon-konggejian-jianpanyong tab-blank"></i>
<i v-else-if="key === 'symbol'" @click.stop="clickKey" class="tab-symbol">符</i>
<i v-else-if="key === 'point'" @click.stop="clickKey" class="tab-point">·</i>
<i v-else-if="key === 'enter'" @click.stop="clickKey" class="iconfont icon-huiche tab-enter"></i>
<i v-else @click.stop="clickKey" >{{key}}</i>
</template>
</p>
</p>
</template>
<script>

},
clickKey(event) {
// if(event.type === 'click' && this.equip) return
let value = event.srcElement.innerText;
let id = event.srcElement.id;
let target = event.srcElement ? event.srcElement : event.target;

this.emitValue(id);
}else{//否则

}
},
emitValue(key) {
console.log(key)
this.$emit('keyVal', key)
},
closeModal(e) {
