本文实例为大家分享了vue实现移动端H5数字键盘组件的使用代码，供大家参考，具体内容如下
我们平时扫码付款的时候，经常会输入一些数字进行付款，仔细看了下键盘和系统的键盘有点不一样，于是今天买甘蔗的时候扫码付款就想了一下要怎么去实现一个。话不多说，直接上代码。
结果如下：
代码如下：
<template>
<div class="keyboard-wrapper">
<input type="text" v-model="NUM" @focus="show = true" onfocus="this.blur()"/>
<div class="keyboard" v-if="show">
<div class="num">
<table>
<tr>
<td @click="change(1)" :class="[active === 1 " @touchstart="msDown(1)" @touchend="msUp(1)">1</td>
<td @click="change(2)" :class="[active === 2 " @touchstart="msDown(2)" @touchend="msUp(2)">2</td>
<td @click="change(3)" :class="[active === 3 " @touchstart="msDown(3)" @touchend="msUp(3)">3</td>
<td rowspan="2" class="del" @click="del">×</td>
</tr>
<tr>
<td @click="change(4)" :class="[active === 4 " @touchstart="msDown(4)" @touchend="msUp(4)">4</td>
<td @click="change(5)" :class="[active === 5 " @touchstart="msDown(5)" @touchend="msUp(5)">5</td>
<td @click="change(6)" :class="[active === 6 " @touchstart="msDown(6)" @touchend="msUp(6)">6</td>
</tr>
<tr>
<td @click="change(7)" :class="[active === 7 " @touchstart="msDown(7)" @touchend="msUp(7)">7</td>
<td @click="change(8)" :class="[active === 8 " @touchstart="msDown(8)" @touchend="msUp(8)">8</td>
<td @click="change(9)" :class="[active === 9 " @touchstart="msDown(9)" @touchend="msUp(9)">9</td>
<td rowspan="2" class="comfirm" @click="comfirm">确定</td>
</tr>
<tr>
<td colspan="2" @click="change(0)" :class="[active === 0 " @touchstart="msDown(0)" @touchend="msUp(0)">0</td>
<td colspan="1" @click="change('.')" :class="[active === '.' " @touchstart="msDown('.')" @touchend="msUp('.')">.</td>
</tr>
</table>
</div>
</div>
</div>
</template>
<script>
export default {

} else {
this.result.push(val);
this.NUM = this.result.join('');
}
},
del () {
this.result.pop();
this.NUM = this.result.join('');
this.$emit('del', this.NUM);
},
comfirm () {
this.$emit('comfirm', this.NUM);
this.show = false;
}
}
};
</script>
