vue,一路走来(14)--短信验证码框的实现(类似支付密码框)

由于项目的扩展,新增了很多功能,今天谈一下短信验证码框的实现。

思路:每个小方框其实就是单独的每一个input标签(叫假input标签),每个长度为1,然后上面再写一个大的input标签(叫真实input标签),提高层级定位在上方,最大长度为6,然后将上方真实input标签的值传给每一个单独的假input标签。

<div class="phonenum-show">
     <div class="getback-title">收回剩余礼金 
<span @click="getbackMoneyclock()"><img src="../assets/getback.png" alt=""></span>
</div> <div class="write-phonenum"> <p>请输入尾号<span>9909</span>的手机收到的短信验证码</p> <input type="tel" maxlength="6" class="realInput" v-model="realInput" @keyup="getNum()" @keydown="delNum()" id="focusid"> <ul class="write-input clearfix"> <li v-for="disInput in disInputs"><input type="tel" maxlength="1" v-model="disInput.value"></li> </ul> <mt-button size="large">我明白了 确认提交</mt-button> <p>剩余礼金将收回至微信“零钱包”请注意查收。</p> <p style="color:#bfc0c0;">活动结束24小时后可申请收回剩余的礼金。</p> </div> </div>
