前端Vue自定义发送短信验证码弹框popup 实现剩余秒数计数 重发短信验证码， 请访问uni-app插件市场地址：https://ext.dcloud.net.cn/plugin?id=13207
效果图如下：
实现代码如下:
# cc-codeDialog
#### 使用方法
```使用方法
<!-- show:是否显示弹框 phone:手机号? autoCountdown:自动时间秒数 len:短信验证码长度 @closeClick:关闭弹框 @confirmClick:确认事件 -->
<cc-codeDialog :show="show" phone="1900000000" :autoCountdown="true" :len="6" @closeClick="closeCodeDialog" @confirmClick="confirmClick"></cc-codeDialog>
```
#### HTML代码实现部分
```html
<template>
<view class="content">
<button @click="showCodeDialog">发送短信验证码 </button>
<!-- show:是否显示弹框 phone:手机号? autoCountdown:自动时间秒数 len:短信验证码长度 @closeClick:关闭弹框 @confirmClick:确认弹框 -->
<cc-codeDialog :show="show" phone="1900000000" :autoCountdown="true" :len="6" @closeClick="closeCodeDialog"
@confirmClick="confirmClick"></cc-codeDialog>
</view>
</template>
<script>
export default {
data() {
return {
show: false
}
},
methods: {
showCodeDialog(item) {
this.show = true;
},
closeCodeDialog(item) {
this.show = false;
},
confirmClick(result) {
console.log("result = " + JSON.stringify(result));
this.show = false;
}
}
}
</script>
<style>
.content {
display: flex;
flex-direction: column;
background-color: aliceblue;
height: 100vh;
}
</style>
```
