好的,以下是一个简单的支付密码页面的实现:
1. 首先,在 `pages` 目录下新建一个名为 `payPassword` 的页面,可以使用 uniapp 的模板工具创建。
2. 在 `payPassword.vue` 文件中编写页面结构和样式,例如:
```html
<template>
<view class="pay-password">
<!-- 支付密码标题 -->
<view class="pay-password-title">请输入支付密码</view>
<!-- 密码输入框 -->
<view class="pay-password-input">
<view v-for="(item, index) in password" :key="index" class="pay-password-item" :class="{ 'active': index === currentIndex }">{{ item }}</view>
</view>
<!-- 数字键盘 -->
<view class="pay-password-keyboard">
<view class="pay-password-row">
<view class="pay-password-key" @click="handleInput(1)">1</view>
<view class="pay-password-key" @click="handleInput(2)">2</view>
<view class="pay-password-key" @click="handleInput(3)">3</view>
</view>
<view class="pay-password-row">
<view class="pay-password-key" @click="handleInput(4)">4</view>
<view class="pay-password-key" @click="handleInput(5)">5</view>
<view class="pay-password-key" @click="handleInput(6)">6</view>
</view>
<view class="pay-password-row">
<view class="pay-password-key" @click="handleInput(7)">7</view>
<view class="pay-password-key" @click="handleInput(8)">8</view>
<view class="pay-password-key" @click="handleInput(9)">9</view>
</view>
<view class="pay-password-row">
<view class="pay-password-key"></view>
<view class="pay-password-key" @click="handleInput(0)">0</view>
<view class="pay-password-key pay-password-delete" @click="handleDelete()"></view>
</view>
</view>
</view>
</template>
<style scoped>
.pay-password {
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
height: 100%;
background-color: #fff;
}
.pay-password-title {
font-size: 16px;
margin-bottom: 20px;
}
.pay-password-input {
display: flex;
justify-content: center;
margin-bottom: 20px;
}
.pay-password-item {
width: 20px;
height: 20px;
border: 1px solid #ccc;
margin-right: 10px;
text-align: center;
line-height: 20px;
font-size: 14px;
}
.pay-password-item.active {
border-color: #007aff;
}
.pay-password-keyboard {
display: flex;
flex-wrap: wrap;
justify-content: center;
}
.pay-password-row {
display: flex;
justify-content: center;
margin-bottom: 10px;
}
.pay-password-key {
display: flex;
justify-content: center;
align-items: center;
width: 50px;
height: 50px;
border: 1px solid #ccc;
margin-right: 10px;
font-size: 16px;
}
.pay-password-delete:before {
content: ' ';
display: inline-block;
width: 10px;
height: 10px;
border-left: 1px solid #333;
border-bottom: 1px solid #333;
transform: rotate(-45deg);
}
</style>
```
3. 在 `payPassword.vue` 文件中定义相关数据和方法,例如:
```js
<script>
export default {
data() {
return {
password: ['', '', '', '', '', ''], // 支付密码
currentIndex: 0 // 当前输入的位置
}
},
methods: {
// 处理数字键盘输入
handleInput(num) {
if (this.currentIndex >= this.password.length) return
this.password.splice(this.currentIndex, 1, num.toString())
this.currentIndex++
if (this.currentIndex >= this.password.length) {
// 输入完成
this.$emit('pay', this.password.join(''))
}
},
// 处理数字键盘删除
handleDelete() {
if (this.currentIndex <= 0) return
this.currentIndex--
this.password.splice(this.currentIndex, 1, '')
}
}
}
</script>
```
4. 在需要使用支付密码的页面中引入 `payPassword` 组件,并监听 `pay` 事件获取支付密码,例如:
```html
<template>
<view>
<!-- 显示支付密码输入框 -->
<pay-password @pay="handlePay"></pay-password>
</view>
</template>
<script>
import PayPassword from '@/pages/payPassword.vue'
export default {
components: {
PayPassword
},
methods: {
// 处理支付密码输入完成
handlePay(value) {
console.log('支付密码:', value)
// TODO: 在这里调用支付接口进行支付
}
}
}
</script>
```
以上就是一个简单的支付密码页面的实现方法。当用户输入完成支付密码后,会触发 `pay` 事件并将支付密码传递给父组件,父组件可以在事件回调函数中进行支付操作。当然,这只是一个简单的示例,实际的支付密码页面需要考虑更多的安全性和用户体验问题。
