用UNIAPP实现一个时间选择器,包括年(前5年后5年)、月、日、时、分 要求间隔10分钟 且要考虑到月份的日子

首先,需要引入uni-app官方提供的日期选择器组件 `uni-datetime-picker`,具体使用方法可以查看官方文档。
然后,我们需要对日期选择器进行一些配置,满足题目要求。具体来说,可以按照以下步骤进行:
1. 配置年份范围:根据题目要求,我们需要选择前5年和后5年的年份,可以使用 JavaScript 的 `Date` 对象来获取当前年份,然后设置 `startYear` 和 `endYear` 的值。
```js
const currentYear = new Date().getFullYear()
const startYear = currentYear - 5
const endYear = currentYear + 5
```
2. 配置月份范围:月份范围为1~12,直接设置即可。
```js
const startMonth = 1
const endMonth = 12
```
3. 配置日期范围:需要考虑到月份的日子,可以使用 JavaScript 的 `Date` 对象的 `getDate()` 方法来获取某个月份的天数,然后根据天数设置日期范围。
```js
const selectedMonthDays = new Date(selectedYear, selectedMonth, 0).getDate()
const startDay = 1
const endDay = selectedMonthDays
```
4. 配置时间范围:需要间隔10分钟,可以使用循环来生成时间列表。
```js
const startHour = 0
const endHour = 23
const startMinute = 0
const endMinute = 50
const minuteInterval = 10
const timeList = []
for (let hour = startHour; hour <= endHour; hour++) {
for (let minute = startMinute; minute <= endMinute; minute += minuteInterval) {
timeList.push(`${hour.toString().padStart(2, '0')}:${minute.toString().padStart(2, '0')}`)
}
}
```
最后,将以上配置项传递给 `uni-datetime-picker` 组件即可。
```html
<template>
<view>
<uni-datetime-picker
mode="datetime"
:start-year="startYear"
:end-year="endYear"
:start-month="startMonth"
:end-month="endMonth"
:start-day="startDay"
:end-day="endDay"
:hour-list="timeList.map(time => time.split(':')[0])"
:minute-list="timeList.map(time => time.split(':')[1])"
></uni-datetime-picker>
</view>
</template>
<script>
export default {
data() {
const currentYear = new Date().getFullYear()
const startYear = currentYear - 5
const endYear = currentYear + 5
const startMonth = 1
const endMonth = 12
const selectedYear = currentYear
const selectedMonth = new Date().getMonth() + 1
const selectedMonthDays = new Date(selectedYear, selectedMonth, 0).getDate()
const startDay = 1
const endDay = selectedMonthDays
const startHour = 0
const endHour = 23
const startMinute = 0
const endMinute = 50
const minuteInterval = 10
const timeList = []
for (let hour = startHour; hour <= endHour; hour++) {
for (let minute = startMinute; minute <= endMinute; minute += minuteInterval) {
timeList.push(`${hour.toString().padStart(2, '0')}:${minute.toString().padStart(2, '0')}`)
}
}
return {
startYear,
endYear,
startMonth,
endMonth,
selectedYear,
selectedMonth,
startDay,
endDay,
startHour,
endHour,
startMinute,
endMinute,
minuteInterval,
timeList
}
}
}
</script>
```
