【uni-app】通过uni-app基础组件picker实现选择日期、时间的功能示例（完整代码+图文）

一、获取日期（基础）

<template>
	<view class="container">
		<picker mode="date" @change="onDateChange" :value="date">
			<view class="date-picker">{{date}}</view>
		</picker>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				date: '请选择日期'
			}
		},
		methods: {
			onDateChange: function(e) {
				this.date = e.detail.value;
			}
		}
	}
</script>

<style>
	.container {
		padding: 20rpx;
		background-color: #f5f5f5;
	}

	.date-picker {
		line-height: 80rpx;
		border: 1px solid #***c;
		padding: 10rpx;
		text-align: center;
		background-color: #fff;
	}
</style>

二、获取日期和时间（改进）

<template>
	<view>
			<!--日期选择-->
			<view class="SelectDate">
				<view class="DateLabel">
					预定日期
				</view>
				<view class="DateText">
					<picker mode="date" @change="onDateChange" :value="DateValue">
						<view class="date-picker">{{DateValue}}</view>
					</picker>
				</view>
			</view>

			<view class="SelectTime">
				<view class="TimeLabel">
					预定时间
				</view>
				<view class="TimeText">
					<picker mode="time" @change="onTimeChange" :value="TimeValue">
						<view class="Time-picker">{{TimeValue}}</view>
					</picker>
				</view>
			</view>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				DateValue: "点击选择日期",
				TimeValue: "点击选择时间",
			}
		},
		methods: {
			
			onDateChange: function(e) {
				this.DateValue = e.detail.value;
			},

			onTimeChange: function(e) {
				this.TimeValue = e.detail.value;
			},
			}
	}
</script>

<style scoped>
