说实话，uniapp和uview的关于只有时分秒的组件实在是不行。全是日历，但是实际根本就不需要日历这玩意。百度了下，终于看到了一个只有时分秒的组件。原地址：原地址，如若侵犯请联系我删除

<style lang='scss' scoped>
.picker-view {height: 400rpx;background: #fff;
}
.item {line-height: 100rpx;text-align: center;
}
.hmsText {width: 160rpx;height: 50rpx;line-height: 50rpx;border: 1px solid #ddd;text-align: center;background: #fff;border-radius: 10rpx;margin-left: 10rpx;

}
</style>父组件使用：
<uniHms hmsval="21:20:00" @complete="complete" />然后实际效果是：
兄弟搞得不错！可惜了我需要一个时间段！！！ 但是这是个很好的例子。于是按照这个修改加了一个时间段的时分秒选择器。（这里我试了其他样式，终究选了一个自己满意的时间范围选择格式，如果需要可以自行修改样式，大致逻辑方法是不变的）
先上代码：
<template><view class="hms"><!-- //显示时间的地方，样式可以自行修改 --><view class="hmsText" @click="show">{{ hmsVal_start + '-' + hmsVal_end }}</view><!-- //弹出选择时间的弹框 --><uni-popup ref="popup" type="bottom" background-color="#fff"><view class="hms_content"><view class="hmsBtn"><view class="close" @click="close">取消</view><view class="tip">{{ hmsVal_start + '至' + hmsVal_end }}</view><view class="complete" @click="completeFun">完成</view></view><view class="picker"><picker-view indicator-style="100rpx" @change="bindChange" class="picker-view" :value="pickerArrIndexLeft"><picker-view-column><view class="item" v-for="(item, index) in hours" :key="index">{{ item }}时</view></picker-view-column><picker-view-column><view class="item" v-for="(item, index) in minute" :key="index">{{ item }}分</view></picker-view-column><picker-view-column><view class="item" v-for="(item, index) in second" :key="index">{{ item }}秒</view></picker-view-column></picker-view><view class="line">-</view><picker-view indicator-style="100rpx" @change="bindChange2" class="picker-view" :value="pickerArrIndexRight"><picker-view-column><view class="item" v-for="(item, index) in hours" :key="index">{{ item }}时</view></picker-view-column><picker-view-column><view class="item" v-for="(item, index) in minute" :key="index">{{ item }}分</view></picker-view-column><picker-view-column><view class="item" v-for="(item, index) in second" :key="index">{{ item }}秒</view></picker-view-column></picker-view></view></view></uni-popup></view>

</style>父组件：
<uniHms hmsval="21:20:00-23:56:00" @complete="complete" />格式是时间-时间。
然后页面显示效果图：
欧耶，完成！！！需要的和不需要的赶紧收藏起来，只要干这行的说不定哪天就需要用到呢！！！！
另外补充一句，uniapp组件文档很鸡肋哎。。。
