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

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">

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。。。
