因我的项目中很多表单要用到日期抉择和工夫抉择的内容，所以基于 picker 封装了日期和工夫抉择的组件。
datePicker
组件内的年份是获得举例往年 100 年以内的年份，可依据工夫须要进行扩容或缩减，月份是 12 个月固定的，每月的天数，依据所选年份和月份进行获取。默认设置以后日期。
<template>
<picker class="picker" id={pickerId} mode="multiSelector" range-key="name" value={dateMltiSelectorValue} onchange={this.dateMultiSelectorChange} oncolumnchange={this.dateMultiSelectorColumnChange}>

</picker></template>
<script>
export default {

this.initDateData();},

timePicker
时、分、秒都是固定的，组件初始是默认的以后工夫。
<template>
<picker class="picker" id={pickerId} mode="multiSelector" range-key="name" value={timeMltiSelectorValue} onchange={this.timeMultiSelectorChange}>
<text class="picker-label">{timeDesc}</text>
</picker></template>
<script>
export default {
name: 'timePicker',
props:{
label:String,
pickerId:String
},
installed(){this.setHours();
this.setMinutes();
this.initDateData();},
data() {
return{hour:[],
minute:[],
second:[],
timeList:[],
timeMltiSelectorValue:[0,0,0],
timeDesc:''
}
},
methods: {setHours(){for (let index = 0; index < 24; index++) {this.data.hour.push(index>9?index:'0'+index);
}
},
setMinutes(){for (let index = 0; index < 60; index++) {this.data.minute.push(index>9?index:'0'+index);
this.data.second.push(index>9?index:'0'+index);
}
},
initDateData(){
// 初始化设定以后工夫
this.data.timeMltiSelectorValue=[new Date().getHours(),new Date().getMinutes(),new Date().getSeconds()];
this.data.timeList=[this.data.hour,this.data.minute,this.data.second];
var picker = document.getElementById(this.props.pickerId);
picker.setData({data: this.data.timeList});
},
timeMultiSelectorChange(e){this.data.timeMltiSelectorValue=[e.detail.value[0],e.detail.value[1],e.detail.value[2]];
var hour = this.data.hour[e.detail.value[0]];
var minute = this.data.minute[e.detail.value[1]];
var second = this.data.second[e.detail.value[2]];
this.data.timeDesc = hour+':'+minute+':'+second;
this.fire('setDate', this.data.timeDesc);
},
}
}</script>
<style>
.picker {background-color: #ffffff;}
.picker-label{font-size: 18px;}</style>
组件应用
如果一个页面中，同一组件屡次应用，肯定要留神要把组件 ID 进行辨别。每个组件的 ID 通过以后页面传入组件。组件中通过 props 进行接管。
<template>
<scroll-view class="page">
<safe-area></safe-area>
<view class="item">
<text class="item-label"> 日程主题 </text>
<input class="item-input" placeholder="输出日程主题" v-model="title"/>
</view>
<view class="item">
<text class="item-label"> 日程简要 </text>
<textarea class="item-area" placeholder="输出日程简要内容" v-model="content"/>
</view>
