APICloud AVM 封装日期和时间选择组件

因项目中很多表单要用到日期选择和时间选择的内容，所以基于picker封装了日期和时间选择的组件。

datePicker
组件内的年份是取得举例今年100年以内的年份，可根据时间需要进行扩容或缩减，月份是12个月固定的，每月的天数，根据所选年份和月份进行获取。默认设置当前日期。

100

101

102

timePicker

时、分、秒都是固定的，组件初始是默认的当前时间。

<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(){
                //初始化设定当前时间
                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>

组件使用

如果一个页面中，同一组件多次使用，一定要注意要把组件ID进行区分。每个组件的ID通过当前页面传入组件。组件中通过props进行接收。

<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="输入日程主题" v-model="title"/>
        </view>
        <view class="item">
            <text class="item-label">日程简要</text>
            <textarea  class="item-area" placeholder="输入日程简要内容" v-model="content"/>
