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。<template>

<picker class="picker" id={pickerId} mode="multiSelector" range-key="name" value={dateMltiSelectorValue} onchange={this.dateMultiSelectorChange} oncolumnchange={this.dateMultiSelectorColumnChange}>            
    <text class="picker-label">{dateDesc}</text>
</picker>

</template><script>

export default {
    name: 'datePicker',
    props:{
        label:String,
        pickerId:String
    },
    installed(){
        this.getYears();    
        this.initDateData();
    },
    data() {
        return{
            year:[],
            month:[1,2,3,4,5,6,7,8,9,10,11,12],
            day:[],
            yearNow:new Date().getFullYear(),
            dateMltiSelectorValue:[0,0,0],
            selectYear:new Date().getFullYear(),
            selectMoth:1,
            selectDay:1,
            dateList:[],
            dateDesc:''

        }
    },
    methods: {
        getYears(){
            this.data.year=[];//一个页面多次使用的情况 必须先清空 否则会出现各种问题
            for(i=0;i<100;i++){
                this.data.year.push(this.yearNow-i);
            }
        },
        initDateData(){
            //根据当前年月获取当月天数
            this.data.day=[];
            var days = new Date(new Date().getFullYear(), new Date().getMonth()+1, 0).getDate();
            console.log(days);
            for(i=1;i<=days;i++){

            this.data.dateList = [this.data.year,this.data.month,this.data.day];
            var picker = document.getElementById(this.props.pickerId);            
            picker.setData({
                data: this.data.dateList
            });
        },
        //根据年月获取天数
        setDays(){
            this.data.day=[];
            var days = new Date(this.data.selectYear, this.data.selectMoth, 0).getDate();
            for(i=1;i<=days;i++){

            var picker = document.getElementById(this.props.pickerId);
            picker.setData({

            });
        },
        dateMultiSelectorChange(e){
            this.data.dateMltiSelectorValue=[e.detail.value[0],e.detail.value[1],e.detail.value[2]];

            // var month = this.data.selectMoth>9?this.data.selectMoth:'0'+this.data.selectMoth;
            var month = this.data.month[e.detail.value[1]]>9?this.data.month[e.detail.value[1]]:'0'+this.data.month[e.detail.value[1]];
            var day = this.data.day[e.detail.value[2]]>9?this.data.day[e.detail.value[2]]:'0'+this.data.day[e.detail.value[2]];
            this.data.dateDesc = year+'-'+month+'-'+day;
            this.fire('setDate', this.data.dateDesc);
        },
        dateMultiSelectorColumnChange(e){

                this.setDays();        
            }
            else if(column==1){

                this.data.dateMltiSelectorValue[1]=e.detail.value;
                this.setDays();            
            }
        }
    }

</script><style>

        },
    }
}

</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>
