项目搭建用的vant组件库,但是vant官网上DatetimePicker
时间组件van-datetime-picker
没有单独显示年份的组件,下面给大家介绍一下改造后的代码!
template代码
<van-cell-group> <van-field style="text-align:center" readonly clickable placeholder="请选择年份" :value="dateValue" @click="showPicker = true" /> <van-popup v-model="showPicker" round position="bottom"> <van-picker title="请选择年份" show-toolbar :columns="columns" :default-index="select" @confirm="yearConfirm" @cancel="cancel" /> </van-popup> </van-cell-group>
script代码
data() { return { dateValue: '', showPicker: false, select: null, columns: [] } }, created() { this.getCurrentYear() this.getYearData() }, methods: { formatDates(date) { return `${date.getFullYear()}-${date.getMonth() + 1}-${date.getDate()}` }, //获取默认最新时间 getCurrentYear() { var nowTime = new Date() let year = nowTime.getFullYear() let month = nowTime.getMonth() let day = nowTime.getDate() var dateValue = '' dateValue = this.formatDates(new Date(year, month, day)) this.dateValue = dateValue.slice(0, 4) this.signs(this.dateValue) }, //年选择器 yearConfirm(value) { this.dateValue = value.toString() this.signs(this.dateValue) this.showPicker = false }, //年数据 getYearData() { var nowTime = new Date(this.dateValue) let year = nowTime.getFullYear() let month = nowTime.getMonth() let day = nowTime.getDate() for (let i = 1901; i < 2099; i++) { this.columns.push(i) } var years = this.formatDates(new Date(year, month, day)) var Year = years.slice(0, 4) this.select = this.columns.indexOf(Number(Year)) }, //点击取消按钮时触发的事件 cancel() { this.showPicker = false } }
el-table利用:row-style="rowClass"设置指定行变色
