1.ELEMENT UI 日期選擇器禁止跨年選擇(禁止跨月同理)
未日期選擇時:
選擇第一個日期之後其他年份的日期無法選擇,第二個日期只能從第一個日期年份中選擇效果圖:
<el-date-picker v-model="selectedDateValue" value-format="yyyy-MM-dd"
format="yyyy-MM-dd" type="daterange" :picker-options="pickerOptions0"
range-separator="至" ></el-date-picker>
export default {
data() {
return {
selectDate: null,
selectedDateValue: null, //時間區間
pickerOptions0: {
disabledDate: time => {
if (this.selectDate == null) {
return false
} else {
return (this.selectDate.getFullYear() != time.getFullYear())
}
},
onPick: date => {
// 如果只選擇一個則保存至selectDate 否則selectDate 爲空
if (date.minDate && !date.maxDate) {
this.selectDate = date.minDate
} else {
this.selectDate = null
}
}
},
};
},
}
2.ElementUI日期組件el-date-picker設置不能跨年/跨月/跨周
<el-date-picker
v-model="groupSearchTime"
type="daterange"
range-separator="至"
start-placeholder="開始日期"
end-placeholder="結束日期"
value-format="yyyy-MM-dd"
style="width: 482px;line-height: 24px"
:picker-options="pickerOptions"
@change="getSearchTime">
</el-date-picker>
data中的代碼:通過pickerOptions字段來控制時間選擇器組件的禁用與否,因此關鍵點就在於得到合法時間的前後時間
data() {
return {
groupSearchTime: [],
choiceDate: '',
pickerOptions: {
onPick: ({ maxDate, minDate }) => {
this.choiceDate = minDate.getTime()
if (maxDate) {
this.choiceDate = ''
}
},
disabledDate: (time) => {
const self = this
if (self.choiceDate) {
const selectDate = new Date(self.choiceDate)
const nowYear = selectDate.getFullYear() // 當前年
const nowMonth = selectDate.getMonth() // 當前月
const nowDate = selectDate.getDate() // 當前幾號
const nowDay = selectDate.getDay() // 當前星期幾
// 本月的開始時間
const monthStartDate = new Date(nowYear, nowMonth, 1).getTime()
// 本月的結束時間
const monthEndDate = new Date(nowYear, nowMonth + 1, 0).getTime()
// 本年的開始時間
const yearStartDate = new Date(nowYear, 0, 1).getTime()
// 本年的結束時間
const yearEndDate = new Date(nowYear, 12, 0).getTime()
// 本週的開始時間,本週的結束時間
const weekStartDate = new Date(nowYear, nowMonth, nowDate - nowDay + 1)
const weekEndDate = new Date(nowYear, nowMonth, nowDate + (7 - nowDay))
// 前後三天
const tStartDate = new Date(nowYear, nowMonth, nowDate - 2)
const tEndDate = new Date(nowYear, nowMonth, nowDate + 2)
// 此處以不能跨月做示範
return time.getTime() < monthStartDate || time.getTime() > monthEndDate
}
}
}
}
}
