控件做出判断控制
分析
给 el-date-picker
组件添加 picker-options
属性,并绑定对应数据 pickerOptions
- html
c
<el-form-item label="雨量年份:" prop="date">
<el-date-picker v-model="rainFall.form.date" type="year" format="yyyy" value-format="yyyy"
placeholder="请选择年份" :picker-options="pickerOptions" />
</el-form-item>
- js
c
data () {
return {
pickerOptions: {
disabledDate (time) {
return time.getTime() > Date.now() - 8.64e6
}
}
}
}
扩展
- 单个选择框的限制
- 设置选择今天及最近一年内的日期(包括今天)
c
data(){
return {
pickerOptions: {
disabledDate(time) {
let curDate = (new Date()).toString() // 当前时间戳转为字符串
let curDateYear = (new Date()).getFullYear() // 当前时间的年份
let oneYearAgoDate = curDate.replace(curDateYear,curDateYear-1)// 字符串年份替换为一年前
let oneYear = new Date(oneYearAgoDate).getTime() //一年前字符串转为时间戳
return time.getTime() > Date.now() || time.getTime() < oneYear;
}
}
}
}
- 设置选择今天及今天以后的日期
c
data (){
return {
pickerOptions0: {
disabledDate(time) {
return time.getTime() < Date.now() - 8.64e7;
}
}
}
}
- 设置选择今天及今天以前的日期
c
data (){
return {
pickerOptions0: {
disabledDate(time) {
return time.getTime() > Date.now() - 8.64e6
}
}
}
}
- 设置选择今天之后的日期(不能选择当天时间)
c
data (){
return {
pickerOptions0: {
disabledDate(time) {
return time.getTime() < Date.now();
}
}
}
}
- 设置选择今天之前的日期(不能选择当天)
c
data (){
return {
pickerOptions0: {
disabledDate(time) {
return time.getTime() > Date.now();
}
}
}
}
- 设置选择三个月之前到今天的日期
c
data (){
return {
pickerOptions0: {
disabledDate(time) {
let curDate = (new Date()).getTime();
let three = 90 * 24 * 3600 * 1000;
let threeMonths = curDate - three;
return time.getTime() > Date.now() || time.getTime() < threeMonths;;
}
}
}
}
- 两个输入框的限制
- 设置开始时间不能大于结束时间(且只能选择当前时间以前的日期)
c
data(){
return {
pickerOptions0: {
disabledDate: (time) => {
if (this.value2) {
return time.getTime() > Date.now() || time.getTime() > this.value2;
} else {
return time.getTime() > Date.now();
}
}
},
pickerOptions1: {
disabledDate: (time) => {
return time.getTime() < this.value1 || time.getTime() > Date.now();
}
}
}
}
- 设置开始时间不能大于结束时间(能选择所有日期)
c
data(){
return {
pickerOptions0: {
disabledDate: (time) => {
if (this.value2) {
return time.getTime() > this.searchForm.endTime
}
}
},
pickerOptions1: {
disabledDate: (time) => {
return time.getTime() < this.searchForm.startTime
}
}
}
}
