Element 时间组件各种限制范围

一、时分秒

开始时间小于结束时间
结束时间大于开始时间

<el-time-picker 
    v-model="dataForm.startTime" 
    placeholder="请选择时间" 
    value-format='HH:mm:ss' 
    :picker-options="{
        selectableRange:`00:00:00 -${dataForm.endTime ? dataForm.endTime+':00' : '23:59:00'}`
    }"
></el-time-picker>
    -
<el-time-picker 
    v-model="dataForm.endTime" 
    placeholder="请选择时间" 
    value-format='HH:mm:ss' 
    :picker-options="{
        selectableRange:`${dataForm.startTime ? dataForm.startTime+':00' : '00:00:00'}-23:59:00`
    }"
></el-time-picker>

效果如下

二、年月日

直接上代码

<el-form-item label="日期" required>
    <el-col :span="11">
        <el-form-item prop="effectiveStartTime">
            <el-date-picker
                v-model="dataForm.effectiveStartTime"
                type="date"
                :picker-options="pickerOptions1"
                style="width: 100%;"
                placeholder="选择时间">
            </el-date-picker>
        </el-form-item>
    </el-col>
    <el-col style="text-align: center;" :span="2">-</el-col>
    <el-col :span="11">
        <el-form-item prop="effectiveEndTime">
            <el-date-picker
                v-model="dataForm.effectiveEndTime"
                type="date"
                :picker-options="pickerOptions2"
                style="width: 100%;"
                placeholder="选择时间">
            </el-date-picker>
        </el-form-item>
    </el-col>
</el-form-item>  

pickerOptions1:{ //起始日期——不可选
   disabledDate:(time)=>{
        if(this.dataForm.effectiveEndTime){
            return (time.getTime() < Date.now()-8.64e7) || (time.getTime() > new Date(this.dataForm.effectiveEndTime).getTime())
        }else{
            return time.getTime() < Date.now()-8.64e7;
        }
        
    }
},
pickerOptions2:{ //结束日期——不可选
    disabledDate:(time)=>{                        
        return time.getTime() < new Date(this.dataForm.effectiveStartTime).getTime();
    }
},

效果如下：
