template部分：
<el-form-item label="选择时间"><el-date-pickerv-model="bodyCount.date"type="daterange"range-separator="至"start-placeholder="开始时间"end-placeholder="结束时间"format="yyyy-MM-dd"value-format="timestamp":picker-options="pickerOptions"></el-date-picker></el-form-item>
script部分：
......data(){return{timeOptionRange: '',pickerOptions: {onPick:time => {//当第一时间选中才设置禁用if (time.minDate && !time.maxDate) {this.timeOptionRange = time.minDate;}if (time.maxDate) {this.timeOptionRange = null;}},disabledDate:time => {let timeOptionRange = this.timeOptionRange;let secondNum = 60 * 60 * 24 * 7 * 1000;if (timeOptionRange) {if((timeOptionRange.getTime()+secondNum)>(Date.now() - 8.64e6)){return time.getTime() > Date.now() - 8.64e6 || time.getTime() < timeOptionRange.getTime() - secondNum;}return time.getTime() > timeOptionRange.getTime() + secondNum || time.getTime() < timeOptionRange.getTime() - secondNum;}}},}}
