**思路：通过日期控件的v-model赋默认值即可**

**第一步， 引入日期控件**

<el-form-item label="日期">
        <el-date-picker
            v-model="visitDate"
            type="daterange"
            @change="getTime"
            format="yyyy-MM-dd"
            value-format="yyyy-MM-dd"
            range-separator="至"
            start-placeholder="开始日期"
            end-placeholder="结束日期">
        </el-date-picker>
    </el-form-item>

**第二步， data中visitData存成数组**  
**第三步， 页面挂载时给visitData赋值即可**

mounted () {
        let nowDate = new Date();
        let year = nowDate.getFullYear();
        let month = nowDate.getMonth() + 1;
        let day = nowDate.getDate();
        let endTime = `${year}-${month}-${day}`;
        this.nowTime = endTime; // 当前的时间点
        let befDate = new Date(nowDate.getTime() - 7 * 24 * 3600 * 1000);
        let byear = befDate.getFullYear();
        let bmonth = befDate.getMonth() + 1;
        let bday = befDate.getDate();
        let startTime = `${byear}-${bmonth}-${bday}`;
        this.weekBeforeTime = startTime; // 向前推迟一周的时间点
    
        // 默认日期赋值
        this.visitDate = [new Date(byear + ', ' + bmonth + ', ' + bday), new Date(year + ', ' + month + ', ' + day)];
        console.log('填充默认日期');
        console.log(byear + ', ' + bmonth + ', ' + bday);
        console.log(year + ', ' + month + ', ' + day);
        console.log(this.visitDate);
        console.log('填充默认日期尾部');
    }

**最后页面初始化时效果图如下:**

**感受：原作者通过将两个时间放在了一起，其实可以将前后的数据分别显示在两个DataPicker控件中，这样子更加清晰。**
