＜el-date-picker＞ 设置可选时间的上下限

You can use the picker-options attribute to set the minimum and maximum allowed dates for an el-date-picker. Here's an example:

<template>
  <el-date-picker
    v-model="selectedDate"
    :picker-options="pickerOptions"
    type="date"
    placeholder="Select date"
  ></el-date-picker>
</template>

<script>
export default {
  data() {
    return {
        selectedDate: null,
        pickerOptions: {
          disabledDate(time) {
            const minDate = new Date();
            minDate.setHours(0, 0, 0, 0); // set minimum date to start of today
            const maxDate = new Date();
            maxDate.setDate(maxDate.getDate() + 7); // set maximum date to 7 days from today's date
            return time.getTime() < minDate.getTime() || time.getTime() > maxDate.getTime();
          }
        }
    };
  }
};
</script>

In the example above, the pickerOptions object is used to set a disabledDate function which disables all dates before the start of today (minDate) and after 7 days from today's date (maxDate). You can adjust these values to fit your specific needs.
