element week picker el-date-picker

2023.11.13 Today I learned that when using the element week selector, we will find that the default time selection is Sunday to the next Monday, as shown in the figure:

We need to change it to display Monday to Sunday, just add one line of code: picker-options

<el-date-picker
  type="week"
  placeholder="请选择周"
  :picker-options="{'firstDayOfWeek':1}"
  format="yyyy 第 WW 周"
/>
  

There will be a prompt that the parameter type does not match, but it will not be affected, as shown in the figure:

This allows you to freely select the date range.
