具体使用

<script setup>
import { getDateRange, getCurrentDay, getCurrentDate  } from "@/api/date.js";

const container = ref(null);
const handleScroll = () => {
 const assd1=   getDateRange()
 console.log('获取近期日期数组',assd1);
 const assd2=   getCurrentDay()
 console.log('获取今日日期',assd2);
 const assd3=   getCurrentDate()
 console.log('获取当前日期时间',assd3);
}
handleScroll()
