JavaScript满足条件移除数组元素及日期对比状态验证问题

日期对比与状态验证规则 #

• 对比两个对象数组array1与array2：
  • 若array1元素的开始、结束日期均在array2某元素的日期范围内，验证该array1元素的status为"overlap"；
  • 若array1元素的开始、结束日期均在array2某元素的日期范围外，验证其status为"ready"；
  • 若array1元素与array2某元素的开始、结束日期完全匹配，验证其status为"match"；
    目前已实现同月份日期匹配对比逻辑。
• 筛选出array1中与array2无对应月份的元素组成新数组array3，并验证array3中所有元素的status为"ready"；
• 移除array1中满足上述任一条件的元素，返回新数组。

当前实现代码 #

对比函数代码 #

function compareTwoArrayOfObjects(array1, array2) {
  array2.map(element => {
    const start2 = new Date(element.start_date);
    const end2 = new Date(element.end_date);

    const start2Month = start2.getMonth();
    const end2Month = end2.getFullYear();

    console.log("####################################")
    return array1.map(elm_arr1 => {
      const start1 = new Date(elm_arr1.start_date);
      const end1 = new Date(elm_arr1.end_date);
      let status;

      const start1Month = start1.getMonth();
      const end1Month = end1.getFullYear();

      if (start1.getTime() === start2.getTime() && end1.getTime() === end2.getTime() && ((start1Month === start2Month) || (end1Month === start2Month))) {
        console.log("**************")
        status = "match";
        console.log(start1, end1)
        console.log(start2, end2)
        console.log(start1Month, start2Month)
        console.log(elm_arr1.status)
        //expect(elm_arr1.status).toMatch("match");
        console.log("**************")
      } else if (((start1Month === start2Month) || (end1Month === start2Month)) && ((start1 > start2 && start1 < end2) || (end1 > start2 && end1 < end2) || (start2 > start1 && start2 < end1) || (end2 > start1 && end2 < end1))) {
        status = "overlap";
        console.log("**************")
        console.log(start1, end1)
        console.log(start2, end2)
        console.log(start1Month, start2Month)
        console.log(elm_arr1.status)
        // expect(elm_arr1.status).toMatch("overlap");
        console.log("**************")
      } else if (((start1Month === start2Month) || (end1Month === start2Month)) && ((start1 < start2 && end1 < start2) || (start1 > end2 && end1 > end2))) {
        status = "ready";
        console.log("**************")
        console.log(start1, end1)
        console.log(start2, end2)
        console.log(start1Month, start2Month)
        console.log(elm_arr1.status)
        //expect(elm_arr1.status).toMatch("ready");
        console.log("**************")
      }
    });
  });
}

const result = compareTwoArrayOfObjects(array1, array2);

测试数据代码 #

<script>
  let array1 = [{
      start_date: "Dec 01 2022",
      end_date: "Dec 07 2022",
      status: "ready"
    },
    {
      start_date: "Dec 04 2022",
      end_date: "Dec 10 2022",
      status: "ready"
    },
    {
      start_date: "Dec 15 2022",
      end_date: "Dec 21 2022",
      status: "overlap"
    },

    {
      start_date: "Dec 18 2022",
      end_date: "Dec 24 2022",
      status: "overlap"
    },

    {
      start_date: "Dec 12 2022",
      end_date: "Dec 28 2022",
      status: "overlap"
    },
    {
      start_date: "Dec 25 2022",
      end_date: "Dec 31 2022",
      status: "overlap"
    },
    {
      start_date: "Nov 22 2022",
      end_date: "Nov 28 2022",
      status: "match"
    },
    {

    {
      start_date: "Feb 16 20226",
      end_date: "Feb 22 2022",
