计算jquery中的N个日期范围重叠

function checkDateRangesOverlap(dateRanges) {
  for (var i = 0; i < dateRanges.length; i++) {
    var range1 = dateRanges[i];
    var start1 = range1[0].getTime();
    var end1 = range1[1].getTime();
    
    for (var j = i + 1; j < dateRanges.length; j++) {
      var range2 = dateRanges[j];
      var start2 = range2[0].getTime();
      var end2 = range2[1].getTime();
      
      if (start1 <= end2 && end1 >= start2) {
        console.log("Date ranges overlap: " + range1 + " and " + range2);
        // 执行其他逻辑
      }
    }
  }
}

// 示例用法
var dateRanges = [
  [new Date("2022-01-01"), new Date("2022-01-10")],
  [new Date("2022-01-05"), new Date("2022-01-15")],
  [new Date("2022-01-12"), new Date("2022-01-20")]
];

checkDateRangesOverlap(dateRanges);
