在Javascript中查找字符串中五个数字的最大序列

function findMaxNumberSequence(str) {
  let numberSequences = str.match(/\d+/g); // 使用正则表达式匹配数字序列
  let maxSequence = "";
  let maxValue = 0;

  for (let i = 0; i < numberSequences.length; i++) {
    if (numberSequences[i].length >= 5) {
      let sequence = numberSequences[i].substring(0, 5); // 取前五位数字序列
      let value = parseInt(sequence); // 转换为数值

      if (value > maxValue) {
        maxValue = value;
        maxSequence = sequence;
      }
    }
  }

  return maxSequence;
}

let str = "abc123456def78901ghi23456jklm";
let maxSequence = findMaxNumberSequence(str);
console.log("最大数字序列为：" + maxSequence);
