使用Javascript在双向链表中获取控制台错误

// 定义双向链表节点类
class Node {
  constructor(data) {
    this.data = data;
    this.prev = null;
    this.next = null;
  }
}

// 定义双向链表类
class DoublyLinkedList {
  constructor() {
    this.head = null;
    this.tail = null;
  }

  // 在链表末尾插入节点
  append(data) {
    const newNode = new Node(data);

    if (!this.head) {
      this.head = newNode;
      this.tail = newNode;
    } else {
      newNode.prev = this.tail;
      this.tail.next = newNode;
      this.tail = newNode;
    }
  }

  // 在链表任意位置插入节点
  insertAt(data, position) {
    const newNode = new Node(data);

    if (position === 0) {
      newNode.next = this.head;
      this.head.prev = newNode;
      this.head = newNode;
    } else {
      let current = this.head;
      let count = 0;

      while (count < position - 1) {
        current = current.next;
        count++;
      }

      newNode.prev = current;
      newNode.next = current.next;
      current.next.prev = newNode;
      current.next = newNode;
    }
  }

  // 获取链表中的控制台错误
  getConsoleErrors() {
    let current = this.head;
    let errors = [];

    while (current) {
      try {
        eval(current.data); // 执行可能会引发错误的代码
      } catch (error) {
        errors.push(error); // 将错误对象添加到数组中
      }

      current = current.next;
    }

    return errors;
  }
}

// 创建双向链表对象
const list = new DoublyLinkedList();

// 在链表中插入一些数据
list.append("console.log('Hello, World!');");
list.append("console.log('This is an error');"); // 这行代码会引发错误
list.append("console.log('No error here');");

// 获取链表中的控制台错误
const errors = list.getConsoleErrors();

// 打印错误信息
errors.forEach((error) => {
  console.error(error);
});
