如何使用node.js在mongodb中根据条件更新数组中的对象

const MongoClient = require('mongodb').MongoClient;
const url = 'mongodb://localhost:27017'; // MongoDB连接URL
const dbName = 'your_database_name'; // 数据库名称

MongoClient.connect(url, function(err, client) {
  if (err) throw err;
  console.log('Connected successfully to MongoDB');

  const db = client.db(dbName);

  // 在这里执行更新操作
});

const collection = db.collection('your_collection_name'); // 集合名称

const filter = { /* 查询条件 */ };
const update = { $set: { /* 更新的字段 */ } };

collection.updateOne(filter, update, function(err, result) {
  if (err) throw err;
  console.log('Updated successfully');
  client.close();
});

const MongoClient = require('mongodb').MongoClient;
const url = 'mongodb://localhost:27017'; // MongoDB连接URL
const dbName = 'your_database_name'; // 数据库名称

MongoClient.connect(url, function(err, client) {
  if (err) throw err;
  console.log('Connected successfully to MongoDB');

  const db = client.db(dbName);
  const collection = db.collection('your_collection_name'); // 集合名称

  const filter = { /* 查询条件 */ };
  const update = { $set: { /* 更新的字段 */ } };

  collection.updateOne(filter, update, function(err, result) {
    if (err) throw err;
    console.log('Updated successfully');
    client.close();
  });
});
