我在做什么：
当新用户注册时，将生成一个个人钱包并将其存储在Mongo中。
最近，我们提出了一个请求，并从Mongo获取所有用户钱包地址，并将其存储在allDBWallets中。
每天都会生成一个新钱包，其地址存储在walletId中。
人们从他们生成的唯一地址向walletId汇款，我们开始记录和分析所有walletId交易记录。
// Check if a wallet has new transactions

希望我能找到可以帮助解释如何验证和提取发送到每日生成地址的用户地址和真实资金的人。
最佳答案
问题在于以下语句
if (entry.account == allDBWallets[i] && entry.account == walletId) {
条件2（entry.account == walletId）仅在
entry.account为2N1mqFS5nDJkPHTvKz1xBFs2LP8LwoKmcBH时为真，并且在这种情况下，条件1（entry.account == allDBWallets [i]）仅在allDBWallets数组具有2N1mqFS5nDJkPHTvKz1xBFs2LP8LwoKmcBH的条目。并且根据上述数据，这两个条件永远不会同时满足，因此不会获得理想的结果。
因此，您需要更正条件/逻辑以获得所需的输出。
可能的解决方案
allTransactions.forEach(function(transaction){
// Check whether there is an entry from any of the wallets in allDBWallets
var wallet = transaction.entries.find(function(entry){
return allDBWallets.indexOf(entry.account) > -1;
});
// If an entry exists, then find entries for walletId and paint
if(wallet) {
transaction.entries.forEach(function(entry){
if (entry.account == walletId) {
console.log(wallet.account, entry.value);
}
})
}
});
