我是新的在nodejs,現在我有一個問題,我不能解決:在javascript/nodejs異步。我如何處理以下內容,以便將用戶名推送到數組中?
我已經試圖幫助自己與許多不同的功能,但沒有什麼工作對我來說...:/

function getCurrentBetInformations() {
connection.query('SELECT * FROM `BETS` WHERE BET_ACTIVE = "1" LIMIT 1', function(err, rowss, fields) {
if (err) logger.warn('MySQL Error: ' + err.stack);
betid = rowss[0].BET_ID;
betends = rowss[0].BET_END;
connection.query('SELECT * FROM `BETS_BID` WHERE BID_BET_ID=\'' + betid + '\'', function(err, betbids, fields) {
if (err) logger.warn('MySQL Error: ' + err.stack);
var betQuants = new Array();
var betIds = new Array();
var betUsernames = new Array();
var betDates = new Array();
var rowsAffected = betbids.length;
for(i=0; i < rowsAffected; i++) {
betQuants.push(betbids[i].BID_KEYS_COUNT);
betIds.push(betbids[i].BID_ID);
var betSender = betbids[i].BID_SENDER;
connection.query('SELECT `USER_NAME` FROM `USER` WHERE `USER_STEAMID` = \'' + betSender + '\' LIMIT 1', function(err, rows, fields) {
if (err) logger.warn('MySQL Error: ' + err.stack);
console.log(rows[0].USER_NAME);
addUsername(rows[0].USER_NAME);
});
function addUsername (currentUsername) {
betUsernames.push(currentUsername);
}
betDates.push(betbids[i].BID_TIME);
if(betUsernames.length === i) {
execSiteRef();
}
}
function execSiteRef() {
console.log(betUsernames);
sendUserSiteRefresh([betQuants, betIds, betUsernames, betDates], betends);
}
});
});
}
你得到的輸出是什麼?有什麼錯誤? – luksch
