我正在尝试建立一个新项目。这将是一个网站的贸易机器人,现在将我收到的项目存储到我的数据库中,我希望每个项目都发送一些信息(名称,asseid,tradeid,...)。以下代码有效。
offers.on('receivedOfferChanged', function (offer, oldState) {
logger.info(offer.partner.getSteam3RenderedID() + " Offer #" + offer.id + " changed: " + TradeOfferManager.getStateName(oldState) + " -> " + TradeOfferManager.getStateName(offer.state));
// Alert us when we accept an offer
if (offer.state == TradeOfferManager.ETradeOfferState.Accepted) {
offer.getReceivedItems(function (err, items) {
if (err) {
logger.error("Couldn't get received items: " + err);
} else {
var names = items.map(function(item) {
return item.name;
});
var assetids = items.map(function(item) {
return item.assetid;
});
// Log a comma-separated list of items received
logger.info("Received: " + names + " " + assetids.join(', '));
}
});
}
});`
但问题是,有没有办法缩短以下代码:
var names = items.map(function(item) {
return item.name;
});
var assetids = items.map(function(item) {
return item.assetid;
});
所以它从数组中获取项目名称,资产ID,......并将它们存储在单独的变量中?
