Javascript 循环输出[对象，对象，对象]
最近我参加了一些在线课程，试图了解编程的基础知识，并逐渐尝试增加我所学内容的复杂性。然而，我似乎无法控制循环的输出，我要么得到最后一个值，要么得到[object，object，object，object，object] 任何帮助都将不胜感激，我相信这是非常简单的，但我已经尝试了很多次了，到目前为止都没有运气Javascript 循环输出[对象，对象，对象],javascript,json,loops,for-loop,Javascript,Json,Loops,For Loop,最近我参加了一些在线课程，试图了解编程的基础知识，并逐渐尝试增加我所学内容的复杂性。然而，我似乎无法控制循环的输出，我要么得到最后一个值，要么得到[object，object，object，object，object] 任何帮助都将不胜感激，我相信这是非常简单的，但我已经尝试了很多次了，到目前为止都没有运气 { "years": [ { "id": "1", "year": "2015", "total": "55045", "poin

我希望有人能帮助控制循环的输出。您没有显示任何代码，但我可以猜您的问题是JavaScript中的典型问题： 看看neurosnap的答案 在CoffeeScript中更简单：
for filename in list
do (filename) ->
fs.readFile filename, (err, contents) ->
compile filename, contents.toString()
基本上，在JavaScript to循环中，for循环中需要一个lambda/iLife来避免问题。您想确切知道什么？什么循环？所有这些都是一个对象，如果没有看到您的实际代码，几乎不可能猜出原因是什么。如果您需要帮助处理您遇到问题的循环，您必须向我们展示用于循环的代码。这里显示的只是一个Javascript对象定义。如果您不通过包含实际循环代码来澄清，您的问题将很快结束。
