Javascript未捕获类型错误：无法读取未定义的属性

我正试图以一种方式操纵我的响应数据，使每组数据组成为一个数组。 所以我做了一个循环，每年检查每个对应的关联值，分组如下：

vm['years'][0] = (Array(12)),

vm['years'][1] = (Array(12)),

vm['years'][2] = (Array(8)),

vm['years'][3] = (Array(5)),

...

这就是我的剧本：

<script type="text/javascript">

响应有34行，但当我点击

response[35]时，我得到：

未捕获的TypeError:无法读取未定义的属性“year”

我试图在“while”之前做一个“if”语句，比如
response[x]。year==undefined
和
response[x]。year==null
和
response[x]。hasOwnProperty（year）
，但没有成功。
我找不到更好的方法来获得我想要的结果，我将非常感谢任何有助于建立一致逻辑的帮助。
错误源于
响应[x]
是
未定义的
。使用
响应[x].year
就像访问
未定义。year
是一个错误，因此使用：

if ( response[x].year === undefined ) 

由于您仍在尝试访问
response[x].year
，因此作为一个防护也会导致相同的错误。您应该将其用作防护：

if ( response[x] === undefined ) 

错误源于
响应[x]
是
未定义的。使用
响应[x].year
就像访问
未定义。year
是一个错误，因此使用：

if ( response[x].year === undefined ) 

由于您仍在尝试访问
response[x].year
，因此作为一个防护也会导致相同的错误。您应该将其用作防护：

if ( response[x] === undefined ) 

就我个人而言，我会这样做：
