javascript - TypeError:无法读取不确定的tempObj ['TigerNo'] = this.getDefault(sportsRecord).TigerNo的属性'TigerNo'

我是js的新手。
我在sportsRecord中获取值，但无法在tempObj['TigerNo']中分配值。
当我分配时，我得到了这个错误--
类型错误：无法读取未定义的属性“tigerno”
tempobj['tigerno']=this.getdefault（运动记录）.tigerno；
我在下面提供相关代码和GIST中的全部代码
你们能告诉我怎么修理吗？
在下面提供我的代码

最佳答案

变量：

sportsRecord.isDefault

设置不正确。
所以，
this.getDefault(sportsRecord)
退货

'undefined'

呼叫前设置sportsRecord.isDefault
