Question

我有一个这样的 React/javascript helper 类，但是由于某种原因，当我使用 Chrome 调试器时，它说 SET @Cur2 = CURSOR FOR SELECT title,receipt_date,decision_date From #tmpTable GROUP BY title,receipt_date,decision_date ORDER BY receipt_date OPEN @Cur2 FETCH NEXT FROM @Cur2 INTO @TITLE,@RECEIPT_DATE,@DECISION_DATE; WHILE @@FETCH_STATUS = 0 BEGIN select * from #tmpTable where receipt_date > @RECEIPT_DATE AND receipt_date < @DECISION_DATE FETCH NEXT FROM @Cur2 INTO @RECEIPT_DATE,@DECISION_DATE; END; 未定义，而 arrOfObj 工作正常。有谁知道原因吗？想了解我缺少的 javascript 细微差别。谢谢！

hi

export default class JSUtil {
  static average(arrOfObj, fn = null) {
    // for some reason JS debugger cant access arrOfObj, but works if I declare a const inside it
    const hi = arrOfObj
    debugger
  }
}

在 javascript 中，为什么我的静态方法中的参数在 Chrome 调试器中未定义？
