使用 Higcharts 访问数组时出现问题，我如何访问 x 位置？

Question

我正在尝试使用 Highcharts 访问 UserOptions 传递的数组位置。

Series declaration, where i declare the array

Implementation

问题是，当我尝试访问此数组的元素时，它没有显示。

刚看到：

Accessing array

但是，当我直接访问它并使用 console.log() 打印它时，会显示此值。

console.log(a.series[1].userOptions.cuotasPendientes[5]);

Accessing directly

谢谢大家。

代码：

console.log(a.series[1].userOptions.cuotasPendientes[5]);

Answer 1

你可以直接调用它或以这种方式循环遍历 CuotasPendientes 你的值并且不要忘记检查 CuotasPendientes 值如果它为空循环将不会处理（我已经添加了空检查） .

console.log(a.series[1].CuotasPendientes[0])

for(let i = 0 ; i < a.series.length; i++){
  if (a.series[i].CuotasPendientes != null) {
    for (x of a.series[i].CuotasPendientes) {
      console.log(x)
    }
  }
}

希望对您有所帮助

Answer 2

我尝试使用格式化程序，它有效，我也发现了访问方式。

而不是使用 point.series.cuotasPendientes[2]，我们必须使用point.series.cuotasPendientes.2
