Javascript 为什么我的递归函数不能正确循环使用JSON？
最近编辑为较短 在这里问这个问题可能不太可能，但我需要一个我创建的递归函数的帮助。它没有从JSON中获取我想要的值。基本上，我希望得到所有“流”对象ID，它们的“类型”为“标准”或“块”。这些对象可以嵌套在父“Flow”对象下的多个“Flow”对象中，这就是为什么我需要一个递归方法来搜索所有这些对象。我创建了一个代码笔，因此您可以在这里看到我得到的结果： 该函数位于底部，名为“GroupRecursion”，我将JSON“Payload”作为参数传递给它 在我的数组ArrayOfBlockId中，我只得到了大约3个ID（字符串），我应该正好得到4个字符串，因为有多少对象具有“Type”=“Standard”或“Block”。谢谢你的时间，如果这不是这个地方，让我知道Javascript 为什么我的递归函数不能正确循环使用JSON？,javascript,json,Javascript,Json,最近编辑为较短 在这里问这个问题可能不太可能，但我需要一个我创建的递归函数的帮助。它没有从JSON中获取我想要的值。基本上，我希望得到所有“流”对象ID，它们的“类型”为“标准”或“块”。这些对象可以嵌套在父“Flow”对象下的多个“Flow”对象中，这就是为什么我需要一个递归方法来搜索所有这些对象。我创建了一个代码笔，因此您可以在这里看到我得到的结果： 该函数位于底部，名为“GroupRecursion”，我将JSON“Payload”作为参数传递给它 在我的数组ArrayOfBlockId
