在Node-Red中工作。我可以跨节点使用常规的全局变量，并且流程没有问题。但是，想使用全局数组变量。
方法A-所需的功能我一次读取16个数据点（类型=双精度），并希望它们的索引为0-15，那么下一个节点将更新索引16-31；然后是最后两个节点中的32-45和46-64。
但是，红色节点不允许从索引16开始的第二个节点更新数组。我收到“ TypeError：无法读取未定义的属性'indexOf'”错误。
代替方法A，我可以有四个不同的16索引全局数组。但是，访问它们会导致不稳定的结果。尝试访问index [n]会从其他索引中返回值-即global.get("variable"[0])返回variable[10]并global.get("variable"[1])从中返回值variable[27]。
这描述了问题 -https://www.youtube.com/watch?v=cF1bz8bEozI
这是我的示例流程：
