带数组的节点红色过滤器数组

Question

我有这个节点红色测试设置，我想用数组过滤对象数组。问题是，测试设置 returns 原始数组的未过滤副本。我已经发布了另一个关于此的问题，其中的评论表明我做的一切都是正确的。这个问题被主持人关闭了。但是我的问题还是没有解决。

谁能告诉我哪里错了？

输入数组payload是一个元素数组：

[{"altname":"melon"},{"altname":"cherry"},{"altname":"banana"}]

过滤器数组 exclude 有 2 个元素：

[["melon"],["banana"]]

我希望输出数组只有 1 个元素：

[{"altname":"cherry"}]

我的设置：

[{"id":"b4b2e91f.8e4368","type":"inject","z":"42edc0b9.7ba91","name":"","props":[{"p":"payload"},{"p":"exclude","v":"[[\"melon\"],[\"banana\"]]","vt":"json"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"[{\"altname\":\"melon\"},{\"altname\":\"cherry\"},{\"altname\":\"banana\"}]","payloadType":"json","x":1650,"y":320,"wires":[["3fbdbc18.951c94"]]},{"id":"3fbdbc18.951c94","type":"function","z":"42edc0b9.7ba91","name":"cycle counter","func":"\n\nmsg.payload = msg.payload.filter(el => !msg.exclude.includes(el.altname));\n\nnode.warn(msg.payload);\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[],"x":1810,"y":320,"wires":[["ab67374c.c64458"]]},{"id":"ab67374c.c64458","type":"debug","z":"42edc0b9.7ba91","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":2040,"y":300,"wires":[]}]

除了下面的评论之外，还有我的设置说明：

注入节点：

msg.payload = [{"altname":"melon"},{"altname":"cherry"},{"altname":"banana"}]
msg.exclude = [["melon"],["banana"]]

功能节点：

msg.payload = msg.payload.filter(el => !msg.exclude.includes(el.altname));
node.warn(msg.payload);
return msg;

Answer 1

问题是您的排除数组是二维数组，而不是简单的单深度数组。

msg.exclude 应该是：

["melon","banana"]

对于代码，您必须正确运行。
