Sending multiple msg from function node

[RedRobin132]

Hello!
In a function node, i get (as input) an array of multiple objects. Now i want to extract one string from each object (all objects are built the same) and send each string separately over one node-output.
Is that possible?

Thanks in advance

Are you wanting to send all the messages out the same output?

If yes:

You do a node.send() command, rather than the return msg command.

So...

You would get the incoming message, split it up into the required bits and then node.send() for each part.

That is a real basic overview but I hope it helps.

Dunno how good this example is, but.....

A low-code approach without using a function node:

[{"id":"1c22da8356c1b02b","type":"inject","z":"5c74cb9708ad35f2","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":300,"y":220,"wires":[["cb5500dc47be6855"]]},{"id":"cb5500dc47be6855","type":"change","z":"5c74cb9708ad35f2","name":"Input data","rules":[{"t":"set","p":"payload","pt":"msg","to":"[{\"artist\":\"Poussin\",\"work\":\"Et in Arcadia Ego\"},{\"artist\":\"Van Eyck\",\"work\":\"St Barbara\"},{\"artist\":\"Rembrandt\",\"work\":\"An Elephant\"}]","tot":"json"}],"action":"","property":"","from":"","to":"","reg":false,"x":440,"y":220,"wires":[["605df9858753148e","bc24dc603eef50db"]]},{"id":"605df9858753148e","type":"change","z":"5c74cb9708ad35f2","name":"\"work\" property of each array element","rules":[{"t":"set","p":"payload","pt":"msg","to":"payload.work","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":430,"y":280,"wires":[["b9fe67ee07bd5811"]]},{"id":"e96ea5c80297c7da","type":"debug","z":"5c74cb9708ad35f2","name":"Output","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","statusVal":"","statusType":"auto","x":790,"y":280,"wires":[]},{"id":"b9fe67ee07bd5811","type":"split","z":"5c74cb9708ad35f2","name":"","splt":"\\n","spltType":"str","arraySplt":1,"arraySpltType":"len","stream":false,"addname":"","x":650,"y":280,"wires":[["e96ea5c80297c7da"]]},{"id":"bc24dc603eef50db","type":"debug","z":"5c74cb9708ad35f2","name":"Input data","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","statusVal":"","statusType":"auto","x":780,"y":220,"wires":[]}]
