Blocking full message in function node

Dashboard
1

Hello,

i would like to know how i can block a complete message in a function node.(Not with other nodes)
ATM i use: msg.payload = {};
but with this method i get only an empty payload.

Is there a easy way to block the full message?

Greetings

this will halt flow of message...

return null;

Remove the return msg altogether in the function node.

Mhmm i think i post my Code:

var Check = 0;

Check = global.get("boxlivescreen");

if (Check == 17) {
    msg.payload.MQTTBoxname = "W16";
    msg = msg.payload;
     node.status({fill:"green",shape:"dot",text:Check})
} else {
    msg.payload = {};
    node.status({fill:"red",shape:"dot",text:Check})
} 

return msg;

return null would be nice but with msg = null; the function node blocks everything, also when it should let pass.

You asked ...

I said...

If you want conditional blockage - you should ask.

Is this what you are trying to achieve...

var Check = 0;

Check = global.get("boxlivescreen");

if (Check == 17) {
    msg.payload.MQTTBoxname = "W16";
    msg = msg.payload;
    node.status({fill:"green",shape:"dot",text:Check})
} else {
    node.status({fill:"red",shape:"dot",text:Check})
    return null; //halt flow after updating status
} 

return msg;
