Re: Parsing a string

 

¿ªÔÆÌåÓý

BTW, this can all be done in one function node using Mick¡¯s example then looking for each msg.out to either be 0 or 1 and setting msg.out to false or true. (if/else)

?

More than one way to get to the desired output.

Here is a function to split the input and output a msg for each bit.? ?I used a string of 10000000 as the inject

?

?

The output gives you the msg.payload and msg.topic

?

Here is the function.

?

var output = msg.payload.split("");
msg.out0 = parseInt(output[0]);
msg.out1 = parseInt(output[1]);
msg.out2 = parseInt(output[2]);
msg.out3 = parseInt(output[3]);
msg.out4 = parseInt(output[4]);
msg.out5 = parseInt(output[5]);
msg.out6 = parseInt(output[6]);
msg.out7 = parseInt(output[6]);
msg.out8 = parseInt(output[7]);
msg.out9 = parseInt(output[8]);
msg1 = {topic: 'Bit 1',payload:msg.out0};
msg2 = {topic: 'Bit 2',payload:msg.out1};
msg3 = {topic: 'Bit 3',payload:msg.out2};
msg4 = {topic: 'Bit 4',payload:msg.out3};
msg5 = {topic: 'Bit 5',payload:msg.out4};
msg6 = {topic: 'Bit 6',payload:msg.out5};
msg7 = {topic: 'Bit 7',payload:msg.out6};
msg8 = {topci: 'Bit 8',payload:msg.out7};
msg9 = {topic: 'Bit 9',payload:msg.out8};

node.send(msg1);
node.send(msg2);
node.send(msg3);
node.send(msg4);
node.send(msg5);
node.send(msg6);
node.send(msg7);
node.send(msg8);
node.send(msg9);

return;

You could then run this into a switch node for further?processing or just modify it by creating a var instead of msg and then process it in the function.?

Split/Switch is the way to go. Easy.

Hi Neal

Yes, that is the status of 8 relays that I need to break out so I can build an LED panel (so to speak)

I don't have the actual answer, but I *think* I understand how to describe what you want:

?

Given a binary string of 1's and 0's such as, for example, 10010110 , parse out each digit position, and assign?each digit to
a separate boolean variable name set to 1 or 0.? ? Is that what?you're looking for?

Hi All

I have a string I need to parse of 8 binary values being returned from a relay board

10000000

What is the best way to parse out the status of each of these relays???

?

I looked at 'string' but I can't see a method that allows me to pull the boolean out 1 at a time.

?

thoughts?
