Trivial text formatting (new line) in a function node

[Bobo]

I have been trying to format some text by creating a new line in a function node, but no luck. I have tried just about every combo of \n, \\n, etc I can think of.

Can someone please explain my error?

Thanks

if (ptime != "false") {msg.payload = msg.payload + "\n - Last ping time was on " +
  new Date().toString();}

In what way does that not work?

\n has no effect.
\\n causes one \n to appear in the text.

Should also say this is for output to a dashboard text node, which is where I want the new line to appear.

[Colin Law]

When you say \n has no effect I presume you mean that when it is
displayed you see no new line. Putting the \n in the text *does* have
the effect of putting a newline in the text. I suspect that your
problem is that in html a newline is effectively ignored. If you want
to see a newline in the text you need <br> in the html text. However
if you just put this in the text I suspect the text node will escape
the string and show <br>. I will have to leave it to others to tell
you how to get round this problem

Where are you trying to display the line of text? In a UI? Are you sending it to an email? Twitter? In a debug node?

a little more about what you are trying to do and the flow would be helpful.

As previously stated, this is for output to a dashboard text node, which is where I want the new line to appear.

So input is a ping node --> function node --> text node. That is it, nothing complicated at all.

Thanks

[Colin Law]

Looking at the info for the text node it says it can contain valid
html, so this should work

msg.payload = msg.payload + "<br> - Last ping time was on " + new
Date().toString();

Colin, it does indeed. Thank you for your assistance.

Bobo

Glad to be of help. Please make sure you understand why that works.

First off, RTFM and then read https://www.w3schools.com/tags/tag_br.asp

Peace out.

[Colin Law]

Do you mean *I* should RTFM?

Only if you think you should :-)

I was referring to myself. Sometimes its easy to fall into the trap of ignoring what is right under your nose, as I did. It states quite clearly in the text node info panel that it accepts html. If I had read that first I wouldn't have wasted your time.

Thanks again.

[Colin Law]

OK, understood.
