Help with `text input` node

I'm working on a small project just to keep myself busy.

I have a text input node.

Normally it is disabled.

When enabled (for a short time) the user enters text.
After that time the node is disabled, and the text entered is retained. :frowning:

How can I wipe the text?
If I send a msg.payload == " " it messes up the next time the node is enabled as it has (remembers) the space sent previously.

Thanks in advance.

Have you tried

msg.payload = ""

How do I do that in a change node?

I fear that if I make msg.payload text and put "", I will get just that.


So I set it with J: (expression) - yes?

In the change node, leave the value blank

and it is easy enough to test...

Silly me. I didn't think of that.
