sleep / wait function in javascript

[esc...@missionroom.nl]

Trying to show a message for 2 seconds and then show other message.

Part of the script is this

        if ( code == 1233 ){

           msg.code = "BAM!";

       

           msg.code = "enter code";

           

       }

I tried :

function sleep (time) {

 return new Promise((resolve) => setTimeout(resolve, time));

}

------

        if ( code == 1233 ){

           msg.code = "BAM!";

           sleep(500).then(() => {

           msg.code = "plop!";

           });

       }

but that did nothing....

what am i doing wrong?

will the trigger node not do what you want ?

[Nick O'Leary]

Is this code in a Function node or a custom node you are writing?

It's hard to help with so little information about where this code is being used.

after entering the code it give a success or fail message

i want to show the result for only 2 seconds and then become empty again

[Dave C-J]

again.. what is wrong with the trigger node ?

[esc...@missionroom.nl]

The code is doing the job it needs to do.

When entering a wrong code if gives false

But what i am trying to create is that the message false is only visible for 2 seconds.

I tried this with several delay and sleep functions but that didnt work out

the code I sent shows the message to 2 seconds (good or error) then goes blank... is that not what is wanted ?

[esc...@missionroom.nl]

See the node-red flow at the bottom of Dave's Email that starts "again.. what is wrong with the trigger node ?"

You can import this into node-red by going Import > Clipboard

[esc...@missionroom.nl]

O it had some more mistakes, but now it is functioning with the code below.

Sorry...

But then my wish is that the result is displayed for 2 seconds and then blank
