[lalo]

Hi, I hope someone could help me with this I have this code so is kind of database of equations, and when I save a new one it appears on the dropdown, so my problem is that it appears as number in the dropdown but I need the equation. This is my code.

so in the pointed node I'm trying to chance the array to an object. Help please.

Not sure what your data is
in the previous function node you could do

msg.payload = Object.assign({}, arr);

what I want is something like this 2 dropdown

So you have the function to convert, i don't see what else you need.

Or are you looking for a JSONata expression to do your function in the change node?

edit/
I see you want bob to show in notification , is that correct

You can feed it an array no need for the object. Then the label and value would be the same

from info " msg.options containing an array. If just text then the value will be the same as the label, otherwise you can specify both by using an object of "label":"value" pairs :

[ "Choice 1", "Choice 2","

[{"id":"163ddde2.2ebeda","type":"function","z":"5e968879.8bee88","name":"transform data to correct format","func":"//as per info panel, the data needs to be formatted\n//as [ \"Choice 1\", \"Choice 2\", {\"Choice 3\":\"3\"} ]\n//and sent in msg.options.\nmsg.options = [];//create empty array\nfor(let i = 0; i < msg.payload.length; i++){\n    msg.options.push(msg.payload[i][0]);//add the opt to array    \n}\nreturn msg;","outputs":1,"noerr":0,"x":360,"y":120,"wires":[["8e1478f2.d4b1b"]]}]

So when I paste the equation I don't know why appears something in blank so I need some if about empty field or something.

[E1cid]

You will need to export and paste here the section of your flow that has the issue. Break it down to the least nodes possibe to create the error.

Also why multiple functon nodes in a row, would be better to combine them as each call to function node has a overhead.

[lalo]

Yeah about the multiple I'm not really good with that stuffs first I test it and then I try to clean my code.

The part is this one...

if you paste and the you delete what you put it makes an empty equation object. I can put like a button to send my paste equation and it will be send in to the payload?

[E1cid]

Not seeing any thing except a text input.

When i typed in text nothing happened. When looking at your code i noticed that it created multiple global context objects. You may want to look into that, as it may need tidying/removing entries.

[lalo]

please try to delete what you put and the paste again
