Executing JS script in seperate layout

I asked this in discord but did not get an answer. How can I execute a jsON script on seperate layout (and not first layout only), the MAIN script just executes everything in the beginning. I dont want to use "IMPORT FOR EVENTS" either. Is this not possible?

It depends on what you want to achieve. You can embed a procedure in a function to be performed only when necessary, when you decide

For example I wrote this C3P file tom demonstrate https://we.tl/t-afPO2wmT0t

It will work if it is started from Layout 1, because main is executed and printer.js works fine. But if you start from START layout which automatically goes to --> LAYOUT 1 , it gives an error because the information on main.js is lost

I have tried the impport and export but couldnt get it to work

Problem is when you start from the "Start" layout, the text instance doesn't exist yet, so "getFirstInstance()" returns null. When you try to use your global variable "statusTextInstance", it then fails from a null reference error.

What you could do is simply set the global during the start of the "Print" layout, or using the "on created" trigger of the text instance.

Oh I understand, but still can not figure out how to do it. Can you help me out?

Move the line

> 	globalThis.statusTextInstance = runtime.objects.txtOutput.getFirstInstance();

to the ePrinter event sheet. Either before the other line in the "Start of layout" trigger, or simply use the "On created" trigger of the text object.

Wow this, worked. So is this the only way, can not do it solely on js script?

Thx a lot, so I see you have also used const instance = runtime.objects.othersOutput.getFirstPickedInstance(); within event sheet. I guess there is no other way right? Executing the whole thing through JS scripts only does not look possible.

I get this error --> printer.js:8 Uncaught (in promise) ReferenceError: runtime is not defined

Can you test it out when you are infront of your computer? Thank you very much, this has driven me mad

Use this

export function printTextToOutput() {
 const instance=g_runtime.objects.textOutput.getFirstInstance();
instance.text = text;
}

runOnStartup(async runtime => {	globalThis.g_runtime = runtime; });
