Adding JSON properties to a component via script?

[ericchesek]

Hello!

I'm stuck on what seems like a silly issue and I swear I've done it before.

I am adding a bunch of sliders to a panel in a for loop using Content.addKnob.
I want each of those knobs to have a custom JSON tag called "idNumber" or something.
Is there any way to add that "idNumber" JSON property and set it equal to the iterator of the for loop in script? I don't want to manually edit the JSON after the components are created.

THANKS!

@ericchesek you can't add custom properties to a component, either through scripting or by manual editing.

@ericchesek What is it you are trying to achieve? When you are creating the sliders in a loop, are you appending the index number to each in the name?
Here are some examples of indexing for the ID:

// a loop to create sliders
inline function createSliders(stringName, numOfSliders)
{
	local sliders = [];

	for (i = 0; i < numOfSliders; i++)
	{
		// this appends the index to the slider name: "stringName + i"
		local slider = Content.addKnob(stringName + i, 50 + i * 125, 50);
		// this stores the component object inside an array
		sliders[i] = slider;
		slider.set("style", "vertical");
	}
	return sliders;
}

// call the function to create the sliders
const mySliders = createSliders("MySlider", 4);
// a separate array for the names ("Id")
const mySlidersIdArray = mySliders.map(function(element){return element.getId();});

Console.print("mySlidersIdArray: " + trace(mySlidersIdArray));

So there are multiple ways to use an index as ID to associate with a component.

@VirtualVirgin Little unrelated tip of the day:

mySliders.map(function(element){return element.getId();});

can also be written as

mySliders.map(element => element.getId());

An arrow function expression is a compact alternative to a traditional function expression, with some semantic differences and deliberate limitations in usage:
