Array Ports

This page will explain how to create an input and output port of the type 'Array'


Click this link to see an example of all port types and code examples

A Javascript array can contain either simple values, arrays or objects

Arrays are used to store multiple values in a single variable.

E.g. [1, 2, 3], [[1, 2], [3, 4]], [{"one": 2}, {"three": 4}]

If you click the op and then the inspect icon Button you can see the array contents


//strict mode allows us to write cleaner code
"use strict";

//Create a input port of the type Array
const inArr   = op.inArray("Array in");

//Create a output port of the type Array
const outArray  = op.outArray("Array out");

//cache for errors
var showingError = false;

//when array in changes call the function update
inArr.onChange = update;

function update()
    //create an array called 'tempArray' and assign
    //the array coming in to it
    var tempArray = inArr.get();

    //error checking section
    //check if arrays come in correctly on startup
    //if no array comes in just return to avoid errors
            showingError = false;
            //set ui to null if the input is not an array
    //set outArray to tempArray
