JavaScript extract data from variable / array

Question

I have what I assume is an array in JavaScript that looks like this when I echo it to the console log using console.log(data.position);

c.Point {left: 98, right: 34, tmode: 15}

I am trying to get the values for left and right so I can use them elsewhere in the script. What can I try?

Answer 1

The console formatting of your object simply states that the object you're logging ( data.position ) is of class c.Point , with properties left , right and tmode .

To access these properties, just do it as if it's any other JavaScript object:

var left = data.position.left;
var right = data.position.right;

// example: do something with left and right
console.log(left, right);                              // prints '98 34'

or

// example: do something with data.position.left and data.position.right directly
console.log(data.position.left, data.position.right);  // prints '98 34'

Answer 2

Es6 way using object.keys you can do this very easily

    var boo ={left: 98, right: 34, tmode: 15};
    var keys = Object.keys(boo); 

    console.log(keys);
    //["left", "right", "tmode"]0: "left"1: "right"2: "tmode"length: 3__proto__: Array[0]
    // now for getting specific keys using there index
    let leftKey = keys[0];
    let rightKey = keys[1];
    console.log(leftKey); //get left key 
    console.log(rightKey); //get right key 

Now in order to get the value of those keys do this,

console.log(boo[leftKey]); //98
console.log(boo[rightKey]) // 34

But as everyone mentioned that data.position is returning the object so, i believe you can access the value using data.position.KEYNAME
