Parse Javascript Array

Question

I have an array: {r=1, g=4, b=6} How do i go about getting the value of each (r,g,b) into a separate variable?

Answer 1

JavaScript does not have associative arrays. So this is legal:

var my_rgb_arr = [1, 4, 6]

Or this can be legal:

var my_rgb_obj = { r: 1, g: 4, b: 6 };

To access the array:

my_rgb_arr[0]; // r
my_rgb_arr[1]; // g
my_rgb_arr[2]; // b

And the object:

my_rgb_obj.r; // r
my_rgb_obj.g; // g
my_rgb_obj.b; // b

Which are you dealing with?

Answer 2

• That's not an array
• That's almost an object constant, but you need ":" instead of "="
• The values already are in separate variables, or would be if the syntax was OK

That's the syntax for instantiating an "object constant" and populating it with properties and values. If you assign that value (the whole thing) to another variable, then you'll be able to get at the properties.

var rgb = { r: 1, g: 4, b: 6};
var rByItself = rgb.r;
