Convert String To Integer in Javascript

[Yanskopolis]

Hi, I'm trying to find a more succinct way to transform a string variable into an integer. This is my code I have at the moment:

var str = "rgb(51, 45, 32)"
 
var first = str.slice(4,6);
var second = str.slice(8,10);
var third = str.slice(12,14);
 
var integOne = parseInt(first); 
var integTwo = parseInt(second);  
var integThree = parseInt(third);
 
ctx.fillStyle = "rgba(integOne, integTwo, integThree, 0.5)";

...which works fine, but I'm pretty sure there must be a more efficient way to go about it.

I tried the following, but without success:

var str = "rgb(51, 45, 32)";
var strSliced = str.slice(4,14);
eval("ctx.fillStyle = 'rgba("+strSliced+", 0.5)'");

Is there a better way to do this?

Cheers.

Hmm, seems I got a bit mixed up as I didn't need to convert it to an integer anyway.

Mods can close/delete this thread if you want. :)

Yes, if you needed to manipulate the numbers in some way, then maybe, but since you're copying, it wasn't necessary.

I'll keep this thread. It might prove useful to someone.
