Regex using javascript to return multiple numbers into an array

Question

in another article on Stackoverflow, I found this line of code

myString = 'hello112';
myNumber = myString.match(/\d+/)[0];

In this case, the 'myNumber' variable has the value of 122.

But when I use .match for the following case, it fails:

myColor = 'rgb(210,255,105);
myNumbers = myColor.match(/\d+/);

The 'myNumbers'variable is an array, but it's length is 1 and it contains only '210' and not the other 2 numbers.

Is there a way in Javascript that I can achive something like this?

input = 'rgb(210,255,105);
output = [210,255,105];

Thank you very much.

Unless told otherwise, match() matches only the first instance, not all. You need the global "g" flag after the pattern.

match(/pattern/g);

Side note: you can't use the global modifier in conjunction with sub-group matching, but that shouldn't affect your situation.

You have to use g - global flag.

myColor = 'rgb(210,255,105)';
console.log(myColor.match(/\d+/g));
