How to increase each number in a string?

In JavaScript how could I replace every number in a string with that number + 20?

So, this string: "min: 300px and max: 600px, min: 800px"

Would end up as "min: 320px and max: 620px, min: 820px"

Answer 1

Maybe the shortest version:

"min: 300px and max: 600px, min: 800px".replace(/\d+/g, function(c) {
    return parseInt(c, 10) + 20;
});
