Answer 1

You can do it like this:

var myString = "minmaxSize12-20";
var myRegexp = /(\d+)-(\d+)/g; // Numbers dash Numbers
var match = myRegexp.exec(myString);
alert(match[1]);  // 12
alert(match[2]);  // 20

Answer 2

Something like this should work:

var str = 'minmaxSize12-20';
var range = str.replace(/^.*?Size/i, ''); // returns 12-20

Answer 3

Simply :

"minmaxSize12-20".match(/(\d+)-(\d+)/)

or even

/(\d+)-(\d+)/.exec("minmaxSize12-20");
