define number, is `a` a number in this case ? Do you mean digit and if so do you mean decimal digit or hex? – HopefullyHelpful Jun 16 '16 at 03:14

what I want to get is 1 and 6. I need to split it to get only 1 and 6 and I only want whole number I want to ignore the floating numbers – newbie Jun 16 '16 at 03:15

You can use `match`. `str.match(/\d+/g)`. To get the values in Number format `str.match(/\d+/g).map(Number)` – Tushar Jun 16 '16 at 04:53

Use this pattern:
RegExp: /([0-9]*[0-9])/gm
pattern: ([0-9]*[0-9])
flags: gm
1 capturing groups:
group 1: ([0-9]*[0-9])
See more at: http://regexr.com/v1?393a1
Option 2:
RegExp: /(\d+)/gm
pattern: (\d+)
flags: gm
1 capturing groups:
group 1: (\d+)

`/a*a/` is equivalent to `/a+/`, and `/[0-9]/` is equivalent to `/\d/` (in JavaScript anyway). – p.s.w.g Jun 16 '16 at 03:23

You can use String.prototype.split() with RegExp /\D|\d+\.\d+/ to split characters that are not digits, or digits followed by . character followed by digits to handle for example 2.456, Array.prototype.filter() with parameter Boolean to remove empty strings from result
console.log("id=1,6,a,2.456".split(/\D|\d+\.\d+/).filter(Boolean))
