JavaScript mins and seconds into seconds

Question

I have a string being grabbed from a page in the format "4m 26s", how can I strip this into just seconds?

Many thanks,

Simple regex will work:

var s = '21m 06s';

var m = /(\d{1,2})m\s(\d{1,2})s/.exec(s);

var mins = parseInt(m[1], 10);
var secs = parseInt(m[2], 10);
