How to use JavaScript regex over multiple lines?

Question

var ss= \"
aaaa\\nbbb\\nccc
ffffd\";
var arr= ss.match( //gm );
alert(arr);     // null

I\'d want the PR

[.\n] doesn't work, because dot in [] (by regex definition; not javascript only) means the dot-character. You can use (.|\n) (or (.|[\n\r])) instead.
