Hi all

Can someone please explain to me exactly what this code is doing please i would be very grateful

function ValidatorTrim(s)
{
var m = s.match(/^\s*(\S+(\s+\S+)*)\s*$/);
return (m == null) ? "" : m[1];
}

I think, it's using a regular expression to check if there is anything but white space. If it's all whitespace, then it returns "", otherwise, I think it's returning the trimmed content.

You could use a loop to run a bunch of strings through it and see what it does.
