Easy Regex (when you know how... and I don't)

[The Plankmeister]

Hi...

I hacked about for a bit and got this to work:

/^\s+/

So that it matches any whitespace characters at the start of the string. But
how can I modify it so that it matches strings made ONLY of whitespace?

Whitespace from the beginning ^ to the end $:
/^\s+$/
That wouldn't allow empty strings so maybe you want
/^\s*$/

/^\s*$/

This matches strings that only have zero or more whitespace between
start and end of the string. If you don't want to include empty strings,
change the "*" to a "+".
