Regular expression to check white space

[RuthC]

Hi, I use this regular expression to check alphanumeric with('_' and '-')

var regex_alphanumeric = /^[a-zA-Z0-9\-\_\s]{2,}$/;

but It allows white space also.Now I want to check white space also.

Please help me..


Thanks in Advance..

So do you want or you dont want to check whitespaces?
If you dont, just remove /s from your regular expressions, because /s represents all whitesspaces (space, tab, newline etc...)

var regex_alphanumeric = /^[a-zA-Z0-9\-\_]{2,}$/;

Or make your request more clear pls.
