How to remove white spaces in between a string

Hi,
Can some one please tell me the regexp in javascript
to remove white spaces from between a string.
and then convert the upper case charecters to lower case.

I have a string of the format :

AAAAAA AAAAA AAAAA#AAAAA AAAAA#AAA AAAA AAAA#

Thanks,
Himi

 

Try

string.replace(/\s/g, "");
string.toLowerCase();

 

that's good job, thank
