Javascript Regular Expression Remove Spaces

Question

So i m writing a tiny little plugin for JQuery to remove spaces from a string  see here   function            stripSpaces   function str            var reg   new RegExp         g            return str replace reg               jQuery     my regular expression is currently      to collect all spaces   This works   however It doesn t leave a good taste in my mouth    I also tried   s   and   W   but neither worked     There has to be a better  more concise  way of searching for only spaces

I would recommend you use the literal notation  and the  s character class        return str replace   s g              There s a difference between using the character class  s and just       this will match a lot more white-space characters  for example   t r n  etc    looking for     will replace only the ASCII 32 blank space   The RegExp constructor is useful when you want to build a dynamic pattern  in this case you don t need it   Moreover  as you said     s    didn t work with the RegExp constructor  that s because you are passing a string  and you should  double escape  the back-slashes  otherwise they will be interpreted as character escapes inside the string  e g     s       s   unknown escape

str replace   s g       Works for me   jQuery trim has the following hack for IE  although I m not sure what versions it affects      Check if a string has a non-whitespace character in it rnotwhite     S      IE doesn t match non-breaking spaces with  s if   rnotwhite test    xA0            trimLeft       s xA0         trimRight      s xA0
