Replace space with "+". \s = invalid char.

Hi, I'm trying to replace all the instances of " " with a "+" using regular expression.

checking out on various site the expresion for a space is "\s". So I type in confidently.

-----------------------------------------------------
<script language="javascript">
str = "hello me";

reg = (\s)
str.replace(reg,' ')

alert(str);
</script>
-----------------------------------------------------

and get "invalid character "\". Anyone know about these regular expressions out there?

Cheers

Sandy

Regular expressions are not delimited with parentheses. Try
reg = /\s+/;
str.replace(reg,'+')
the + in the regex indicates 1 or more occurences of a white-space character:
including /r /n /t and /f
