    Unhappy Regex.Replace syntax error from RegexBuddy code

    Error: syntax error
    Line: 26, Column: 30
    Source Code:
    text = Regex.Replace(text, @"\s+", "");
    ----------------------------^

    also tried:
    Code:
    text = Regex.Replace(text, @'\s+', '');
    Here's full source:
    Code:
    function getCharDimArr(text, font, fontSizeStr, measureBox) {
    	//remove all spaces from text
    	try {
    		text = Regex.Replace(text, @'\s+', '');
    	} catch (ArgumentException ex) {
    		alert('Syntax error in the regular expression in removing spaces in getCharWH() func');
    	}

    I got the code verbatim from RegexBuddy, how can I fix syntax error?
    \s+ is regex shorthand for all space characters.

    -thanks

    The syntax you've shown is not JavaScript. It looks to be some bastardised Java.

    In JavaScript:
    - The delimiters around regex literals are not @" and " or @' and ', both opening and closing delimiter are /. Flags are placed after the closing delimiter.
    - The Replace function is named replace.
    - The replace function is a method on strings, not on the RegExp object.
    - The replace function takes a first argument being a regex and a second argument being either a static string with PERL-inspired replacement monikers, or a function object.
    - Exceptions catches are not typed.
