Here’s a simple, two line function for removing spaces (can be adapted for any other character) from a string in AS3. I used it for removing any spaces typed into a Post Code.
public function stripspaces(originalstring:String):String
{
var original:Array=originalstring.split(” “);
return(original.join(“”));
}
All we’re doing is splitting the array using the space character and then joining that array back together into a string with no delimiter, thus eliminating the space.

Nice! Thanks for taking the time to write this and make it available!
be aware that when copying and pasting this code you will probably have to redo the ” as they go a bit funny due to the copy/paste
Thanks. This worked like a charm.
Very useful. Thank you very much!
I modified this to convert spaces to URL-encoded spaces (%20). Thanks for the help!
Much simpler:
myString.replace(/\s+/g, ”));
function strip(original, of_what )
{
return (original.split( of_what || ” “)).join(“”);
}
Probably a bit more useful …
Also the second, optional, argument can be either string or an regular expression …

I defy any C# “afficionado” to show me parallel to this, in her favourite language ;o)
if (“function” !== typeof “”.minus)
String.prototype.minus = function( what_ ) {
///
/// “ABCBDBEB”.minus(“B”), returns : “ACDE”
/// Argument is optional, by default it is one space char
/// myText.minus(), returns myText without spaces
/// argument can be an regular expression
/// reg.exp. given does not require ‘g’ or ‘m’ modifier
/// if argument is not found in the original, the original is returned
///
return (this.split(what_ || ” ” )).join( “” ) ;
}

Thanks!
Thank you so much for the tutorial!!! It worked flawlessly! I modified it so that it removed extra vertical spaces in an external text document.
Hi
I don’t know if someone else has mentioned this but you can use stuff like:
var inString:String = ” this has whitespace”;
var inString2:String = “this has no whitespace”;
var a:Array = inString.split(/^\s+/);
var b:Array = inString2.split(/^\s+/);
Any leading whitespace is removed , you can use different flags to adapt to your needs
Nice post though
All the best
