Question

I have the following code,

public static function clearDelimeters(formattedString:String):String
{
    return formattedString.split("\n").join("").split("\t").join("");
}

The spaces i.e. “\t” are removed but the newline “\n” are not removed from the formattedString.

I even tried

public static function clearDelimeters(formattedString:String):String
{
    var formattedStringChar:String = "";
    var originalString:String = "";
    var j:int = 0;
    while((formattedStringChar = formattedString.charAt(j)) != "")
    {
        if(formattedStringChar == "\t" || formattedStringChar == "\n")
        {
            j++;
        }
        else
        {
            originalString = originalString + formattedString;
        }
        j++;
    }
    return originalString;
}

This also didn’t work.
Expected help is the reason why newline delimeters are not removed and some way to remove the newline.
Thank you in anticipation

There are a few cases that the line-end marking may be: CRLF, CR, LF, LFCR. Possibly your string contains CRLF for line endings instead of only LF (\n). And so, with all the LFs removed, some text editors will still treat CRs as line-end characters.

Try this instead:

//this function requires AS3
public static function clearDelimeters(formattedString:String):String {     
  return formattedString.replace(/[\u000d\u000a\u0008\u0020]+/g,""); 
}

Note that \t is for tab, it’s not space. Or if you’re working with HTML, <br> and <br/> are used to make line breaks in HTML but they are not line-end characters.
