Code snippet: Trimming texts in AS2

From time to time some of us still have to code in oldskool ActionScript 2. A few days ago a colleague asked me for a function for trimming ‘new line’ (\n), ‘carriage return’ (\r) characters, spaces, …
So I ended up searching my archives for a code snippet to archive this functionality and look what I found:

This code takes out the characters that are defined in the character_array variable:

// remove \r , \n , & from string
function trimTextChars(text_str):String
{
    var character_array:Array = new Array(chr(13), chr(10), chr(38));
    var inputstring:String = text_str;
    for(i=0 ; i < character_array.length ; i++)
    {
        var temp_array = inputstring.split(character_array[i]);
        for(j=0 ; j < temp_array.length ; j++) temp_array[j] = trim(temp_array[j]);
        inputstring = temp_array.join(" ");
    }
 
    return inputstring;
}

This code removes leading and trailing spaces from a given string:

// Trim leading and trailing spaces from string
function trim(txt_str):String
{
    while (txt_str.charAt(0) == " ") txt_str = txt_str.substring(1, txt_str.length);
    while (txt_str.charAt(txt_str.length-1) == " ") txt_str = txt_str.substring(0, txt_str.length-1);
 
    return txt_str;
}

Enjoy!
