Converting a String into an Array

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var sValue:String = "a,b,c,d,e,f";
        var aValues:Array = sValue.split(",");
        for (var i = 0; i < aValues.length; i++){
           trace(aValues[i]);
        }
    }
  }
}
a
b
c
d
e
f

Converting Strings to Arrays

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){

    var keywords:String = "people, new york, friends, picnic";
    var tags:Array = keywords.split(",");
    trace(tags);
    }
  }
}

If you use another delimiter in the string, you need to specify it as the argument for the

 
split() method appropriately.
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var sValue:String = "a b c d e f";
        var aValues = sValue.split(" ");
        for (var i = 0; i < aValues.length; i++){
           trace(aValues[i]);
        }
    }
  }
}
a
b
c
d
e
f

Parsing a String into Words

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){

        var example:String = "This is a string of words";
        
        var words:Array = example.split(" ");
        
        for ( var i:int = 0; i < words.length; i++ ) {
          trace( words[i] );
        }
    }
  }
}

split() method can be called using a RegExp object instead of a string as the delimiter

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var reCase:RegExp = new RegExp("[ ,]", "ig");
        var sVal = new String("ActionScript Bible, Flash Bible");
        var aVals:Array = sVal.split(reCase);
        trace(aVals);
    }
  }
}

split method returns an array

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var example:String = "a string";
        
        var characters:Array = example.split( "" );
        
        for ( var i:int = 0; i < characters.length; i++ ) {
          trace( characters[i] );
        }
        
    }
  }
}

Use regular expression in split method

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var example:String = "Here are some words. Also, here is some punctuation!";
        var words:Array = example.split( /[^a-zA-Z0-9]+/ );
        
        for (var i:int = 0; i < words.length; i++ ) {
          trace( words[i] );
        }
    }
  }
}

Use split method to get the file name and its extension name

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){

        var filename:String = "document.jpg";
        var nameParts:Array = filename.split(".");
        
        var extensionless:String = nameParts[0];
        trace ("The filename is " + extensionless);
        
        var extension:String = nameParts[1];
        trace ("The file extension is " + extension);
    }
  }
}

Use split(String, index) to split String to array of strings

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var sentence:String = "The quick brown fox jumped over the lazy dog";
        var words:Array = sentence.split("", 4); // limit to 4 elements.
        trace(words);
    }
  }
}

Use split(String) method to split String to array of strings

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var state:String = "Mississippi";
        var foo:Array = state.split("ss");
        trace(foo);
    }
  }
}

Use split to convert string to string array

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){

        var example:String = "Here are some words. Also, here is some punctuation!";
        
        var words:Array = example.split( " " );
        
        for ( var i:int = 0; i < words.length; i++ ) {
          trace( words[i] );
        }
    }
  }
}
