Open a URL in new Browser window in Flex/ActionScript

ActionScript uses the function navigateToURL(var1:URLRequest,targetWindow:String ) to Open a URL link in a browser.


For the simplictiy, there goes a function. Just calling the function with the desired URL as String will open the URL in a new window.

public function jumpTo(jumpLoc:String):void
 navigateToURL(new URLRequest(jumpLoc),"_blank");


Call the function defined above with the URL as a String-type parameter.

String Replace Function in Flex ActionScript

There is a function String.replace() which returns the result string. But note, this only replaces the first occurance of given string/expression!


So, to actually replace all the occurances of given string/expression, you must loop through until all the matches are replaced. Code & Documentation

However, there is another easy customized function to automatically replace all the occurance of given match. Here goes the customized function:

public function str_replace(mainStr:String, str1:String, str2:String):String
 var temp:Array = mainStr.split(str1);
 var tempStr:String = temp.join(str2);
 return tempStr;


var myStr:String = str_replace("a_b_c", "_" , "1");   // a1b1c1

Splitting Strings in Flex ActionScript: split method

Using Split method on a given String, you can get an array of Substrings. Each substring is formed from the given String by spliting them according to another given string, or expression. That means, the another string separates or splits the mother-String and split it into array of Substrings.


var myStr:String = "first_second_third";
var subStr:Array = myStr.split("_");

Now subStr[0] will contain “first”, subStr[2] will contain “third”;

More Practical Example:

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);
