actionscript find and convert text to url
- by gravesit
I have this script that grabs a twitter feed and displays in a little widget. What I want to do is look at the text for a url and convert that url to a link.
public class Main extends MovieClip
{
private var twitterXML:XML; // This holds the xml data
public function Main()
{
// This is Untold Entertainment's Twitter id. Did you grab yours?
var myTwitterID= "username";
// Fire the loadTwitterXML method, passing it the url to your Twitter info:
loadTwitterXML("http://twitter.com/statuses/user_timeline/" + myTwitterID + ".xml");
}
private function loadTwitterXML(URL:String):void
{
var urlLoader:URLLoader = new URLLoader();
// When all the junk has been pulled in from the url, we'll fire finishedLoadingXML:
urlLoader.addEventListener(Event.COMPLETE, finishLoadingXML);
urlLoader.load(new URLRequest(URL));
}
private function finishLoadingXML(e:Event = null):void
{
// All the junk has been pulled in from the xml! Hooray!
// Remove the eventListener as a bit of housecleaning:
e.target.removeEventListener(Event.COMPLETE, finishLoadingXML);
// Populate the xml object with the xml data:
twitterXML = new XML(e.target.data);
showTwitterStatus();
}
private function addTextToField(text:String,field:TextField):void{
/*Regular expressions for replacement, g: replace all, i: no lower/upper case difference
Finds all strings starting with "http://", followed by any number of characters
niether space nor new line.*/
var reg:RegExp=/(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
//Replaces Note: "$&" stands for the replaced string.
text.replace(reg,"<a href=\"$&\">$&</a>");
field.htmlText=text;
}
private function showTwitterStatus():void
{
// Uncomment this line if you want to see all the fun stuff Twitter sends you:
//trace(twitterXML);
// Prep the text field to hold our latest Twitter update:
twitter_txt.wordWrap = true;
twitter_txt.autoSize = TextFieldAutoSize.LEFT;
// Populate the text field with the first element in the status.text nodes:
addTextToField(twitterXML.status.text[0], twitter_txt);
}
