Pajarito de twitter volando en web...

Escrito por Administrador, en localhost, twitter-js
Habrás visto que en muchas web está el pajarito de twitter volando sin parar cada vez que subes o bajas con el scroll del mouse pues bien aquí les traigo los .js y las imagenes a usar con una breve explicación de cómo usarlo ya que esta red social está en constante crecimiento y este sería un recurso más para nuestras web..

Archivos para la utilización de este Script :

index.html
twitter.js
jquery.js
twitter.png
Vas a crear el index.html y vas a colocar entre <head> y </head> los enlaces a los jQuery y la imagen que va a dar el efecto , colocandolo de esta forma.
<script src="js/twiter.js" type="text/javascript"></script>
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript"> var birdSprite='images/twiter.png';
var targetElems=new Array('img','hr','table','td','div','input','textarea','button','select','ul','ol','li','h1','h2','h3','h4','p','code','object','a','b','strong','span');
var twitterAccount = 'http://twitter.com/victorquimis';
var twitterThisText ='';tripleflapInit(); 
  </script>
Vamos a anlizar esto un poco : <script src="js/twiter.js" type="text/javascript"></script> En esta línea vas a colocar la ruta al twitter.js que vamos a crear mas adelante. <script type="text/javascript" src="js/jquery.js"></script> Aquí vamos a incorporar la ruta al jquery que tendremos que descargar desde la web del autor. var birdSprite='images/twiter.png'; aquí tendremos que colocar la ruta a la imagen que se encuentra mas adelante. var twitterAccount = 'http://twitter.com/victorquimis'; aquí tendremos que cambiar la cuenta de twitter por la tuya .
Creamos el archivo twitter.js y coloquemos el siguiente codigo sin modificar nada.
