mooUrl Ubiquity Command

Brincando com a API do Ubiquity, acabei fazendo este comando para utilizar o moourl de forma similar ao tinyurl.

Vamos então ao código:

/*
 * mooUrl command for Firefox Ubiquity extension.
 * date: 03/04/2009
 * author: Renato Aquino <renato.aquino@gmail.com>
 * add with <link rel="commands" href="mooUrl.js"/> to your page
 */
CmdUtils.CreateCommand({
 name: "moourl",
  takes: {"url to shorten": noun_type_url},
 icon: "http://moourl.com/favicon.ico",
 description: "Replaces the selected URL with a <a href=\"http://moourl.com\">MooUrl</a>",
 author: {name: "Renato Aquino", email: "renato.aquino@gmail.com"},
 license: "GPL",
 baseUrl: "http://moourl.com/create/?source=",
 preview: function( pblock, urlToShorten ){
  pblock.innerHTML = "Replaces the selected URL with ",
  jQuery.get( this.baseUrl + urlToShorten.text, function( moo ) {
   if(moo != "Error")
    pblock.innerHTML += jQuery("#milked_url",moo).text();
  });
 },
 execute: function( urlToShorten ) {
  //escaping urlToShorten will not create the right moourl
  jQuery.get( this.baseUrl + urlToShorten.text, function( moo ) {
   if(moo != "Error")
    CmdUtils.setSelection( jQuery("#milked_url",moo).text() );
  });
 }
});
