Bookmarklets

Bookmarklets are little javascript one-liners that aim to compose a more or less complex url often using the html DOM structure.

Samples

Beware:

1. These javascripts bookmarklets are intended to be condensed into one-liners.
2. Failing to do so, will most probably result in a mal-functioning of the bookmarklet.
3. The "..." notation is used to annotate code wrapping. Please remeber to remove it along with the linefeed when writing the script.

Wikipedia search

This script will pop-up a textbox prompting the user for a keyword and, upon submission, will return the corresponding wikipedia article (or the results listing).

javascript:( 
    function(){ 
        q=document.getSelection();
        if(!q) q=prompt('Wikipedia:');
        if(q) location.href='http://en.wikipedia.org/w/wiki.phtml?search=' + escape(q); 
    }
)()

Google Local Domain Search

This script will pop-up a textbox prompting the user to enter a keyword and, upon submission, will google a sitesearch within the current domain.

javascript:
    void(
        str = prompt("Search for:#,#")
    );
    if(str){
       location.href='http://www.google.com/search? ...
       source=ig ...
       &hl=en ...
       &as_sitesearch='+encodeURIComponent(location.href)+' ...
       &q='+escape(str).split(" ").join("+")+' ...
       &btnG=Google+Search';
    }

Google MP3 music search

This script will pop-up a textbox prompting the user to enter a keyword and, upon submission, will google applying filters that will probably return only indexes of mp3 files.

javascript:
    void(
        str=prompt("Search for:#,#")
    );
    if(str){
        location.href='http://www.google.com/search?hl=en ...
        &q=-inurl:(html|htm|php|asp|pl|cgi)+"index+of/" ...
            +mp3+'+escape(str).split(" ").join("+")+'&btnG=Search';
    }

Del.icio.us MP3 player button

This script will look throughout the DOM structure of the current document and add an audio player button in front of every mp3 filetype link.

javascript:(
    function(){
        var o = document.createElement("script");
        o.type = "text/javascript";
        o.src = "http://images.del.icio.us/static/js/playtagger.js";
        o.onload = function(){
            Delicious.Mp3.go();
        };
        document.body.appendChild(o);
    }
)()

Del.icio.us Tagger

This script will pop-up a textbox prompting the user to enter tags and, upon submission, will post the current url and respective tags to del.icio.us.

javascript:
    void(
        str=prompt("Tag this page:#,#")
    );
    if(str){
        location.href='http://del.icio.us/USERNAME? ...
        url='+encodeURIComponent(location.href)+' ...
        &title='+encodeURIComponent(document.title)+ ...
        '&v=3' ...
        &tags='+escape(str).split(" ");
    }

NOTE: would be cool if only somebody found out a way to automatically save the results to del.icio.us.

Del.icio.us search

This script will pop-up a textbox prompting the user to enter tags and, upon submission, will the user's del.icio.us bookmarks.

javascript:
    void(
        str=prompt("Search for in del.icio.us:#,#")
    );
    if(str){
        location.href='http://del.icio.us/search/? ...
            fr=del_icio_us ...
            &p='+escape(str).split(" ")+' ...
            &type=user';
    }

MailTo

This script will pop-up a textbox prompting for a message body that will be sent via email to a pre-scripted email address with a predefined subject.

javascript:
    void(
        str=prompt("Write message:#,#")
    );
    if(str){
        location.href='mailto:dumbdumb@twitty.com? ...
            subject=twitter ...
            &body=well this is my message!';
    }

Here's the html version:

<a href="mailto:dumbdumb@twitty.com?subject=twitter&body=well this is my message!">MailTwit</a>

Seeqpod

javascript:
   void(
       str = prompt("Seeqpod playlist id:#,#")
   );
   if(str){
      location.href='http://www.w3.org/2000/06/webdata/xslt...
?xslfile=http://pointpt.user.openhosting.com/~guillaume/xspf2html.xsl...
&xmlfile=http://www.seeqpod.com/api/music/getPlaylist?playlist_id='+escape(str).split(" ").join("+")+'....
&transform=Submit';
   }

   void(
       str = prompt("Playlist url:#,#")
   );
   if(str){
