I have a small 70x70 box in an HTML player I built where I wish to place in the album artwork to coincide with my now playing information from my shoutcast server. Is there a way, using the artist-song information the shoutcast server provides, that I can search a web service (amazon/last.fm) and have it place the (most likely) album cover there?
Here is the JS code I'm using now:
jQuery(document).ready(function() {
pollstation();
//refresh the data every 30 seconds
setInterval(pollstation, 30000);
});
// Accepts a url and a callback function to run.
function requestCrossDomain( callback ) {
// Take the provided url, and add it to a YQL query. Make sure you encode it!
var yql = 'http://s7.viastreaming.net/scr/yql.php?port='+port+'&username='+user+'&callback=?';
// Request that YSQL string, and run a callback function.
// Pass a defined function to prevent cache-busting.
jQuery.getJSON( yql, cbFunc );
function cbFunc(data) {
// If we have something to work with...
if ( data ) {
// Strip out all script tags, for security reasons. there shouldn't be any, however
data = data[0].results.replace(/<script[^>]*>[\s\S]*?<\/script>/gi, '');
data = data.replace(/<html[^>]*>/gi, '');
data = data.replace(/<\/html>/gi, '');
data = data.replace(/<body[^>]*>/gi, '');
data = data.replace(/<\/body>/gi, '');
// If the user passed a callback, and it
// is a function, call it, and send through the data var.
if ( typeof callback === 'function') {
callback(data);
}
}
// Else, Maybe we requested a site that doesn't exist, and nothing returned.
else throw new Error('Nothing returned from getJSON.');
}
}
function pollstation() {
requestCrossDomain(function(stationdata) {
var lines = stationdata.split('|+|');
jQuery('#sname').html(lines[0]);
jQuery('#sgenre').html(lines[1]);
jQuery('#clisteners').html(lines[2]);
jQuery('#bitrate').html(lines[3]);
jQuery('#artist_block').html('' + jQuery.trim(lines[4]) + '');
var prev = lines[5].split('+|+');
jQuery('#np_table').html('');
for (var i = 0; i < 8; i++)
{
if(typeof(prev[i]) != 'undefined')
{
jQuery('#np_table').append('<tr>'+'<td>'+ prev[i] + '</td>'+'</tr>');
jQuery("tr:odd").css("background-color", "#154270");
}
}
jQuery('#mplayers').html(lines[6]);
jQuery('#mobile').html(lines[7]);
jQuery();
} );
}
and here's the HTML:
<div id="col_left">
<div id="now_playing">
<div id="np_ribbon"><span>Now Playing</span></div>
<div id="np_img"><img name="nowplayingimage" src="" width="70" height="70" alt="album cover" style="background-color: #000000" /></div>
<div id="artist_block">
<span class="artist_name"><strong>Artist:</strong> Artist name</span><br />
<span class="song_name"><strong>Song:</strong> "song title"</span><br />
<span class="album_name"><strong>Album:</strong> Album Name</span> <br />
</div>
<div id="player">
<div id="container"><script type="text/javascript" src="http://shoutcast.mixstream.net/js/external/flash/s7.viastreaming.net:8790:0:::999999:::1"></script></div>
</div>
</div><!-- end now playing -->
<div id="recent">
<div class="table_title">Recently Played</div>
<table id="np_table">
</table>
</div><!-- end recent -->
</div><!-- end col_left -->
So naturally, I want the image to appear where the div "np_img" is. Any ideas what code to use and how to implement it. You can probably tell by my code that I'm an amateur so please be clear and gentle. :)
You can use the iTunes search API. It supports JSONP so you can use it directly within your webpage, without worrying about cross-domain.
As @Brad mentioned, iTunes has terms of use. In particular:
(...) provided such Promo Content: (i) is placed only on pages that promote the content on which the Promo Content is based; (ii) is proximate to a "Download on iTunes" or "Available on the App Store" badge (as approved by Apple) that acts as a link directly to pages within iTunes or the App Store where consumers can purchase the promoted content. (...)
Here's how the code looks like:
function refreshArtwork(artist, track) {
$.ajax({
url: 'http://itunes.apple.com/search',
data: {
term: artist + ' ' + track,
media: 'music'
},
dataType: 'jsonp',
success: function(json) {
if(json.results.length === 0) {
$('img[name="nowplayingimage"]').attr('src', '');
return;
}
// trust the first result blindly...
var artworkURL = json.results[0].artworkUrl100;
$('img[name="nowplayingimage"]').attr('src', artworkURL);
}
});
}
