     new Element('div', { 
 
      html: v 
 
     }).inject(result); 
 
      
 
    });

<div class='wrapper'>

</div>

Answer 1

Verwenden Sie einfach das zurückgegebene Objekt:

show_response = function(obj, result) { 
     new Element('div', { 
      html: obj.songtitle 
     }).inject(result); 
};

Answer 2

Sie sollten Zugang zu der Lage sein, ist in dem Objekt direkt result["songtitle"];

show_response = function(obj, result) { 
    if (result["songtitle"]) 
     console.log(result["songtitle"]); 
    else 
     console.log("no title availble");    
    }); 

Answer 3

überprüfen, ob der Schlüssel gleich "Songtitel"

new Request.JSONP({ 
url: 'http://ip:port/stats?sid=1&json=1', 
onSuccess: function(response) { 
    show_response(response, $('post')); 
} 
}).send(); 
show_response = function(obj, result) { 
$H(obj).each(function(v, k) { 
    if(k == 'songtitle)'{ 
     new Element('div', { 
      html: v 
     }).inject(result); 
    } 

}); 

};
