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) {

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

};

<div class='wrapper'>
    <div id='post'></div>
</div>

Answer 1

您应该可以直接访问对象中的 is result["songtitle"];

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

Answer 2

检查密钥是否等于"songtitle"

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);
    }

});

};

Answer 3

只需使用返回的对象：

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