JSON文件只显示最后一个条目，尽管id不同

我的json文件如下:

var obj = {
 Dilse : {"name":"Dil Se Re","length":"5:40","songType":"Romantic"},
 Dilse : {"name":"Jiya Jale","length":"3:50","songType":"Self Description"},
 Dilse : {"name":"Chaiyya Chaiyya","length":"4:30","songType":"Masti"},
 Rockstar : {"name":"Sadda haq","length":"5:40","songType":"Romantic"},
 Rockstar : {"name":"Tum ho Pas Mere","length":"3:50","songType":"Self Description"},
 Rockstar : {"name":"Sheher me","length":"4:30","songType":"Masti"},
}

我想在点击Dilse时检索Dilse条目，在点击Rockstar时检索Rockstar条目。我已经在我的页面上有Dilse和Rockstar条目。

JS函数如下:

function dilSe(){
            document.getElementById("div0").innerHTML = ""; var k =0;
            if(xhr.readyState==4){
            if(xhr.status==200){
                var data=xhr.responseText;
                var arr=eval(data);
                for(var i=0;i<3;i++){             //I dont know if I should itearte like this !?
                            var link=document.createElement('a');
                            link.id='name1'+k++;
                            link.innerHTML="Song Name: " +obj.Dilse.name+"<br/>"+"Song Length: "+obj.Dilse.length+"<br/>"+"Song Type: "+obj.Dilse.songType+"<br/><br/>";
                            console.log("link.id is "+link.id);
                            link.setAttribute('href','#');
                            link.addEventListener('click',albums[link.id]);
                            div0.appendChild(link);
                            } 
                }else{
                    div0.innerHTML="Oops, error in communication!";
                    div0.style.color="red";
                }
            }
}

function rockStar(){
            document.getElementById("div0").innerHTML = ""; var k =0; var r=3;
            if(xhr.readyState==4){
            if(xhr.status==200){
                var data=xhr.responseText;
                var arr=eval(data);
                for(var i=0;i<3;i++){       //I dont know if I should itearte like this !?
                            var link=document.createElement('a');
                            link.id='name2'+k++;
                            link.innerHTML="Song Name: " +obj.Rockstar.name+"<br/>"+"Song Length: "+obj.Rockstar.length+"<br/>"+"Song Type: "+obj.Rockstar.songType+"<br/><br/>";
                            console.log("link.id is "+link.id);
                            link.setAttribute('href','#');
                            console.log("obj.rockstar.name is "+obj.Rockstar.name);
                            link.addEventListener('click',albums[link.id]);
                            div0.appendChild(link);
                            } 
                }else{
                    div0.innerHTML="Oops, error in communication!";
                    div0.style.color="red";
                }
            }
}

但最后我得到的是Dilse的最后一个条目(即Chaiyya Chaiyya)和Rockstar的最后一个条目(即Sheher me)。我希望所有三个条目应该显示。
