在json中删除额外的<br>标签

Question

我正在制作一个带有JSON的音乐列表进行搜索，并在用户输入一些文本后立即显示。那就是：

var music = [ 
{"name": "Abba"}, 
{"name": "Justin Bieber"}, 
{"name": "Taylor Swift"}, 
{"name": "David Guetta"}, 
{"name": "Usher"}, 
{"name": "LMFAO"}, 
{"name": "Enrique Iglesias"}, 
{"name": "Pitbull"}, 
{"name": "Eminem"}, 
{"name": "Nickelback"}, 
{"name": "Rihanna"}, 
{"name": "Queen"}, 
{"name": "Linkin Park"}, 
{"name": "Lady Gaga"}, 
{"name": "Gym Class Heroes"}, 
{"name": "Maroon 5"}, 
{"name": "heyhihello"}, 
{"name": "Paramore"}, 
{"name": "Owl City"}, 
{"name": "Black Eyed Peas"}, 
{"name": "Coldplay"}, 
{"name": "White Stripes"}, 
{"name": "Selena Gomez"}, 
{"name": "Selena Gomez and The Scene"}, 
{"name": "Creed"}, 
{"name": "Hinder"} 

]; 
$(document).ready(function(){ 
sendm = function(txt){ 
var st = txt.toLowerCase(); 
if(st.length>0){ 
var res = new Array(); 
$.each(music, function(i, item) { 
    if(item.name.substring(0, st.length).toLowerCase()===st){ 
     res[i] = item.name; 
    } 
}); 
document.getElementById("main-p").innerHTML = res.join("<br>"); 
} 
}; 
}); 

现在，如果用户输入“亚瑟小子”，在结果中，它会留下，因为
标签的几行。我如何删除它们？

Answer 1

变化：

res[i] = item.name; 

要：

res.push(item.name); 

那么你的数组的长度会被发现的，而不是找到了最后一场比赛的指数匹配的数目。取而代之的

$.each(music, function(i, item) { 
    if(item.name.substring(0, st.length).toLowerCase()===st){ 
     res[i] = item.name; 
    } 
}); 

Answer 2

做

$.each(music, function(i, item) { 
    if(item.name.substring(0, st.length).toLowerCase()===st){ 
     res.push(item.name); 
    } 
});
