JS实现对json对象排序并删除id相同项功能示例

本文实例讲述了JS实现对json对象排序并删除id相同项功能。分享给大家供大家参考，具体如下：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>www.jb51.net json排序并删除ID相同项</title>
</head>
<body>
<script type="text/javascript">
var data=[
{
 "distance": 10,
 "name": "lv",
 "id": 1
},
{
 "distance": 1,
 "name": "lv",
 "id": 1
},
{
 "distance": 12,
 "name": "lv",
 "id": 3
},
{
 "distance": 18,
 "name": "lv",
 "id": 4
},
{
 "distance": 5,
 "name": "lv",
 "id": 5
},
{
 "distance": 12,
 "name": "lv",
 "id": 6
}
]
//根据distance排列data
function sortNumber(a,b)
{
 return a.distance - b.distance
}
data.sort(sortNumber);
//去除id相同并且距离较大的数据
for(var i=0; i < data.length; i++) {
 for(var j=i+1; j < data.length; j++) {
  if(data[i].id == data[j].id) {
   data.splice(j,1);
  }
 }
}
console.log(data);//打印最终数据
</script>
</body>
</html>

运行结果：
