<script type="text/javascript">
var data=[
{
 "distance": 10,

 "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
