基于高德地图API实现车辆轨迹回放并显示实时坐标

一、先上代码：

html代码：
 

 
 
 
 

js代码：
 var postData = {};
 postData['rsearch'] = rsearch;
 postData['uid'] = uid;
 postData['stime'] = stime;
 postData['etime'] = etime;
 postData['ajax'] = 1;
 var url = 'index.php?mod={$mod}&act={$act}&opt={$opt}'; //接口地址

 $.post(url,postData,function(res){
