页面的head部分，需调用百度地图的API接口，并引入一个JS文件，代码如下：

<script src="http://api.map.baidu.com/getscript?v=2.0&ak=A1LU7iHS0avqQwPLAxbhKn0UYSQCuRVH&services=&t=20170803155555"></script>
<script type="text/javascript" src="js/lushu_min.js"></script>

页面的body部分，仅需一个指定id的div容器用来装载地图，代码如下：

<div id="map"></div>

页面的底部，创建地图实例并设置好各类参数，代码如下：

<script type="text/javascript">
var map = new BMap.Map("map");//创建地图实例
//创建起点
var pt_start = new BMap.Point(117.270591,23.812975);
var startIcon = new BMap.Icon("images/start.png", new BMap.Size(36,36));
var markerStrat = new BMap.Marker(pt_start,{icon:startIcon});  // 创建标注
map.addOverlay(markerStrat);             // 将标注添加到地图中
//创建终点
var pt_end =  new BMap.Point(116.885031,23.689196)//new BMap.Point(115.559445,22.859811);
var endIcon = new BMap.Icon("images/end.png", new BMap.Size(36,36));
var markerEnd = new BMap.Marker(pt_end,{icon:endIcon});  // 创建标注
map.addOverlay(markerEnd);             // 将标注添加到地图中

map.centerAndZoom(pt_start,15);
map.enableScrollWheelZoom();

//创建司机
var pt;
var marker2;
var index=0;

	 });
	marker2.setLabel(label);
	map.centerAndZoom(pt,13);
	if(distance==0){
		var polyline = new BMap.Polyline(points);//创建折线
		map.addOverlay(polyline);//覆盖折线到地图上
		clearInterval(oTime);
		map.centerAndZoom(pt_end,13);
	}
},1000);

	  });
	marker2 = new BMap.Marker(pt,{icon:myIcon});  // 创建标注
	map.addOverlay(marker2);  // 将标注添加到地图中*/
