百度导航插件怎么用法

1、首先，导入js。举例:<!--引用百度地图API --><script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=WADcKXvvdvdvdltjf7QbMikfcFEAc3Y1OOIE"></script>备注:秘钥(src中的ak的值)自己获取

2、程序开发: 应用举例://创建和初始化地图函数： function initMap(){ createMap();//创建地图 setMapEvent();//设置地图事件 addMapControl();//向地图添加控件 addMapOverlay();//向地图添加覆盖物

3、 } function createMap(){ map = new BMap.Map("map"); map.centerAndZoom(new BMap.Point(116.278118,39.874275),16); } function setMapEvent(){ map.enableScrollWheelZoom(); map.enableKeyboard(); map.enableDragging(); map.enableDoubleClickZoom() } function addClickHandler(target,window){ target.addEventListener("click",function(){ target.openInfoWindow(window); });

4、} function addMapOverlay(){ var markers = [ {content:"",title:"",imageOffset: {width:-46,height:-21},position:{lat:39.872382,lng:116.277184}} ]; for(var index = 0; index < markers.length; index++ ){ var point = new BMap.Point(markers[index].position.lng,markers[index].position.lat); var marker = new BMap.Marker(point,{icon:new BMap.Icon("http://api.map.baidu.com/lbsapi/createmap/images/icon.png",new BMap.Size(20,25),{ imageOffset: new BMap.Size(markers[index].imageOffset.width,markers[index].imageOffset.height) })}); var label = new BMap.Label(markers[index].title,{offset: new BMap.Size(7,8)});

5、 var opts = { width: 200, title: markers[index].title, enableMessage多唉捋胝: false }; var infoWindow = new BMap.InfoWindow(markers[index].content,opts); marker.setLabel(label); addClickHandler(marker,infoWindow); map.addOverlay(marker); }; } //向地图添加控件 function addMapControl(){ var navControl = new BMap.NavigationControl({anchor:BMAP_ANCHOR_TOP_LEFT,type:BMAP_NAVIGATION_CONTROL_LARGE}); map.addControl(navControl); } var map; initMap(); </script>
