一、百度地图初始化及添加基本控件
1.引入地图包
地图包网址的ak属性是你在百度地图开放平台上申请的密钥
<script type="text/javascript" src="http://api./api?v=2.0&ak=/*你的密钥*/"></script>
2.初始化地图
var map = new BMap.Map("allmap"); // 创建Map实例map.centerAndZoom("天津",14); // 初始化地图,设置城市和地图级别。
3.添加控件
//地图事件设置函数：function setMapEvent(){map.enableDragging();//启用地图拖拽事件，默认启用(可不写)map.enableScrollWheelZoom();//启用地图滚轮放大缩小map.enableDoubleClickZoom();//启用鼠标双击放大，默认启用(可不写)map.enableKeyboard();//启用键盘上下左右键移动地图}//地图控件添加函数：function addMapControl(){//向地图中添加缩放控件var ctrl_nav = new BMap.NavigationControl({anchor:BMAP_ANCHOR_TOP_LEFT,type:BMAP_NAVIGATION_CONTROL_LARGE});map.addControl(ctrl_nav);//向地图中添加缩略图控件var ctrl_ove = new BMap.OverviewMapControl({anchor:BMAP_ANCHOR_BOTTOM_RIGHT,isOpen:1});map.addControl(ctrl_ove);//向地图中添加比例尺控件var ctrl_sca = new BMap.ScaleControl({anchor:BMAP_ANCHOR_BOTTOM_LEFT});map.addControl(ctrl_sca);}
二、单击地点后经纬度转换为地址
//监听单击事件map.addEventListener("click",function(e){map.clearOverlays(); // alert(e.point.lng + "," + e.point.lat);point = new BMap.Point(e.point.lng, e.point.lat);var geoc = new BMap.Geocoder(); geoc.getLocation(point,function(rs){ var addComp = rs.addressComponents; // alert(addComp.province + ", " + addComp.city + "," + addComp.district + ", " + addComp.street + ", " + addComp.streetNumber); console.log(addComp);});var marker = new BMap.Marker(point);map.addOverlay(marker);document.getElementById("allmap").value = e.point.lng+ "," + e.point.lat;});
三、完整代码如下
