一.首先引入所申請的ak金鑰<script type="text/javascript" src="http://api.map.baidu.com/api?ak=PlhFWpA02aoURjAOpnWcRGqw7AI8EEyO&v=2.0&services=false"></script> 二.簡單樣式處理一下body, html{width: 100%;height: 100%;margin:0;font-family:"微軟雅黑";}#allmap{height:100%;width:100%;}#map span{display:block; width:20px; height:32px;background:url(http://wx.58haha.cn/1.png);position:fixed; left:50%; top:50%; margin-left:-10px; margin-top:-16px;z-index:999;}三.html程式碼佈局<div id="map"><span></span></div><div id="allmap"></div>四.js程式碼如下$(function(){var map = new BMap.Map("allmap");    var point = new BMap.Point(116.501573, 39.900877);    map.centerAndZoom(point, 16)// 定位物件var geoc = new BMap.Geocoder();var geolocation = new BMap.Geolocation();geolocation.getCurrentPosition(function(r){if(this.getStatus() == BMAP_STATUS_SUCCESS){var mk = new BMap.Marker(r.point);map.addOverlay(mk);map.panTo(r.point);//$("#start_point").val(r.point.lng+','+r.point.lat);alert("當前位置經度為:"+r.point.lng+"緯度為:"+r.point.lat);setLocation(r.point);map.addEventListener("dragend",function(){                var centerPoint=map.getCenter();                //alert(centerPoint.lng + " " +centerPoint.lat);                map.clearOverlays();//清空原來的標註                var marker = new BMap.Marker(new BMap.Point(centerPoint.lng, centerPoint.lat)); // 建立點map.addOverlay(marker);    //增加點                  marker.setPosition(400, 400)                var point = new BMap.Point(centerPoint.lng, centerPoint.lat);                var gc = new BMap.Geocoder();                gc.getLocation(point, function(rs) {                    var addComp = rs.addressComponents;                    addr = addComp.province +" "+ addComp.city +" "+ addComp.district +" "+  addComp.street +" "+ addComp.streetNumber;alert(addr);                });            });}else {$("#start").attr("placeholder","請輸入您的當前位置")alert('無法定位到您的當前位置，導航失敗，請手動輸入您的當前位置！'+this.getStatus());}},{enableHighAccuracy: true});//獲取地理位置的函式function setLocation(point){geoc.getLocation(point, function(rs){var addComp = rs.addressComponents;var result = addComp.province + addComp.city + addComp.district + addComp.street + addComp.streetNumber;//$("#start").val(result);//$("#start_location").val(result);alert("當前的位置為:"+result);});}});
