废话不多说，直接给大家贴代码了，具体代码如下所示，
关键代码如下：
<!DOCTYPE html> <html lang="zh-cn"> <head> <meta content="initial-scale=1.0, user-scalable=no" /> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <style type="text/css"> html { height:100%; } body { height:100%; margin:0px; padding:0px; } #container { height:50%; } </style> <script src="https://code.jquery.com/jquery-1.11.0.min.js"></script> <script src="http://api.map.baidu.com/api?v=1.4" type="text/javascript"></script> <script type="text/javascript" src="https://developer.baidu.com/map/jsdemo/demo/convertor.js"></script> <script> $(function () { navigator.geolocation.getCurrentPosition(translatePoint); //定位 }); function translatePoint(position) { var currentLat = position.coords.latitude;//经度 var currentLon = position.coords.longitude;//纬度 var gpsPoint = new BMap.Point(currentLon, currentLat); BMap.Convertor.translate(gpsPoint, 0, initMap); //转换坐标 } function initMap(point) { //初始化地图 map = new BMap.Map("container");//实例化容器 map.addControl(new BMap.NavigationControl());//平移缩放控件 map.addControl(new BMap.ScaleControl());//比例尺控件 map.addControl(new BMap.OverviewMapControl());//缩略地图控件 map.centerAndZoom(point, 15);//地图初始化，参数地图坐标和级别 map.addOverlay(new BMap.Marker(point));//当前位置加标记 var myZoomCtrl = new ZoomControl(); map.addControl(myZoomCtrl); function ZoomControl() { this.defaultAnchor = BMAP_ANCHOR_TOP_LEFT; //调整控件的位置 this.defaultOffset = new BMap.Size(10, 10);//通过像素调整位置 } //自定义控件，点击两下实现放大 ZoomControl.prototype = new BMap.Control(); ZoomControl.prototype.initialize = function (map) { var div = document.createElement("div"); div.appendChild(document.createTextNode("放大2级")); div.style.cursor = "pointer"; div.style.border = "1px solid gray"; div.style.backgroundColor = "white"; div.onclick = function (e) { map.zoomTo(map.getZoom() + 2); } map.getContainer().appendChild(div); return div; } } </script> </head> <body> <div></div> </body> </html>
