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 name="viewport" 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="http://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="http://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 id="container"></div>
</body>
</html>
