百度地图API精准定位并显示门牌地址 - HTML代码示例

<div id='initMap' style='display: none;'></div>
<script type='text/javascript' src='//api.map.baidu.com/api?v=3.0&ak=gHILVzmuMIlwy2Z5lE33dedbeI87UIZK'></script>

var zd = getLocation();
	function getLocation() {
		// 百度地图API功能
		var map = new BMapGL.Map('initMap');
		var point = new BMapGL.Point(116.331398, 39.897445);
		map.centerAndZoom(point, 12);
		var geolocation = new BMapGL.Geolocation();
			geolocation.getCurrentPosition(function (r) {
				console.log(r)
				if (this.getStatus() == BMAP_STATUS_SUCCESS) {
					console.log('您的位置：' + r.point.lng + ',' + r.point.lat);
					x_pi = 3.14159265358979324 * 3000.0 / 180.0;
					x = r.point.lng;
					y = r.point.lat;
					z = Math.sqrt(x * x + y * y) + 0.00002 * Math.sin(y * x_pi);
					theta = Math.atan2(y, x) + 0.000003 * Math.cos(x * x_pi);
					lngs = z * Math.cos(theta) + 0.0065;
					lats = z * Math.sin(theta) + 0.006;
					var point = new BMapGL.Point(lngs, lats);//用所定位的经纬度查找所在地省市街道等信息
					
					var gc = new BMapGL.Geocoder();
					
					gc.getLocation(point, function (rs) {
						var addComp = rs.addressComponents;
						console.log(rs.address);//地址信息
						alert(rs.address);

<p>这段代码实现了调用百度地图API进行精准定位，并在弹窗中显示门牌地址。</p>
