使用百度地图

1.输入地点显示

map.centerAndZoom("广州天河区车陂",16)

	function theLocation(){
		var city = document.getElementById("cityName").value;
		if(city != ""){
			map.centerAndZoom(city,11);      // 用城市名设置地图中心点
		}
	}

2.在地图标记地址

<!DOCTYPE html>

<head>
	<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
	<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
	<style type="text/css">
	body, html{width: 100%;height: 100%;margin:0;font-family:"微软雅黑";}
	#allmap {width: 100%; height:500px; overflow: hidden;}
	#result {width:100%;font-size:12px;}
	dl,dt,dd,ul,li{
		margin:0;
		padding:0;
		list-style:none;
	}
	p{font-size:12px;}
	dt{

	}
	dd{

	<title>鼠标绘制工具</title>
</head>
<body>
	<div id="allmap" style="overflow:hidden;zoom:1;position:relative;">	
		<div id="map" style="height:100%;-webkit-transition: all 0.5s ease-in-out;transition: all 0.5s ease-in-out;"></div>
	</div>

	<script type="text/javascript">
	// 百度地图API功能
    var map = new BMap.Map('map');
    var poi = new BMap.Point(116.307852,40.057031);
    map.centerAndZoom(poi, 16);
    map.enableScrollWheelZoom();  
    var overlays = [];
	var overlaycomplete = function(e){
        overlays.push(e.overlay);
    };
    //实例化鼠标绘制工具
    var drawingManager = new BMapLib.DrawingManager(map, {
        isOpen: true, //是否开启绘制模式
        //enableDrawingTool: true, //是否显示工具栏
        drawingToolOptions: {
            anchor: BMAP_ANCHOR_TOP_RIGHT, //位置
            offset: new BMap.Size(5, 5), //偏离值
        }
    });  
	 //添加鼠标绘制工具监听事件，用于获取绘制结果
    drawingManager.addEventListener('overlaycomplete', overlaycomplete);
    map.addEventListener("click",function(e){
		console.log(e.point.lng + "," + e.point.lat)
	});

</script>
</body>
</html>

3.获取用户地址，规划路线

<html>
<head>
	<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
	<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
	<style type="text/css">
		body, html{width: 100%;height: 100%;margin:0;font-family:"微软雅黑";}
		#allmap{height:500px;width:100%;}
		#r-result{width:100%; font-size:14px;}
	</style>
	<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=nVQ3ub7penqoC2Yf2qQm8wogcWk5hQI1"></script>
	<title>城市名定位</title>
</head>
<body>
	<div id="allmap"></div>
</body>
</html>
<script type="text/javascript">
	// 百度地图API功能
	var map = new BMap.Map("allmap");
	map.centerAndZoom(new BMap.Point(112.391295,22.250549),13);
	map.enableScrollWheelZoom(true);
	
	// 用经纬度设置地图中心点
	function theLocation(){
		map.clearOverlays(); 
		var new_point = new BMap.Point(112.391295,22.250549);
		var marker = new BMap.Marker(new_point);  // 创建标注
		map.addOverlay(marker);              // 将标注添加到地图中
		map.panTo(new_point);      
	}
	theLocation()

	var b
	var a = new BMap.Point(112.391295,22.250549);

	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);
		alert('您的位置：'+r.point.lng+','+r.point.lat);
		b = new BMap.Point(r.point.lng,r.point.lat);
		var driving2 = new BMap.DrivingRoute(map, {renderOptions:{map: map, autoViewport: true}});
		driving2.search(a, b);
	}
	else {
		alert('failed'+this.getStatus());
	}


	

});
