实例
例子 1:
本示例中,设置地址解析服务属性
var geocoder, map, marker = null; var init = function() { var center = new qq.maps.LatLng(39.916527, 116.397128); map = new qq.maps.Map(document.getElementById('container'), { center: center, zoom: 15, }); //地址和经纬度之间进行转换服务 geocoder = new qq.maps.Geocoder(); //设置服务请求成功的回调函数 geocoder.setComplete(function(result) { map.setCenter(result.detail.location); var marker = new qq.maps.Marker({ map: map, position: result.detail.location }); //点击Marker会弹出反查结果 qq.maps.event.addListener(marker, 'click', function() { alert("坐标地址为: " + result.detail.location); }); }); //若服务请求失败,则运行以下函数 geocoder.setError(function() { alert("出错了,请输入正确的地址!!!"); }); } function codeAddress() { var address = document.getElementById("address").value; //对指定地址进行解析 geocoder.getLocation(address); }

例子 2:
本示例中,设置反地址解析服务属性
var geocoder, map, marker = null; var init = function() { var center = new qq.maps.LatLng(39.916527, 116.397128); map = new qq.maps.Map(document.getElementById('container'), { center: center, zoom: 13 }); //地址和经纬度之间进行转换服务 geocoder = new qq.maps.Geocoder(); //设置服务请求成功的回调函数 geocoder.setComplete(function(result) { map.setCenter(result.detail.location); var marker = new qq.maps.Marker({ map: map, position: result.detail.location }); //点击Marker会弹出反查结果 var info = new qq.maps.InfoWindow({ map: map }); qq.maps.event.addListener(marker, 'click', function() { info.open(); info.setContent('<div style="width:280px;height:100px;">' + result.detail.address + '</div>'); info.setPosition(result.detail.location); }); }); //若服务请求失败,则运行以下函数 geocoder.setError(function() { alert("出错了,请输入正确的经纬度!!!"); }); } function codeLatLng() { //获取输入框的经纬度 var input = document.getElementById("latLng").value; var latlngStr = input.split(",", 2); var lat = parseFloat(latlngStr[0]); var lng = parseFloat(latlngStr[1]); var latLng = new qq.maps.LatLng(lat, lng); //对指定经纬度进行解析 geocoder.getAddress(latLng); }
