getLocation(address:String) none 根据指定的地址进行解析。
setComplete(callback:Function) none

设置检索成功后的回调函数,参数对象:{type:ServiceResultType.GEO_INFO,detail:Object. <GeoInfo>}

setError(callback:Function) none 设置检索失败后的回调函数。

实例

例子 1:

本示例中,设置地址解析服务属性

JavaScript
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);
