使用「同步加載插件的方式」，引用各種插件，就能夠不建立地圖，直接獲取地圖數據。javascript

如下用IP定位作爲例子，詳細講述「如何不顯示地圖就獲取當前位置」。html

引入城市定位插件，更多插件與使用方法請見插件類總覽 java

<script type="text/javascript" src="http://webapi.amap.com/maps?v=1.3&key=您的Key&plugin=AMap.CitySearch"></script>

實例化城市定位web

var citysearch = new AMap.CitySearch();

定位結果，若是成功返回城市名稱，若是失敗返回錯誤信息api

citysearch.getLocalCity(function(status, result) {
            if (status === 'complete' && result.info === 'OK') {
                if (result && result.city && result.bounds) {
                    var cityinfo = result.city;
                    var citybounds = result.bounds;
                    document.getElementById('tip').innerHTML = '您當前所在城市：'+cityinfo;
                }
            } else {
                document.getElementById('tip').innerHTML = result.info;
            }
        });
