代码如下:

要查询的地址：
查询结果(经纬度)：

style="position: absolute;
margin-top:30px;
width: 730px;
height: 590px;
top: 50;
border: 1px solid gray;
overflow:hidden;">




var map = new BMap.Map("container");
map.centerAndZoom("徐州", 12);
map.enableScrollWheelZoom(); //启用滚轮放大缩小，默认禁用
map.enableContinuousZoom(); //启用地图惯性拖拽，默认禁用
map.addControl(new BMap.NavigationControl()); //添加默认缩放平移控件
map.addControl(new BMap.OverviewMapControl()); //添加默认缩略地图控件
map.addControl(new BMap.OverviewMapControl({ isOpen: true, anchor: BMAP_ANCHOR_BOTTOM_RIGHT })); //右下角，打开
var localSearch = new BMap.LocalSearch(map);
localSearch.enableAutoViewport(); //允许自动调节窗体大小
function searchByStationName() {
map.clearOverlays();//清空原来的标注
var keyword = document.getElementById("text_").value;
localSearch.setSearchCompleteCallback(function (searchResult) {
var poi = searchResult.getPoi(0);
document.getElementById("result_").value = poi.point.lng + "," + poi.point.lat;
map.centerAndZoom(poi.point, 13);
var marker = new BMap.Marker(new BMap.Point(poi.point.lng, poi.point.lat)); // 创建标注，为要查询的地方对应的经纬度
map.addOverlay(marker);
var content = document.getElementById("text_").value + "

经度：" + poi.point.lng + "
纬度：" + poi.point.lat;
var infoWindow = new BMap.InfoWindow("

" + content + "

");
marker.addEventListener("click", function () { this.openInfoWindow(infoWindow); });
// marker.setAnimation(BMAP_ANIMATION_BOUNCE); //跳动的动画
});
localSearch.search(keyword);
}
