复制代码 代码如下:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>根据地址查询经纬度</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <script type="text/javascript" src="http://api.map.baidu.com/api?v=1.3"></script>
</head>
<body style="background:#CBE1FF">
    <div style="width:730px;margin:auto;">  
        要查询的地址:<input id="text_" type="text" value="徐州古彭广场" style="margin-right:100px;"/>
        查询结果(经纬度):<input id="result_" type="text" />
        <input type="button" value="查询" onclick="searchByStationName();"/>
        <div id="container"
            style="position: absolute;
                margin-top:30px;
                width: 730px;
                height: 590px;
                top: 50;
                border: 1px solid gray;
                overflow:hidden;">
        </div>
    </div>
</body>
<script type="text/javascript">
    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 + "<br/><br/>经度:" + poi.point.lng + "<br/>纬度:" + poi.point.lat;
        var infoWindow = new BMap.InfoWindow("<p style='font-size:14px;'>" + content + "</p>");
        marker.addEventListener("click", function () { this.openInfoWindow(infoWindow); });
        // marker.setAnimation(BMAP_ANIMATION_BOUNCE); //跳动的动画
    });
    localSearch.search(keyword);
}
</script>
</html>

 

以上就是代码的全部内容了,小伙伴们可以直接使用在项目中哦,不用跟我说谢谢,请叫我雷锋大大~
