我想用搜索框将谷歌地图添加到我的网站上（用标记（气球）显示地图上搜索到的地址），我们也可以点击地图中的任何地方（点击时必须去掉前一个标记，标记将出现在点击的位置（意味着地图上只应出现一个标记）。此外，我想将当前的纬度和经度（当前标记的确切位置）分别输入到两个不同的输入框中。

感谢任何帮助，提前感谢。

你可以试试这个。

var map = new google.maps.Map(document.getElementById('myMap'), {
        center: {lat: -34.397, lng: 150.644},

    });
 var myLatlng = new google.maps.LatLng(-34.397,150.644);
    marker = new google.maps.Marker({
        map: map,
        position: myLatlng,
        draggable: true,
        icon: mapIcon
    });
 var input = (document.getElementById('pac-input'));
    var autocomplete = new google.maps.places.Autocomplete(input);
    autocomplete.bindTo('bounds', map);

        var place = autocomplete.getPlace();
