Question

我正在研究一个例子，我准备了一个谷歌地方搜索框，它通过自动完整工具给我直接输出到地图。但我想跟随更多搜索工具的类型

如果我在搜索框中写了一些东西并按键盘上的回车键，搜索框就可以了 2.i想要搜索框旁边的按钮，如果我在搜索框中输入了值，点击后会给我结果。示例：FIDDLE

1.如果我在搜索框中写了一些内容并按键盘输入键，搜索框应该可以使用

您可以使用google.maps。Geocoder将标记放置在地图上或定位地图。请参阅此example。

function selectFirstResult() {
    infowindow.close();
    var firstResult = $(".pac-container .pac-item:first").text();

    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({"address":firstResult }, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            var lat = results[0].geometry.location.lat(),
                lng = results[0].geometry.location.lng(),
                placeName = results[0].address_components[0].long_name,
                latlng = new google.maps.LatLng(lat, lng);

            moveMarker(placeName, latlng);
            $("input").val(firstResult);
        }
    });   
 }

2.i想要搜索框旁边的按钮，如果我在搜索框中输入了值，请点击它后给我结果。

您需要为该活动添加Event listener。通过调用addListener()在对象上注册事件处理程序来接收这些事件时，将执行代码。例如：

function initialize() {
  map = new google.maps.Map(document.getElementById('map'), options);
  searchBox = new google.maps.places.SearchBox(document.getElementById('searchbox'));
  google.maps.event.addListener(searchBox, 'places_changed', processPlacesSearch);
}

var button = document.getElementById('searchbutton');
var searchbox = document.getElementById('searchbox');

button.onclick = function () {
  var location = searchbox.value;
  processButtonSearch(location);
}

希望这有帮助！
