Question

我需要在执行搜索后显示Google地图，但搜索框应该包含自动填充位置/地点。搜索框应该在搜索时具有自动填充位置，当单击时，应该相应地显示地图。

以下是代码：

<script>

        function initAutocomplete() {
            var map = new google.maps.Map(document.getElementById('map'), {
                center: {lat: -33.8688, lng: 151.2195},
                zoom: 13,
                mapTypeId: 'roadmap'
            });

            // Create the search box and link it to the UI element.
            var input = document.getElementById('pac-input');
            var searchBox = new google.maps.places.SearchBox(input);
            map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);

            // Bias the SearchBox results towards current map's viewport.
            map.addListener('bounds_changed', function () {
                searchBox.setBounds(map.getBounds());
            });

            var markers = [];
            // Listen for the event fired when the user selects a prediction and retrieve
            // more details for that place.
            searchBox.addListener('places_changed', function () {
                var places = searchBox.getPlaces();

                if (places.length == 0) {
                    return;
                }

                // Clear out the old markers.
                markers.forEach(function (marker) {
                    marker.setMap(null);
                });
                markers = [];

                // For each place, get the icon, name and location.
                var bounds = new google.maps.LatLngBounds();
                places.forEach(function (place) {
                    if (!place.geometry) {
                        console.log("Returned place contains no geometry");
                        return;
                    }
                    var icon = {
                        url: place.icon,
                        size: new google.maps.Size(71, 71),
                        origin: new google.maps.Point(0, 0),
                        anchor: new google.maps.Point(17, 34),
                        scaledSize: new google.maps.Size(25, 25)
                    };

                    // Create a marker for each place.
                    markers.push(new google.maps.Marker({
                        map: map,
                        icon: icon,
                        title: place.name,
                        position: place.geometry.location
                    }));

                    if (place.geometry.viewport) {
                        // Only geocodes have viewport.
                        bounds.union(place.geometry.viewport);
                    } else {
                        bounds.extend(place.geometry.location);
                    }
                });
                map.fitBounds(bounds);
            });
        }

</script>

<script src="https://maps.googleapis.com/maps/api/js?key
&libraries=places&callback=initAutocomplete"
        async defer></script>

这是另一个代码：

<input id="pac-input" class="controls" type="text" placeholder="Search" >
<div id="map"></div>

一种方法是将CSS中visibility元素的<div id="map"></div>属性设置为hidden。

#map {
  height: 100%;
  visibility: hidden;
}

然后，在搜索框places_changed事件处理程序的末尾，将地图元素的visibility设置为visible：

document.getElementById('map').style.visibility = 'visible';

另外，为了防止搜索框也不可见，我会从你的代码中删除这一行：

map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);

以下是a JSBin的工作示例。

我想在点击搜索后才显示谷歌地图
