Javascript 将google maps api搜索的范围限制为仅一个区域

我想将我的谷歌地图的搜索结果限制在特定的latLngBounds范围内

-列出此addListener函数以更改边界：

google.maps.event.addListener(map, 'bounds_changed', function() {
var bounds = map.getBounds();
searchBox.setBounds(bounds);
});

我将其替换为：

var defaultBounds = new google.maps.LatLngBounds(
  new google.maps.LatLng(-33.8902, 151.1759),
  new google.maps.LatLng(-33.8474, 151.2631));

searchBox.setBounds(defaultBounds);

然而，它似乎不起作用。 是否有人可以为我指出正确的方向，将搜索结果限制在默认范围内，而不考虑当前的地图视点

以下是基于API的当前代码：

function initialize() {

var markers = [];
var map = new google.maps.Map(document.getElementById('map-canvas'), {
mapTypeId: google.maps.MapTypeId.ROADMAP
});

var defaultBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(30.9128292, -98.8563538),
new google.maps.LatLng(30.0964251, -97.9431152));
map.fitBounds(defaultBounds);

// Create the search box and link it to the UI element.
var input = /** @type {HTMLInputElement} */(
  document.getElementById('pac-input'));
map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);

var searchBox = new google.maps.places.SearchBox(
/** @type {HTMLInputElement} */(input));

// [START region_getplaces]
// Listen for the event fired when the user selects an item from the
// pick list. Retrieve the matching places for that item.
google.maps.event.addListener(searchBox, 'places_changed', function() {
var places = searchBox.getPlaces();

if (places.length == 0) {
  return;
}
for (var i = 0, marker; marker = markers[i]; i++) {
  marker.setMap(null);
}

// For each place, get the icon, place name, and location.
markers = [];
var bounds = new google.maps.LatLngBounds();
for (var i = 0, place; place = places[i]; i++) {
  var image = {
    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.
  var marker = new google.maps.Marker({
    map: map,
    icon: image,
    title: place.name,
    position: place.geometry.location
  });

  markers.push(marker);

  bounds.extend(place.geometry.location);
}

map.fitBounds(bounds);
});
// [END region_getplaces]

   searchBox.setBounds(defaultBounds);
}

google.maps.event.addDomListener(window, 'load', initialize);

这不是“更改”边界，而是在边界更改时侦听：

google.maps.event.addListener(map, 'bounds_changed', function() {
var bounds = map.getBounds();
searchBox.setBounds(bounds);
});

将

{bound:new LatLngBounds….}

传递给：

new google.maps.places.SearchBox(
/** @type {HTMLInputElement} */(input));

像这样的事情

让您的边界对象：

 var defaultBounds = new google.maps.LatLngBounds(
  new google.maps.LatLng(-33.8902, 151.1759),
  new google.maps.LatLng(-33.8474, 151.2631));

将其传递给承包商：

new google.maps.places.SearchBox(input, {bounds: defaultBounds});

的参考资料，我想我已经成功了，我的问题是我的LatLngBounds设置为西北偏东南，而不是西南偏东北。。我输入了正确的坐标，我的代码正常工作！
