Question

我想实现一个人们可以更改位置的功能。为此我想使用google places api。现在我想要的是一个搜索框，当有人输入一个城镇/地方时，它会搜索谷歌的地方并得出结果。一旦选择了位置，它将给我拉特和那个地方。没有地图可以吗？

感谢

Answer 1

您可以使用Google地图位置自动填充功能获取准确的地址，然后在成功获取地址后，您可以对其进行地理编码以获取lat和lng。

像这样：

function codeAddress(address) {
   geocoder.geocode({ 'address': address}, function(results, status) {
      if (status == 'OK') {
         alert(results[0].geometry.location); // This is the lat and lng
      } else {
         alert('Geocode was not successful for the following reason: ' + status);
      }
  });
}

请查看此工作示例：https://jsbin.com/pejagub/edit?html,js,output

我还在这里插入了代码片段，因为jsbin不能正常工作

＆＃13;

var placeSearch, autocomplete, geocoder;

function initAutocomplete() {
  geocoder = new google.maps.Geocoder();
  autocomplete = new google.maps.places.Autocomplete(
    (document.getElementById('autocomplete')), {
      types: ['geocode']
    });

  autocomplete.addListener('place_changed', fillInAddress);
}

function codeAddress(address) {
  geocoder.geocode({
    'address': address
  }, function(results, status) {
    if (status == 'OK') {
      // This is the lat and lng results[0].geometry.location
      alert(results[0].geometry.location);
    } else {
      alert('Geocode was not successful for the following reason: ' + status);
    }
  });
}

function fillInAddress() {
  var place = autocomplete.getPlace();

  codeAddress(document.getElementById('autocomplete').value);
}

＆＃13;

#autocomplete {
  width: 100%;
}

Answer 2

很抱歉迟到了。您可以在这里找到答案：

https://developers.google.com/maps/documentation/javascript/places-autocomplete#video

```

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

var input = document.getElementById('searchTextField');

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

```

不需要引用地图对象就可以通过边界。

谷歌没有地图放置搜索框？
