如何将Google自动填充结果限制为仅城市和国家/地区

2020/10/16 11:01 · javascript ·  · 0评论

我正在使用google autocomplete place javascript返回搜索框的建议结果,我只需要显示与输入字符有关的城市和国家/地区,但google api会提供很多我不需要的常规地方结果,所以将结果限制为仅显示城市和国家。

我正在使用以下示例:

<html>
<head>
<style type="text/css">
   body {
         font-family: sans-serif;
         font-size: 14px;
   }
</style>

<title>Google Maps JavaScript API v3 Example: Places Autocomplete</title>
<script src="http://maps.googleapis.com/maps/api/js?sensor=false&amp;libraries=places" type="text/javascript"></script>
<script type="text/javascript">
   function initialize() {
      var input = document.getElementById('searchTextField');
      var autocomplete = new google.maps.places.Autocomplete(input);
   }
   google.maps.event.addDomListener(window, 'load', initialize);
</script>

</head>
<body>
   <div>
      <input id="searchTextField" type="text" size="50" placeholder="Enter a location" autocomplete="on">
   </div>
</body>
</html>

您可以尝试国家/地区限制

function initialize() {

 var options = {
  types: ['(cities)'],
  componentRestrictions: {country: "us"}
 };

 var input = document.getElementById('searchTextField');
 var autocomplete = new google.maps.places.Autocomplete(input, options);
}

更多信息:

ISO 3166-1 alpha-2可用于将结果限制为特定组。当前,您可以使用componentRestrictions按国家/地区进行过滤。


该国家/地区必须作为两个字符与ISO 3166-1 Alpha-2兼容的国家/地区代码传递。


官方指定的国家/地区代码

<html>
<head>
<style type="text/css">
   body {
         font-family: sans-serif;
         font-size: 14px;
   }
</style>

<title>Google Maps JavaScript API v3 Example: Places Autocomplete</title>
<script src="https://maps.googleapis.com/maps/api/js?sensor=false&libraries=places" type="text/javascript"></script>
<script type="text/javascript">
   function initialize() {
      var input = document.getElementById('searchTextField');
      var options = {
        types: ['geocode'] //this should work !
      };
      var autocomplete = new google.maps.places.Autocomplete(input, options);
   }
   google.maps.event.addDomListener(window, 'load', initialize);
</script>

</head>
<body>
   <div>
      <input id="searchTextField" type="text" size="50" placeholder="Enter a location" autocomplete="on">
   </div>
</body>
</html>
var options = {
  types: ['geocode'] //this should work !
};
var autocomplete = new google.maps.places.Autocomplete(input, options);

对其他类型的引用:http : //code.google.com/apis/maps/documentation/places/supported_types.html#table2

尝试这个

<html>
<head>
<style type="text/css">
   body {
         font-family: sans-serif;
         font-size: 14px;
   }
</style>

<title>Google Maps JavaScript API v3 Example: Places Autocomplete</title>
<script src="https://maps.googleapis.com/maps/api/js?sensor=false&amp;libraries=places&region=in" type="text/javascript"></script>
<script type="text/javascript">
   function initialize() {
      var input = document.getElementById('searchTextField');
      var autocomplete = new google.maps.places.Autocomplete(input);
   }
   google.maps.event.addDomListener(window, 'load', initialize);
</script>

</head>
<body>
   <div>
      <input id="searchTextField" type="text" size="50" placeholder="Enter a location" autocomplete="on">
   </div>
</body>
</html>

http://maps.googleapis.com/maps/api/js?sensor=false&libraries=places “ type =” text / javascript“

更改为:“ region = in”(印度)

http://maps.googleapis.com/maps/api/js?sensor=false&libraries=places®ion=in ” type =“ text / javascript”

弗朗索瓦给出答案导致列出一个国家的所有城市。但是,如果要求列出一个国家或该国家/地区中的所有地区(城市+州+其他地区等),则可以通过更改类型来相应地过滤结果。

只列出该国的城市

 var options = {
  types: ['(cities)'],
  componentRestrictions: {country: "us"}
 };

列出全国所有城市,州和地区

 var options = {
  types: ['(regions)'],
  componentRestrictions: {country: "us"}
 };

列出所有机构,例如该国的餐馆,商店和办公室

  var options = {
      types: ['establishment'],
      componentRestrictions: {country: "us"}
     };

有关更多信息和选项,请访问:

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

希望这对某人有用

与接受的答案基本相同,但已更新为新类型和多个国家/地区限制:

function initialize() {

 var options = {
  types: ['(regions)'],
  componentRestrictions: {country: ["us", "de"]}
 };

 var input = document.getElementById('searchTextField');
 var autocomplete = new google.maps.places.Autocomplete(input, options);
}

使用'(regions)'代替'(cities)'允许按邮政编码以及城市名称进行搜索。

请参阅官方文档,表3:https :
//developers.google.com/places/supported_types

我一直在使用Google Autocomplete API,这是我发现的最佳解决方案,可以将您的结果限制为仅适用于以下国家/地区:

var autocomplete = new google.maps.places.Autocomplete(input, options);
var result = autocomplete.getPlace();
console.log(result); // take a look at this result object
console.log(result.address_components); // a result has multiple address components

for(var i = 0; i < result.address_components.length; i += 1) {
  var addressObj = result.address_components[i];
  for(var j = 0; j < addressObj.types.length; j += 1) {
    if (addressObj.types[j] === 'country') {
      console.log(addressObj.types[j]); // confirm that this is 'country'
      console.log(addressObj.long_name); // confirm that this is the country name
    }
  }
}

如果查看返回的结果对象,您会看到有一个address_components数组,其中包含几个代表地址不同部分的对象。在每个这些对象中,它将包含一个“类型”数组,并且在该“类型”数组中,您将看到与地址关联的不同标签,其中包括一个国家/地区的标签。

另外,由于您所在的国家/地区限制,您将需要缩放地图并居中!

只需使用缩放和中心参数即可!;)

function initialize() {
  var myOptions = {
    zoom: countries['us'].zoom,
    center: countries['us'].center,
    mapTypeControl: false,
    panControl: false,
    zoomControl: false,
    streetViewControl: false
  };

  ... all other code ...

}

我为自己找到了解决方案

var acService = new google.maps.places.AutocompleteService();
var autocompleteItems = [];

acService.getPlacePredictions({
    types: ['(regions)']
}, function(predictions) {
    predictions.forEach(function(prediction) {
        if (prediction.types.some(function(x) {
                return x === "country" || x === "administrative_area1" || x === "locality";
            })) {
            if (prediction.terms.length < 3) {
                autocompleteItems.push(prediction);
            }
        }
    });
});

此解决方案仅显示城市和国家。
