前端之家收集整理的这篇文章主要介绍了jquery – 将自动填充列表中的国家/地区的Google地图限制为“INDIA,USA和UK”前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
代码无效.请告诉我确切的解决方
<script src="maps.googleapis.com/maps/api/…; type="text/javascript"></script>
<script type="text/javascript">
   function initialize() {
      var input = document.getElementById('searchTextField');
      /* restrict to multiple cities? */
      var options = {
          types: ['(cities)'],componentRestrictions: {country: ["usa","uk"]}
      };
      var autocomplete = new google.maps.places.Autocomplete(input,options); 
   }
   google.maps.event.addDomListener(window,'load',initialize);
</script>

UPDATE

2017年1月,Maps JavaScript API版本3.27中引入了多个国家/地区过滤自动完成功能

You can now restrict Autocomplete predictions to only surface from multiple countries. You can do this by specifying up to 5 countries in the componentRestrictions field of the AutocompleteOptions.

解决方法

首先,您无法从多个国家/地区进行过滤.这是一个已知问题 reported here.

然后,对于您的代码,您必须使用两个字符的字符串作为国家/地区代码

componentRestrictions can be used to restrict results to specific
groups. Currently,you can use componentRestrictions to filter by
country. The country must be passed as as a two character,ISO 3166-1
Alpha-2 compatible country code. 07001.

这是一个国家working sample我jsfiddled(取自Google samples list).
