此代码无效.请告诉我确切的解决方案
<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).
