Google Places AutocompleteService按国家/地区过滤 [英] Google Places AutocompleteService filtering by country

问题描述

我正在设置一个自定义自动填充字段，在其中显示Google地方信息中的位置以及数据库中与搜索查询匹配的事件.因此，我使用Google Places Autocomplete Service来获取查询预测，而不是直接将Places Autocomplete插入我的文本字段中.

I'm setting up a custom autocomplete field where I show locations from Google Places and events from my database that match the search query. For this reason, I'm using the Google Places Autocomplete Service to get the query predictions rather than plugging in the Places Autocomplete directly into my textfield.

问题是我不知道如何使用自动完成"服务按国家/地区过滤地点自动填充"建议.

The problem is I can't figure out how to filter Places Autocomplete suggestions by country using the AutoComplete service.

我尝试过:

var service = new google.maps.places.AutocompleteService(null, {
        types: ['cities'],
        componentRestrictions: {country: "au"}
    });

，但仍显示来自德国和法国的自动填充选项:(

but it still shows autocomplete options from Germany and France:(

有什么建议吗?

推荐答案

调用服务时需要传递限制，而不是在创建服务时传递限制.在这里:

You need to pass the restrictions when you call the service, not when you create it. Here:

//create service
service = new google.maps.places.AutocompleteService();

//perform request. limit results to Australia
var request = {
    input: 'Brisbane',
    componentRestrictions: {country: 'au'},
};
service.getPlacePredictions(request, callback);
