如何将Google地点限制在特定城市 [英] How to restrict google places to specific city

问题描述

我目前只能将地点限制在一个国家/地区，但我也想将地点限制在一个特定的城市.有什么想法要实现吗?这是我当前的代码:

I am currently able to restrict places to only one country, but I also want to restrict on a specific city also. Any ideas how to achieve that? This is my current code:

var autocomplete,
                    options = {
                        types: ['geocode'],
                        componentRestrictions: {country: 'est'}
                    };
                autocomplete = new google.maps.places.Autocomplete(input, options);
                google.maps.event.addListener(autocomplete, 'place_changed', function () {
                    var place = autocomplete.getPlace().formatted_address;
                    $(input).attr('value',place);
                });

推荐答案

正如Luke所说，地点自动完成功能使您可以使用componentRestrictions仅按国家/地区进行过滤.

As Luke said the places autocomplete allows you to use componentRestrictions to filter by country only.

但是您可以对搜索请求字符串使用一些技巧. 只需在请求中添加带有城市名称的前缀即可.

But you can use a little trick with a search request string. Just add prefix with city name in request.

var prefix = 'Kyiv, ';

$(input).on('input',function(){
    var str = input.value;
    if(str.indexOf(prefix) == 0) {
        // string already started with prefix
        return;
    } else {
        if (prefix.indexOf(str) >= 0) {
            // string is part of prefix
            input.value = prefix;
        } else {
            input.value = prefix+str;
        }
    }
});
