Google Places AutocompleteService filtering by cou

问题:

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.

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

I've tried:

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

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

Any suggestions?

回答1:

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);

You can specify types, and componentRestrictions using AutocompletionRequest. Here is an example -

var service = new google.maps.places.AutocompleteService();

    service.getPlacePredictions({ input: query, types: ['geocode'], 
                                componentRestrictions:{ country: 'us' } },
            function (predictions, status) {
                if (status == google.maps.places.PlacesServiceStatus.OK) {
                    var results = document.getElementById('results');
                    for (var i = 0, prediction; prediction = predictions[i]; i++) {
                        results.innerHTML += '<li>' + prediction.description + '</li>';
                    }
                }
            });

As outlined in the documentation reference, the Places Library AutocompleteService does not support AutocompleteOptions. If you think that this would be a valuable feature, please file a Places API - Feature Request.

You should use this code.

var options = {
    types: ['(cities)'],
    componentRestrictions: {country: ["in"]}
}
//Find From location    
var input= document.getElementById('input_box_city');
var fromAuto = new google.maps.places.Autocomplete(input, options);

Use this working Code

var input = document.getElementById("query_value");
var autocomplete = new google.maps.places.Autocomplete(input, {
  componentRestrictions: { country: "IN" },
  place_id: "YOUR_PLACE_ID"
});
google.maps.event.addListener(autocomplete, "place_changed", function() {
  var place = autocomplete.getPlace();
});
