google-maps - Google 地方信息自动填充仅限澳大利亚的限制

Question

如何将 Google 地方信息仅限于澳大利亚？

这是我正在使用的代码:

function initialize() {

  var input = document.getElementById('searchTextField');
  var autocomplete = new google.maps.places.Autocomplete(input);
}

google.maps.event.addDomListener(window, 'load', initialize);

来自 autocomplete documentation :

Restrict the search to a specific country

Use the componentRestrictions option to restrict the autocomplete search to a particular country. The following code restricts the results to cities within France.

var input = document.getElementById('searchTextField');
var options = {
  types: ['(cities)'],
  componentRestrictions: {country: 'fr'}
};

autocomplete = new google.maps.places.Autocomplete(input, options);

对于澳大利亚，请使用“au”:

function initialize() {
  var options = {
    componentRestrictions: {country: 'au'}
  };

  var input = document.getElementById('searchTextField');
  var autocomplete = new google.maps.places.Autocomplete(input, options);
}

google.maps.event.addDomListener(window, 'load', initialize);

代码片段:

function initialize() {
  var options = {
    componentRestrictions: {country: 'au'}
  };

  var input = document.getElementById('searchTextField');
  var autocomplete = new google.maps.places.Autocomplete(input, options);
}

google.maps.event.addDomListener(window, 'load', initialize);
