推荐答案

您不能使用 Autocomplete 类做太多事情，至少不能使用任何记录的方法.您可以使用 自动完成服务 类和 getPlacePredictions 方法模仿标准自动完成的行为.

You can't do much with the Autocomplete class, at least not with any documented method. You can use the Autocomplete Service class and the getPlacePredictions method to mimic the behavior of the standard Autocomplete.

这意味着您将不得不构建自己的 UI 和行为，但它也为您提供了更大的灵活性，可以按照您想要的方式对其进行样式设置，并且它将允许您添加自定义地址很容易.

What that means is that you will have to build your own UI and behaviors, but it also gives you more flexibility to style it the way you want, and it will allow you to add your custom addresses easily.

这是一个简单的例子.它只是在顶部添加了两个自定义地址.您必须实现 2 个自定义地址背后的逻辑，因为当前单击它们时不会发生任何事情.但这还不是最棘手的部分，这个例子已经展示了你可以用它做什么.

Here is a quick example. It just adds two custom addresses on top. You will have to implement the logic behind the 2 custom addresses as currently nothing will happen when you click on them. But that's not the trickiest part, and this example shows already a lot of what you can do with it.

var autocompleteService, placesService, results, map;

function initialize() {

  results = document.getElementById('results');

  var mapOptions = {
    zoom: 5,
    center: new google.maps.LatLng(50, 50)
  };

  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

  // Bind listener for address search
  google.maps.event.addDomListener(document.getElementById('address'), 'input', function() {

    results.style.display = 'block';
    getPlacePredictions(document.getElementById('address').value);
  });

  // Show results when address field is focused (if not empty)
  google.maps.event.addDomListener(document.getElementById('address'), 'focus', function() {

    if (document.getElementById('address').value !== '') {

      results.style.display = 'block';
      getPlacePredictions(document.getElementById('address').value);
    }
  });

  // Hide results when click occurs out of the results and inputs
  google.maps.event.addDomListener(document, 'click', function(e) {

    if ((e.target.parentElement.className !== 'pac-container') && (e.target.parentElement.className !== 'pac-item') && (e.target.tagName !== 'INPUT')) {

      results.style.display = 'none';
    }
  });

  autocompleteService = new google.maps.places.AutocompleteService();
  placesService = new google.maps.places.PlacesService(map);
}

// Get place predictions
function getPlacePredictions(search) {

  autocompleteService.getPlacePredictions({
    input: search,
    types: ['establishment', 'geocode']
  }, callback);
}

// Get place details
function getPlaceDetails(placeId) {

  var request = {
    placeId: placeId
  };

  placesService.getDetails(request, function(place, status) {

    if (status === google.maps.places.PlacesServiceStatus.OK) {

      var center = place.geometry.location;
      var marker = new google.maps.Marker({
        position: center,
        map: map
      });

      map.setCenter(center);

      // Hide autocomplete results
      results.style.display = 'none';
    }
  });
}

// Place search callback
function callback(predictions, status) {

  // Empty results container
  results.innerHTML = '';

  // Place service status error
  if (status != google.maps.places.PlacesServiceStatus.OK) {
    results.innerHTML = '<div class="pac-item pac-item-error">Your search returned no result. Status: ' + status + '</div>';
    return;
  }

  // Build output with custom addresses
  results.innerHTML += '<div class="pac-item custom"><span class="pac-icon pac-icon-marker"></span>My home address</div>';
  results.innerHTML += '<div class="pac-item custom"><span class="pac-icon pac-icon-marker"></span>My work address</div>';

  // Build output for each prediction
  for (var i = 0, prediction; prediction = predictions[i]; i++) {

    // Insert output in results container
    results.innerHTML += '<div class="pac-item" data-placeid="' + prediction.place_id + '" data-name="' + prediction.terms[0].value + '"><span class="pac-icon pac-icon-marker"></span>' + prediction.description + '</div>';
  }

  var items = document.getElementsByClassName("pac-item");

  // Results items click
  for (var i = 0, item; item = items[i]; i++) {

    item.onclick = function() {

      if (this.dataset.placeid) {
        getPlaceDetails(this.dataset.placeid);
      }
    };
  }
}

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

大部分代码都有注释，所以它应该不言自明.

Most of the code is commented so it should speak for itself.
