谷歌街景与地方搜索相结合

Question

对于我目前正在进行的项目，我希望将Google地方的两个元素合并到谷歌街景视图中搜索，基本上强制位置（搜索后）查看为街道/全景。

谷歌有一个相当坚实的“基本”版本，但我似乎无法强迫它使用街景。任何见解都会很棒。

https://developers.google.com/maps/documentation/javascript/examples/places-searchbox

https://www.instantstreetview.com/ - 似乎做得很好，但我似乎找不到任何关于两者的文件。

Answer 1

结合SearchBox example的代码和StreetView example，应该给你第一次切割。

代码段：

// This example adds a search box to a map, using the Google Place Autocomplete
// feature. People can enter geographical searches. The search box will return a
// pick list containing a mix of places and predicted search terms.

// This example requires the Places library. Include the libraries=places
// parameter when you first load the API. For example:
// <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">
var panorama;
var clickedMarker;

function initAutocomplete() {
  var map = new google.maps.Map(document.getElementById('map'), {
    center: {
      lat: -33.8688,
      lng: 151.2195
    },
    zoom: 13,
    mapTypeId: 'roadmap'
  });
  var sv = new google.maps.StreetViewService();
  // Create the search box and link it to the UI element.
  var input = document.getElementById('pac-input');
  var searchBox = new google.maps.places.SearchBox(input);
  // map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);

  // Bias the SearchBox results towards current map's viewport.
  map.addListener('bounds_changed', function() {
    searchBox.setBounds(map.getBounds());
  });

  var markers = [];
  // Listen for the event fired when the user selects a prediction and retrieve
  // more details for that place.
  searchBox.addListener('places_changed', function() {
    var places = searchBox.getPlaces();

    if (places.length == 0) {
      return;
