将Google街景与地点搜索相结合

标签: javascript google-maps google-api google-street-view

对于我当前正在从事的项目,我希望将Google地点的两个元素都纳入Google街景搜索中,从本质上强制将位置(搜索后)显示为街道/全景。

Google有一个非常可靠的“基本”版本,但我似乎不能强迫它使用街景。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,但是我似乎找不到关于这两者的任何文档。

SearchBox example中的代码与StreetView example合并在一起,应该可以使您初见端倪。

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;

  });
  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.
