javascript - 嵌入式谷歌地图未在 Firefox 中完全呈现

问题描述

我最近使用 Places Autocomplete 小部件设置了一个嵌入式谷歌地图，并注意到在 Firefox 中，UI 呈现一半时间或根本不呈现。有时我会得到一张空白的“灰色死亡地图”。该地图在 Chrome 上运行良好，性能问题为零。这是一个已知的问题？

我的代码基于 Google 文档中的 Places Autocomplete 示例。下面是 Maps js 开发人员文档中保存的小提琴。当我在 Firefox 中打开它时，它会延迟或不完整地呈现。如果渲染不完整，并且我触发了搜索事件，则 UI 将完全加载。

对此类问题的大多数回复建议刷新地图（google.maps.event.trigger(map, 'resize');）或确保正确设置地图选项（缩放和居中）。我研究了这些路径。就像我说的，它在 Chrome 中效果很好，在 Firefox 中效果不佳。

// 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">

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    center: {lat: -33.8688, lng: 151.2195},
    zoom: 13
  });
  var card = document.getElementById('pac-card');
  var input = document.getElementById('pac-input');
  var types = document.getElementById('type-selector');
  var strictBounds = document.getElementById('strict-bounds-selector');

  map.controls[google.maps.ControlPosition.TOP_RIGHT].push(card);

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

  // Bind the map's bounds (viewport) property to the autocomplete object,
  // so that the autocomplete requests use the current map bounds for the
  // bounds option in the request.
  autocomplete.bindTo('bounds', map);

  // Set the data fields to return when the user selects a place.
  autocomplete.setFields(
      ['address_components', 'geometry', 'icon', 'name']);

  var infowindow = new google.maps.InfoWindow();
  var infowindowContent = document.getElementById('infowindow-content');
  infowindow.setContent(infowindowContent);
  var marker = new google.maps.Marker({
    map: map,
    anchorPoint: new google.maps.Point(0, -29)
  });

  autocomplete.addListener('place_changed', function() {
    infowindow.close();
    marker.setVisible(false);
    var place = autocomplete.getPlace();
    if (!place.geometry) {
      // User entered the name of a Place that was not suggested and
      // pressed the Enter key, or the Place Details request failed.
      window.alert("No details available for input: '" + place.name + "'");
      return;
    }

    // If the place has a geometry, then present it on a map.
    if (place.geometry.viewport) {
      map.fitBounds(place.geometry.viewport);
    } else {
      map.setCenter(place.geometry.location);
      map.setZoom(17);  // Why 17? Because it looks good.
    }
    marker.setPosition(place.geometry.location);
    marker.setVisible(true);

    var address = '';
    if (place.address_components) {
      address = [
        (place.address_components[0] && place.address_components[0].short_name || ''),
        (place.address_components[1] && place.address_components[1].short_name || ''),
        (place.address_components[2] && place.address_components[2].short_name || '')
      ].join(' ');
    }

    infowindowContent.children['place-icon'].src = place.icon;
    infowindowContent.children['place-name'].textContent = place.name;
    infowindowContent.children['place-address'].textContent = address;
    infowindow.open(map, marker);
  });

  // Sets a listener on a radio button to change the filter type on Places
  // Autocomplete.
  function setupClickListener(id, types) {
    var radioButton = document.getElementById(id);
    radioButton.addEventListener('click', function() {
      autocomplete.setTypes(types);
    });
  }

  setupClickListener('changetype-all', []);
  setupClickListener('changetype-address', ['address']);
  setupClickListener('changetype-establishment', ['establishment']);
  setupClickListener('changetype-geocode', ['geocode']);

  document.getElementById('use-strict-bounds')
      .addEventListener('click', function() {
        console.log('Checkbox clicked! New state=' + this.checked);
        autocomplete.setOptions({strictBounds: this.checked});
      });
}
