谷歌地图标记不会显示（jQuery）

数据交换

我的网站上有一个谷歌地图，我在上面放了一个标记。

如果我在本地运行我的项目，标记会显示得很好，但是一旦我的网站上线，标记就不会显示，我不知道为什么（也没有显示在代码段中）。

#map {
  width: 100%;
  height: 450px;
  position: relative;
}

@media screen and (max-width: 768px) {
  #map {
    height: 200px;
  }
}

<div id="map"></div>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCefOgb1ZWqYtj7raVSmN4PL2WkTrc-KyA&callback=myMap"></script>

<script>
  var google;

  function init() {
    var myLatlng = new google.maps.LatLng(52.362487, 6.624294);

    var mapOptions = {
      // How zoomed in the map is
      zoom: 15,

      // The latitude and longitude to center the map 
      center: myLatlng
    };



    // Get the HTML DOM element that will contain your map
    // We are using a div with id="map" seen below in the <body>
    var mapElement = document.getElementById('map');

    // Create the Google Map using out element and options defined above
    var map = new google.maps.Map(mapElement, mapOptions);

    var addresses = ['Dollepret'];

    for (var x = 0; x < addresses.length; x++) {
      $.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address=' + addresses[x] + '&sensor=false', null, function(data) {
        var p = data.results[0].geometry.location
        var latlng = new google.maps.LatLng(p.lat, p.lng);
        new google.maps.Marker({
          position: latlng,
          map: map,
          label: {
            fontWeight: 'bold',
            fontSize: '14px',
            text: 'Dolle Pret'
          }
        });

      });
    }

  }
  google.maps.event.addDomListener(window, 'load', init);
</script>

地理编码

我在您的代码片段中收到此错误：

Mixed Content: The page at 'https://stackoverflow.com/questions/47577158/google-maps-marker-wont-show-jquery#' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://maps.googleapis.com/maps/api/geocode/json?address=Dollepret&sensor=false'. This request has been blocked; the content must be served over HTTPS.

如果我将该 URL 更改为 HTTPS，它将起作用（显示标记）。

（注意sensor不再需要该参数）

代码片段：

html, body {
height: 100%;
width: 100%;
margin: 0;
padding: 0px;
}
#map {
  width: 100%;
  height: 100%;
  position: relative;
}

/* @media screen and (max-width: 768px) {
  #map {
    height: 200px;
  }
