Google Maps API warning: NoApiKeys

function initMap() {
        var map = new google.maps.Map(document.getElementById('map'), {
          zoom: 8,
          center: {lat: -34.397, lng: 150.644}

 /*( 3959 * acos( cos( radians(-34.397) ) * cos( radians( sa.lat ) ) * cos( radians( sa.lng ) - radians(:lng) )

        }); 
        var geocoder = new google.maps.Geocoder();

        document.getElementById('submit').addEventListener('click', function() {
          geocodeAddress(geocoder, map);
        });
      }

      function geocodeAddress(geocoder, resultsMap) {
        var address = document.getElementById('address').value;
        geocoder.geocode({'address': address}, function(results, status) {
          if (status === 'OK') {
            resultsMap.setCenter(results[0].geometry.location);
            var marker = new google.maps.Marker({
              map: resultsMap,
              position: results[0].geometry.location
            });
          } else {
            alert('Geocode was not successful for the following reason: ' + status);
          }
        });
      }

#map {
        height: 100%;
      }
      /* Optional: Makes the sample page fill the window. */
      html, body {
        height: 100%;
        margin: 0;
        padding: 0;
      }
      #floating-panel {
        position: absolute;
        top: 10px;
        left: 25%;

答案

错误本身就是自我描述性的。只需单击该链接，它将重定向以下消息：

加载API的脚本元素没有API密钥。请确保包含有效的API密钥作为关键参数。您可以在Google API控制台上生成新的API密钥。

它还提供了关于Obtaining an API key指南的链接。

简而言之，您需要谷歌的API密钥才能运行此代码。因为你现在没有这个，所以你得到了警告。
