如何初始化Google对象以在Meteor中使用自动填充地址表单？ https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform

我采用了基本方法并使用了提供的代码示例。我安装了HTTP包。模板显示表单但不将谷歌连接到服务。我假设对象没有初始化，需要帮助来解决这个问题。

Template.addressForm.rendered = function ({
            var placeSearch, autocomplete;
                var componentForm = {
                  street_number: 'short_name',
                  route: 'long_name',
                  locality: 'long_name',
                  administrative_area_level_1: 'short_name',
                  country: 'long_name',
                  postal_code: 'short_name'
                };

        function initialize() {
          // Create the autocomplete object, restricting the search
          // to geographical location types.
          autocomplete = new google.maps.places.Autocomplete(
              /** @type {HTMLInputElement} */(document.getElementById('autocomplete')),
              { types: ['geocode'] });
          // When the user selects an address from the dropdown,
          // populate the address fields in the form.
          google.maps.event.addListener(autocomplete, 'place_changed', function() {
            fillInAddress();
          });
        }

        function fillInAddress() {
          // Get the place details from the autocomplete object.
          var place = autocomplete.getPlace();

          for (var component in componentForm) {
            document.getElementById(component).value = '';
            document.getElementById(component).disabled = false;
          }

          // Get each component of the address from the place details
          // and fill the corresponding field on the form.
          for (var i = 0; i < place.address_components.length; i++) {
            var addressType = place.address_components[i].types[0];
            if (componentForm[addressType]) {
              var val = place.address_components[i][componentForm[addressType]];
              document.getElementById(addressType).value = val;
            }
          }
        }

        // Bias the autocomplete object to the user's geographical location,
        // as supplied by the browser's 'navigator.geolocation' object.
        function geolocate() {
          if (navigator.geolocation) {
            navigator.geolocation.getCurrentPosition(function(position) {
              var geolocation = new google.maps.LatLng(
                  position.coords.latitude, position.coords.longitude);
              var circle = new google.maps.Circle({
                center: geolocation,
                radius: position.coords.accuracy
              });
              autocomplete.setBounds(circle.getBounds());
            });
          }
        }
        });

HTML：

           <template name="addressForm">

            <div id="locationField">
                  <input id="autocomplete" placeholder="Enter your address"
                         onFocus="geolocate()" type="text">
                </div>

                <table id="address">
                  <tr>
                    <td class="label">Street address</td>
                    <td class="slimField"><input class="field" id="street_number"
                          disabled="true"></td>
                    <td class="wideField" colspan="2"><input class="field" id="route"
                          disabled="true"></td>
                  </tr>
                  <tr>
                    <td class="label">City</td>
                    <td class="wideField" colspan="3"><input class="field" id="locality"
                          disabled="true"></td>
                  </tr>
                  <tr>
                    <td class="label">State</td>
                    <td class="slimField"><input class="field"
                          id="administrative_area_level_1" disabled="true"></td>
                    <td class="label">Zip code</td>
                    <td class="wideField"><input class="field" id="postal_code"
                          disabled="true"></td>
                  </tr>
                  <tr>
                    <td class="label">Country</td>
                    <td class="wideField" colspan="3"><input class="field"
                          id="country" disabled="true"></td>
                  </tr>
                </table>
                </template>

appBody：

<head>
      <title>publishcity</title>
      <meta name="viewport" content="initial-scale=1.0, user-scalable=no">
        <meta charset="utf-8">

            height: 100%;
            margin: 0px;
            padding: 0px

你需要运行初始化函数在示例中，它在body onload hook上被调用

.active

你可能已经放弃了

将代码从函数中取出以便它可以运行，这可能就是让它工作所需要的所有
