現在，在Wordpress中使用GM API在Google地圖上顯示標記

Question

我是WordPress的新手。 但是我知道PHP的所有基礎知識。 我正在嘗試使用Google Map API將Google Map顯示到我的網站中。 我已經閱讀了這些教程，並且做的完全相同，但是標記未在WordPress上顯示。

我已經完成的工作：我已經通過template-maps的名稱創建了模板

這是我的代碼：

function initMap() {
    var map = new google.maps.Map(document.getElementById('map'), {
      center: {lat: -33.8688, lng: 151.2195},
      zoom: 13
    });
    var input = /** @type {!HTMLInputElement} */(
        document.getElementById('pac-input'));

    var types = document.getElementById('type-selector');
    map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);
    map.controls[google.maps.ControlPosition.TOP_LEFT].push(types);

    var autocomplete = new google.maps.places.Autocomplete(input);
    autocomplete.bindTo('bounds', map);

    var infowindow = new google.maps.InfoWindow();
    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) {
        window.alert("Autocomplete's returned place contains no geometry");
        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.setIcon(/** @type {google.maps.Icon} */({
        url: place.icon,
        size: new google.maps.Size(71, 71),
        origin: new google.maps.Point(0, 0),
        anchor: new google.maps.Point(17, 34),
        scaledSize: new google.maps.Size(35, 35)
      }));
      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(' ');
      }

      infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + 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']);
  }

HTML代碼：全部

  <input type="radio" name="type" id="changetype-establishment">
  <label for="changetype-establishment">Establishments</label>

  <input type="radio" name="type" id="changetype-address">
  <label for="changetype-address">Addresses</label>

  <input type="radio" name="type" id="changetype-geocode">
  <label for="changetype-geocode">Geocodes</label>
</div>
<div id="map-canvas"></div><!-- #map-canvas -->

Answer 1

您使用錯誤的ID

在這里，您將為id = map創建一個地圖

  var map = new google.maps.Map(document.getElementById('map'), {

但是您的map的div和CSS ID等於

   <div id="map-canvas">

   #map-canvas { width: 100%; height: 500px; }

那你應該用

 var map = new google.maps.Map(document.getElementById('map-canvas'), {
