Question

我正在尝试触发标记上的点击，但我有一个问题将数据传递给google.maps.event.trigger（）。我从map.data获取一个功能并将其传递给google.maps.event.trigger（），但infowindow没有打开。

google.maps.event.trigger（map.data，＆＃39;点击＆＃39;）有效，但这并不针对特定的标记。

任何建议或解决方案都会有所帮助。

google.maps.Data.MouseEvent - 回调的预期参数是一个具有单个属性的对象：feature（包含相关功能）。

触发click的{{1}} - 事件，并将此对象作为3参数传递给触发器：

map.data

要在回调中使用

获取要素（标记）的位置

 google.maps.event.trigger(map.data,'click',{feature:ourMarker});

（事件是传递给回调的参数）

演示：

event.feature.getGeometry().get()

function initialize() {


  var map = new google.maps.Map(document.getElementById('map-canvas'), {
      zoom: 5,
      center: new google.maps.LatLng(1, 1)
    }),
    infoWindow = new google.maps.InfoWindow({
      pixelOffset: new google.maps.Size(0, -36)
    });

  map.controls[google.maps.ControlPosition.TOP_CENTER].push(
    document.getElementById('ctrl')
  );

  map.data.addListener('click', function(event) {
    var feature = event.feature;
    infoWindow.setOptions({
      position: feature.getGeometry().get(),
      map: map,
      content: 'my id is ' + feature.getId()
    });
  });

  map.data.addGeoJson({
    "type": "FeatureCollection",
    "features": [{
      "type": "Feature",
      "id": 35,
      "geometry": {
        "type": "Point",
        "coordinates": [0, 0]
      }
    }, {
      "type": "Feature",
      "id": 36,
      "geometry": {
        "type": "Point",
        "coordinates": [1, 1]
      }
    }, {
      "type": "Feature",
      "id": 37,
      "geometry": {
        "type": "Point",
        "coordinates": [2, 2]
      }
    }]
  });
  window.showPopupbox = function(link) {
    var popupID = link.getAttribute("data-id");
    var ourMarker = map.data.getFeatureById(popupID);

    google.maps.event.trigger(map.data, 'click', {
      feature: ourMarker
    });

  }
}

google.maps.event.addDomListener(window, 'load', initialize);

html,
body,
#map-canvas {
  height: 100%;
  margin: 0px;
  padding: 0px
}
a {
  cursor: pointer;
}
ul {
  background: #fff;
}

在数据层上手动打开InfoWindow（GeoJSON）
