触发标记点击

Question

我正在使用 Fusion Table 和 Google 地图 API，想知道我是否可以在放置标记时自动触发事件。

目前我可以点击地图并获得一个自定义的信息窗口，但我想做同样的事情但是在地理编码和放置标记之后...我希望这会自动发生。

到目前为止，这是我的代码：

var FusionTableID = '<?php echo get_theme_mod( 'fusion_id' )?>';

var map = null;
var geocoder = null;
var marker = null;

function initialize() {
  geocoder = new google.maps.Geocoder();
  var local = new google.maps.LatLng(<?php echo get_theme_mod( 'lat-long' )?>);

  map = new google.maps.Map(document.getElementById('map-canvas'), {
    center: local,
    zoom: <?php echo get_theme_mod( 'zoom' )?>
  });
  // forces a refresh to from Fusion Tables
  //var and=' geometry does not contain "'+new Date().getTime()+'"';

  var layer = new google.maps.FusionTablesLayer({
    //suppressInfoWindows: true,
    query: {
     select: "col2\x3e\x3e0",
     from: FusionTableID,
     where: ""
      },
      options: {
        styleId: 2,
        templateId: 2
      },
      map: map
    });

    layer.setMap(map);

  google.maps.event.addListener(layer, "click", function(e) {

    var point = e.latLng.toUrlValue(6);
    var latlngStr = point.split(',', 2);
    var lat = parseFloat(latlngStr[0]);
    var lng = parseFloat(latlngStr[1]);
    var latlng = new google.maps.LatLng(lat, lng);
    if (marker && marker.setMap) marker.setMap(null);
         marker = new google.maps.Marker({
              position: latlng,
              map: map
          });

         console.log(e.row['objectid'].value);
         var tname = e.row['name'].value; // name
         var targetDist =  e.row['description'].value; // description
        // poplulate the infowindow
         e.infoWindowHtml = "<div class=\"grid-100\"><h2>"+tname+"</h2>"+targetDist+"<hr></div>";
    });  
}


function showAddress() {
    var address = document.getElementById('address').value;

    geocoder.geocode( { 'address': address}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
          if (marker && marker.setMap) marker.setMap(null);
          marker = new google.maps.Marker({
              map: map, 
              position: results[0].geometry.location
          });
           if (results[0].geometry.viewport) 
              map.fitBounds(results[0].geometry.viewport);

            // THIS DOESN'T WORK ****
            new google.maps.event.trigger( marker, 'click' );
      } else {
        alert("Geocode was not successful for the following reason: " + status);
      }
    });
}

感谢 geocodezip

It isn't really possible to "trigger" a click on a FusionTablesLayer (you can, but you basically need to replicate the information in the click event, which is painful), you can query the table an create your own infowindow on the marker though
