Question

我正在从您的示例中学习Google Maps API3。顺便说一句，他们非常有帮助。我有一个问题。在您的示例中，http://www.geocodezip.com/v3_GenericMapBrowser.asp?filename=flights090414.xml如何使IRS中的标记与折线一起关闭？但我希望保持能够使用您创建的xml文件中的数据单击标记的功能。我知道它在以下代码片段中的某处。非常感谢你的帮助。

// A function to create the marker and set up the event window function 

function createMarker(latlng,name,html,icon) {
var contentString = html;
var marker = new google.maps.Marker({
    position: latlng,
    icon: getMarkerImage(icon),
    shadow: iconShadow,
    map: map,
    title: name,
    zIndex: Math.round(latlng.lat()*-100000)<<5
    });
/*
google.maps.event.addListener(marker, 'click', function() {
    infowindow.setContent(contentString); 
    infowindow.open(map,marker);
    $("#tabs").tabs();
    });
*/
bindInfoWindow(marker, map, infowindow, contentString);
// save the info we need to use later for the side_bar
gmarkers.push(marker);
// add a line to the side_bar html
side_bar_html += '<a href="javascript:myclick(' + (gmarkers.length-1) + 

')">' + name + '<\/a><br>';
 }

// This function picks up the click and opens the corresponding info     

window
function myclick(i) {
google.maps.event.trigger(gmarkers[i], "click");
}


  function togglePoly(poly_num) {
    if (document.getElementById('poly'+poly_num)) {
       if (document.getElementById('poly'+poly_num).checked) {
          gpolys[poly_num].setMap(map);
       } else {
          gpolys[poly_num].setMap(null);
       }
    }
  } 


  function createClickablePolyline(poly, html, label, point, length) {
    gpolys.push(poly);
    var poly_num = gpolys.length - 1;
    if (!html) {html = "";}
    else { html += "<br>";}
length = length * 0.000621371192; // convert meters to miles
    html += "length="+length.toFixed(2)+" miles";
    // html += poly.getLength().toFixed(2)+" m; 

 "+(poly.getLength()*3.2808399).toFixed(2)+" ft; ";
    // html += (poly.getLength()*0.000621371192).toFixed(2)+" miles";
    var contentString = html;
    google.maps.event.addListener(poly,'click', function(event) {
      infowindow.setContent(contentString);
      if (event) {
         point = event.latLng;
      }
      infowindow.setPosition(point);
      infowindow.open(map);
      // map.openInfoWindowHtml(point,html); 
    }); 
    if (!label) {
      label = "polyline #"+poly_num;
    }
    label = "<a 



  href='javascript:google.maps.event.trigger(gpolys["+poly_num+"],\"
  click  \");'>"+label+"</a>";
    // add a line to the sidebar html
    side_bar_html += '<input type="checkbox" id="poly'+poly_num+'" 

  checked="checked" onclick="togglePoly('+poly_num+');">' + label + '<br 

  />';

  }

您还可以尝试循环gmarkers删除/添加侦听器。一些选项是google.maps.event.removeListener(listenerHandle);和google.maps.event.clearListeners(objectListened, 'event');
