Google Maps API v3：添加帶有多標記的折線沖突

Question

我正在使用Multimarker將帶有標簽的標記添加到自定義的Google地圖。 包含標簽的div使用onclick調用一個函數。 但是，如果我在地圖上添加折線，則onclick會停止工作。 我不知道為什么...

這是添加標記的代碼：

var fastMarkers = [];
var myLatlng = new google.maps.LatLng(70,-101);
var marker = new com.redfin.FastMarker(/*id*/1, myLatlng, ["<div onclick='test()'><span>mylabel</span></div>"], null);
fastMarkers.push(marker);                
new com.redfin.FastMarkerOverlay(map, fastMarkers);

這是折線：

 var linepathcoords = [
    new google.maps.LatLng(71, -103),
    new google.maps.LatLng(73, -107),
 ];

var linepath=new google.maps.Polyline({
  path:linepathcoords,
  strokeColor:"#ff0000",
  strokeOpacity:0.9,
  strokeWeight:2
});
//This next line is what's causing the onclick in the marker to stop working. Why?
linepath.setMap(map);
};

這是Multimarker的代碼：

    var divPixel = overlayProjection.fromLatLngToDivPixel(marker._latLng);
    textArray.push("<div style='position:absolute; left:");

    textArray.push("px;")
    if (marker._zIndex) {

    }
    textArray.push("'");

    }

    }
    textArray.push("</div>");

  this._div.parentNode.removeChild(this._div);

  this._divClassName = divClassName;
  this._zIndex = zIndex;
  this._leftOffset = leftOffset || 0;
  this._topOffset = topOffset || 0;

com.redfin.FastMarker.prototype.copy = function() {
  var htmlArray = this._htmlTextArray;
  var i = htmlArray.length;
  var htmlArrayCopy = new Array(i);
  while (i--) {
    htmlArrayCopy[i] = htmlArray[i];
  }
  return new com.redfin.FastMarker(this._id, latLng, htmlArrayCopy, this._divClassName, this._zIndex, this._leftOffset, this._topOffset);
}

附加信息：在添加折線之前，我可以使用Firefox中的“檢查”工具並選擇包含標簽的div和span。 但是添加折線后，div消失了（標簽在地圖上仍然可見，但是我無法單擊它，也無法使用檢查工具進行選擇。此外，添加折線后，我在Firefox中看到了“ “檢查”列表中，很多div突然出現“溢出：隱藏”，我不認為他們以前有過。這是一個線索嗎？如果我刪除折線，這也無濟於事。標簽仍然不起作用。例如，我可以添加多義線，將其刪除，添加標簽，然后標簽的onclick無效；或者我可以添加標簽，添加多義線，標簽的onclick停止工作，刪除折線，標簽' onclick仍然無法正常工作。）

提供下載的zip文件（2013-03-22）（ http://code.google.com/p/multimarker/ ）中包含的Multimarker js腳本與通過http訪問的js腳本之間存在差異： //multimarker.googlecode.com/svn/trunk/fast-marker-overlay/maps-v3/src/FastMarkerOverlay.js 。

通過http：//訪問的腳本說：

第24行：

panes.floatPane.appendChild(this._div);

代替

panes.overlayLayer.appendChild(this._div);

和第140行：

this.latLng

代替

latLng

我在下載的腳本中更改了這些內容，現在可以使用了！ 非常感謝geocodezip幫助我解決了這個問題！ 如果有什么辦法我可以給你這個信譽，請告訴我。 我是該網站的新手，我不確定它的工作原理...
