我在地图上显示不同的标记,问题是有时(特别是当我重置网络服务器时)地图加载正确,它甚至显示点的阴影,但标记在地图上不显示/不可见。但是在随后的调用中,标记会正确显示(可能是 cached ,但不确定)。这种行为在所有浏览器中都是一致的,即 IE 6/7/8 、 Chrome 、 Firfox 3.5.6。
下面显示的 javascript 创建了标记。另一方面,由于标记可以有不同的尺寸,我需要先确定宽度和尺寸(否则它们看起来会变形)。
var imgTemp = new Image();
imgTemp.name = "img_" + i.toString();
imgTemp.src = groupMarkerUrl; //url to the actual image
point = new GLatLng(parseFloat(latitude), parseFloat(longitude));
var icon = new GIcon(G_DEFAULT_ICON);
icon.image = groupMarkerUrl;
icon.iconSize = new GSize(imgTemp.width, imgTemp.height); //Width x Height
icon.iconAnchor = new GPoint(14, 15);
icon.infoWindowAnchor = new GPoint(5, 1);
marker = new GMarker(point, icon);
map.setCenter(point, 13);
//build the information box
var htmlContent = "<div style=\"color:#000000\"><span style=\"font-weight:bold;\">" + title + "</span><br/>";
if (address != "") {
htmlContent += address + " ";
}
if (zipcode != "") {
htmlContent += "<br/>" + zipcode + ", ";
}
if (city != "") {
htmlContent += city;
}
if (telephone != "") {
htmlContent += "<br/>Tel : " + telephone;
}
if (fax != "") {
htmlContent += "<br/>Fax : " + fax;
}
htmlContent += "</div>";
map.addOverlay(marker);
markerKeys.push(stamp);
markers[stamp] = marker;
//Add legends with group markers one for each group
if (null == legends[groupId]) {
legends[groupId] = groupMarkerUrl;
var nbsp = document.createTextNode(" ");
var image = document.createElement("img");
image.setAttribute("src", groupMarkerUrl);
image.setAttribute("style", "margin-left:10px !important; border:\"0\";");
pushpinPnlConsole.appendChild(nbsp);
pushpinPnlConsole.appendChild(image);
pushpinPnlConsole.setAttribute("style", "display:block");
}
eval("GEvent.addListener(markers[stamp] , \"click\", function(){markers['" + stamp + "'].openInfoWindowHtml(windowHtmls['" + stamp + "']);});");
windowHtmls[stamp] = htmlContent;
opticianTBody.appendChild(row);
谢谢。
