我添加了一个带有两个标记的谷歌地图(我只是测试),代码是:
function load() {
var map = new GMap2(document.getElementById("map"));
var marker = new GMarker(new GLatLng(<%=coordinates%>));
var marker2 = new GMarker(new GLatLng(31.977211,35.951729));
var html="<%=maptitle%><br/>" +
"<%=text%>";
var html2="<img src='simplemap_logo.jpg' width='20' height='20'/> " +
"<%=maptitle%><br/>" +
"<%=text%>" + "Alper";
map.setCenter(new GLatLng(<%=coordinates%>), 5);
map.setMapType(G_HYBRID_MAP);
map.addOverlay(marker);
map.addOverlay(marker2);
map.addControl(new GLargeMapControl());
map.addControl(new GScaleControl());
map.addControl(new GMapTypeControl());
marker.openInfoWindowHtml(html);
marker2.openInfoWindowHtml(html2);
}
问题是,只有一个标记文本显示(内部有文本的白色三 Angular 形),另一个不可见,为什么? 另一件事,我有一个 map 表,如下所示:mapID、mapCoordinates、mapMarkerTitle、mapMarkerText,我可以检索该表,但我想要一种方法能够将其所有记录传递给我的javascript并为每个 map 创建一个标记我的 table 上有,我知道这是两个,但是有人可以建议或帮助我编写代码吗?因为我对 javascript 一无所知:D

最佳答案
回答您问题的第二部分:
i want a way to be able to pass all its records to my javascript and create a Marker for each Map i have in my table
我(作为示例 - 大约一年前编写)以下代码:
在代码隐藏中我有这样的东西(恐怕是c#):
[WebMethod]
public LatitudeLogitudeMessage[] GetPoints(string postCodes)
{
string[] postCodeArray = postCodes.Split(",".ToCharArray());
LatitudeLogitudeMessage[] pointArray =
new LatitudeLogitudeMessage[postCodeArray.Length];
int index = 0;
foreach (string postCode in postCodeArray)
{
pointArray[index] = GetPoint(postCode);
index++;
}
return pointArray;
}
LatitudeLogitudeMessage 是一个自定义类,如下所示:
public class LatitudeLogitudeMessage
{
public decimal? Latitude { get; set; }
public decimal? Longitude { get; set; }
public string Message { get; set; }
public string Details { get; set; }
public string Address { get; set; }
public LatitudeLogitudeMessage(string addressToFind)
{
Address = addressToFind;
Details = addressToFind.Replace(",", ",<br />");
}
}
GetPoint 方法基本上填写了这些详细信息。
在前面的代码中我有:
PageMethods.GetPoints(address, showPoints);
在后面的代码中调用 GetPoints 方法,并将结果传递给 showPoints:
function showPoints(latLongs)
{
GLog.write("Showing points");
var points = [];
var latLngBounds = new GLatLngBounds();
for (var i = 0; i < latLongs.length; i++)
{
if ("" == latLongs[i].Message)
{
points[i] = new GLatLng(latLongs[i].Latitude, latLongs[i].Longitude);
var marker =
new GMarker(points[i], {title: latLongs[i].Details, clickable: false});
map.addOverlay(marker);
latLngBounds.extend(points[i]);
}
else
{
GLog.write(latLongs[i].Message);
}
}
if (points.length > 1)
{
var bounds = new GBounds(points);
var center = new GLatLng(
(latLngBounds.getSouthWest().lat()
+ latLngBounds.getNorthEast().lat()) /2.,
(latLngBounds.getSouthWest().lng()
+ latLngBounds.getNorthEast().lng()) /2.);
var newZoom = map.getBoundsZoomLevel(latLngBounds, map.getSize());
map.setCenter(center, newZoom);
}
else
{
map.setCenter(points[0], defaultZoomLevel);
}
}
因此,这需要点数组,并迭代它们,创建一个标记,以列表中的第一项为中心(不聪明,但它对我有用)。
关于asp.net - Google map 上的多个标记,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/606515/
