谷歌地图听众打开外部链接个人信息窗口 [英] Google Maps listeners to open individual infowindow from external link
问题描述
我有一个谷歌从一个LINQ源正确映射图我的位置。我也可以单击该标记看到信息窗口中的内容。
与所有我的位置标在地图下面,我将展示标记的位置数据的列表。我想创建从该数据将打开地图相应标记的信息窗口的链接。我只能够得到所有的标记显示,当我加载页面,而不是单个的标记。
VAR currentlyOpenedInfoWindow = NULL;
功能init_map(map_canvas_id,纬度,经度,缩放,标记,infoWindowContents){
VAR myLatLng =新google.maps.LatLng(纬度,经度); VAR的选择= {
变焦:变焦,
中心:myLatLng,
mapTypeId设为:google.maps.MapTypeId.ROADMAP
};
VAR map_canvas提供=的document.getElementById(map_canvas_id); VAR地图=新google.maps.Map(map_canvas提供,期权); 如果(标记&放大器;&放大器; markers.length大于0){
VAR边界=新的google.maps.LatLngBounds(); 对于(VAR I = 0; I< markers.length;我++){
VAR的标记=新google.maps.Marker(标记[I]); marker.setMap(地图);
bounds.extend(marker.getPosition()); 如果(infoWindowContents&放大器;&放大器; infoWindowContents.length I标记)
createInfoWindow(地图,标记,infoWindowContents [I]);
} map.fitBounds(边界);
map.setCenter(bounds.getCenter());
}
}功能createInfoWindow(地图,标记,infoWindowProperties){
VAR信息=新google.maps.InfoWindow(infoWindowProperties); google.maps.event.addListener(标记,'点击',功能(){
如果(currentlyOpenedInfoWindow!= NULL)
currentlyOpenedInfoWindow.close(); info.open(地图,标记);
currentlyOpenedInfoWindow =信息; });}
的数据是从页我的背后code调用,并绘制成:
//循环每一个位置附近,并建立了JavaScript来放置标记
VAR的位置=新的List<串GT;();
VAR infoWindowContents =新的List<串GT;(); 数据视图nearbyLocations = schoolData_Record.DefaultView;
变种数= 1; 的foreach(在nearbyLocations DataRowView的位置)
{
locations.Add(的String.format(
@{{
标题:{0}
位置:新google.maps.LatLng({1},{2})
图标:../../Frontend/Images/v2/GoogleMaps/NumberToImageHandlerCS.ashx?number={3}
}}。
位置[名称],
位置[纬度],
位置[经度],
计数
)
);
infoWindowContents.Add(的String.format(
@{{
内容:< DIV CLASS = \\信息窗口\\>< B>存储#{0}< / B>< BR /> {1}< BR /> {2} {3} {4}< / DIV>中
}}。
位置[名称],
位置[的StreetAddress],
位置[市]
位置[国家]
位置[邮编code]
)
); 算上++;
} 变种locationsJson =[+的string.join(,,locations.ToArray())+];
变种overlayContentsJson =[+的string.join(,,infoWindowContents.ToArray())+]; //注入谷歌地图脚本
ClientScript.RegisterStartupScript(this.GetType(),谷歌地图初始化,
的String.Format(init_map('map_canvas提供',{0},{1},13,{2},{3});,纬度,经度,locationsJson,overlayContentsJson),真);
}
我有同样的烦恼 - 你需要在一个外壳打造的标志 - 这里是code我在我的项目中使用,你应该能够从这个共同破解它。
VAR指标=新的Array();
VAR markerLatLongs =新的Array();
VAR markerBounds =新的google.maps.LatLngBounds();
VAR信息窗口=新的Array();函数初始化(){
VAR的MapOptions = {
mapTypeId设为:google.maps.MapTypeId.ROADMAP
};
地图=新google.maps.Map(的document.getElementById(地图),
的MapOptions);
bPolygon.setMap(地图);
map.fitBounds(bLatLongBounds); createMarkers();
createInfoWindows();
}功能createMarkers(){
对于(VAR J = 0; J< sites.length; J ++)
{
VAR osRef =新OSRef(网站[J] .easting,网站[J] .northing);
VAR经纬度= osRef.toLatLng();
markerLatLongs [J] =新google.maps.LatLng(latLong.lat.toFixed(6),latLong.lng.toFixed(6))
markerBounds.extend(markerLatLongs [J]);
标记[J] =新google.maps.Marker({
位置:markerLatLongs [J]。
图:空,
标题:网站[J] .siteName
}); }}功能createInfoWindows(){
对于(VAR I = 0; I< sites.length;我++){
(函数(ⅰ){
信息窗口由[i] =新google.maps.InfoWindow({了maxWidth:200,含量:'&LT; DIV class=\"info-window-content\"><strong>'+sites[i].siteName+'</strong><p>'+sites[i].summary+'</p><a类=绿色链接的href =HTTP://+网站[I]的.url +'目标=_空白&GT;更多...&LT; / A&GT;&LT; / DIV&GT;'});
google.maps.event.addListener(标记[我],'点击',功能(E){
信息窗口[I]。开(地图,这一点);
});
})(一世);
}
}
I have a google map the plots my location correctly from a linq source. I can also click the marker to see the content within the info window.
Below the map with all my location marked, I show a list of the marked location data. I want to create a link from that data that will open the info window on the map for the corresponding marker. I have only been able to get all the markers to show when I load the page, but not for individual markers.
var currentlyOpenedInfoWindow = null;
function init_map(map_canvas_id, lat, lng, zoom, markers, infoWindowContents) {
var myLatLng = new google.maps.LatLng(lat, lng);
var options = {
zoom: zoom,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map_canvas = document.getElementById(map_canvas_id);
var map = new google.maps.Map(map_canvas, options);
if (markers && markers.length > 0) {
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < markers.length; i++) {
var marker = new google.maps.Marker(markers[i]);
marker.setMap(map);
bounds.extend(marker.getPosition());
if (infoWindowContents && infoWindowContents.length > i)
createInfoWindow(map, marker, infoWindowContents[i]);
}
map.fitBounds(bounds);
map.setCenter(bounds.getCenter());
}
}
function createInfoWindow(map, marker, infoWindowProperties) {
var info = new google.maps.InfoWindow(infoWindowProperties);
google.maps.event.addListener(marker, 'click', function() {
if (currentlyOpenedInfoWindow != null)
currentlyOpenedInfoWindow.close();
info.open(map, marker);
currentlyOpenedInfoWindow = info;
});
}
The data is called in from my code behind page and plotted as:
// Loop through each nearby location and build up the JavaScript to place the markers
var locations = new List<string>();
var infoWindowContents = new List<string>();
DataView nearbyLocations = schoolData_Record.DefaultView;
var count = 1;
foreach (DataRowView location in nearbyLocations)
{
locations.Add(string.Format(
@"{{
title: ""{0}"",
position: new google.maps.LatLng({1}, {2}),
icon: ""../../Frontend/Images/v2/GoogleMaps/NumberToImageHandlerCS.ashx?number={3}""
}}",
location["Name"],
location["Latitude"],
location["Longitude"],
count
)
);
infoWindowContents.Add(string.Format(
@"{{
content: ""<div class=\""infoWindow\""><b>Store #{0}</b><br />{1}<br />{2}, {3} {4}</div>""
}}",
location["Name"],
location["StreetAddress"],
location["city"],
location["State"],
location["Zipcode"]
)
);
count++;
}
var locationsJson = "[" + string.Join(",", locations.ToArray()) + "]";
var overlayContentsJson = "[" + string.Join(",", infoWindowContents.ToArray()) + "]";
// Inject the Google Maps script
ClientScript.RegisterStartupScript(this.GetType(), "Google Maps Initialization",
string.Format("init_map('map_canvas', {0}, {1}, 13, {2}, {3});", lat, lng, locationsJson, overlayContentsJson), true);
}
I had the same trouble - you need to create the markers in an enclosure - here is the code I used on my project you should be able to hack it together from this.
var markers = new Array();
var markerLatLongs = new Array();
var markerBounds = new google.maps.LatLngBounds( );
var infoWindows = new Array();
function initialize() {
var mapOptions = {
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'),
mapOptions);
bPolygon.setMap(map);
map.fitBounds( bLatLongBounds );
createMarkers();
createInfoWindows();
}
function createMarkers() {
for (var j = 0; j < sites.length; j++)
{
var osRef = new OSRef(sites[j].easting, sites[j].northing);
var latLong = osRef.toLatLng();
markerLatLongs[j] = new google.maps.LatLng(latLong.lat.toFixed(6),latLong.lng.toFixed(6))
markerBounds.extend(markerLatLongs[j]);
markers[j] = new google.maps.Marker({
position: markerLatLongs[j],
map: null,
title: sites[j].siteName
});
}
}
function createInfoWindows() {
for (var i = 0; i < sites.length; i++) {
(function(i){
infoWindows[i] = new google.maps.InfoWindow({maxWidth:200, content: '<div class="info-window-content"><strong>'+sites[i].siteName+'</strong><p>'+sites[i].summary+'</p><a class="green-link" href="http://'+sites[i].url+'" target="_blank">Read more...</a></div>'});
google.maps.event.addListener(markers[i], 'click', function(e) {
infoWindows[i].open(map, this);
});
})(i);
}
}
