我无法渲染锚定有多个标记的Google地图infowindow。多个标记,单个信息窗口,锚定在地图底部
我使用MVC 3和JavaScript来渲染地图,地图呈现良好,以及相关的信息窗口。但我希望信息窗口显示在地图的底部,而不是相对于标记。根据用于搜索的国家,每张地图的起点可能会有所不同。我的JavaScript以下(这是工作)>我只是不知道如何改变信息窗口:
function initializeMap() {
var countryID = $("#CountryID :selected").val();
var cityID = $("#cities :selected").val();
var regionID = $("#regions :selected").val();
var locationtypeID = $("#LocationTypeID :selected").val();
var filtertype = $("#filtertype").val();
var latlng;
$.ajax({
type: "GET",
url: "/ajaxcalls/getCentre",
data: "cid=" + countryID,
datatype: "json",
success: function (result) {
var gpscoords = (result).split(",");
latlng = new google.maps.LatLng(gpscoords[0], gpscoords[1]);
},
error: function (req, status, error) {
}
});
var myOptions = {
zoom: 7,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
$.ajax({
type: "GET",
url: "/ajaxcalls/getmarkers",
data: "cid=" + countryID + "&rid=" + regionID + "&xid=" + cityID + "&tid=" + locationtypeID + "&filterType=" + filtertype,
datatype: "json",
success: function (result) {
var infowindow = null;
infowindow = new google.maps.InfoWindow({
content: "holding..."
});
$.each(result, function (i, item) {
var gpscoords = (item.GPSCoOrds.toString()).split(",");
var mpos = new google.maps.LatLng(gpscoords[1], gpscoords[0]);
var markerobject = "";
if (item.LocationTypeID == 2) {
markerobject = "atm.png";
}
else {
markerobject = "bank.png";
}
marker = new google.maps.Marker({
map: map,
position: mpos,
draggable: false,
icon: "/content/mapicons/" + markerobject,
title: item.Designation.toString() + " " + item.Address.toString()
});
google.maps.event.addListener(marker, 'mouseover', function() {
var windowcontent = "<div>Site Name: ";
windowcontent = windowcontent + item.Designation + "</div>";
windowcontent = windowcontent + "<div>Address: " + item.Address + "</div>";
windowcontent = windowcontent + "<div>Contact Number: " + item.contactNumber + "</div>";
windowcontent = windowcontent + "<div>Branch Type: " + item.BranchType + "</div>";
windowcontent = windowcontent + "<div>Network Provider: " + item.NetworkProvider + "</div>";
windowcontent = windowcontent + "<div>Network Capacity: " + item.NetworkCapacity + "</div>";
infowindow.setContent(windowcontent);
infowindow.open(map, this);
});
});
},
error: function (req, stats, error) {
alert(error);
}
});
}
$(document).ready(function() {
$("#mapupdater").click(function() {
initializeMap();
});
});
任何帮助,将不胜感激。
Postition属性的问题在于它仍然是一个LatLng对象。如果您滚动地图或移动地图,infowindow就会移开,因为此时地图上可能不会显示latlng。我的理解是否正确? –
是的,所以您需要在地图边界发生变化时拥有事件侦听器,以重绘任何打开的infowindows。 – duncan
感谢所有的回复,我刚刚创建了一个静态浮动div,并使用ajax调用来直接更新数据库中的信息。 –
