我对 Google Maps Api 和 jQuery 有一个大问题。我需要从 XML 文件中获取标记,并在地图上显示。
这是带有地图的页面: http: //szymonnosal.pl/sandbox/bsk/
我的代码:
我初始化地图:
var mapa; // obiekt globalny
var dymek; // okno z informacjami
var networks = [];
var locations = [];
function mapaStart()
{
var wspolrzedne = new google.maps.LatLng(50.0157021545812, 19.9094574787954);
var opcjeMapy = {
zoom: 15,
center: wspolrzedne,
mapTypeId: google.maps.MapTypeId.ROADMAP,
disableDefaultUI: true,
navigationControl: true,
mapTypeControl: true
};
mapa = new google.maps.Map(document.getElementById("mapka"), opcjeMapy);
dymek = new google.maps.InfoWindow();
loadNetworks();
google.maps.event.addListener(mapa,'click',function(){
resetLocations();
});
}
在 loadNetwork() 我从 XML 文件加载标记,我使用 jQuery:
function loadNetworks()
{
$.get('net.xml',function(xml){
$(xml).find("network").each(function(){
var lat = parseFloat($(this).find("lat").text());
var lon = parseFloat($(this).find("lon").text());
var icon_url = $(this).find("icon").text();
var SSID = $(this).find("SSID").text();
var BSSID = $(this).find("BSSID").text();
var AuthMode = $(this).find("AuthMode").text();
var Frequency = $(this).find("Frequency").text();
//alert(lat+' '+lon+' '+icon_url+' '+SSID+' '+BSSID+' '+AuthMode+' '+Frequency);
var marker = addNetwork(lat,lon,icon_url,SSID,BSSID,AuthMode,Frequency);
alert(marker.txt); // <- marker is correct object, because in alert pop-up is text from marker.
});
});
}
在 addNetwork 中,我在地图上添加标记。
function addNetwork(lat,lon,icon_url,SSID,BSSID,AuthMode,Frequency)
{
var size = new google.maps.Size(30,23);
var start_point = new google.maps.Point(0,0);
var start_hook = new google.maps.Point(15,12);
var icon = new google.maps.MarkerImage(icon_url, size, start_point, start_hook);
var marker = new google.maps.Marker(
{
position: new google.maps.LatLng(lat,lon),
title: BSSID,
icon: icon,
map: mapa
}
);
marker.txt = 'BSSID: '+BSSID+'<br/>SSID: '+SSID+'<br />AuthMode: '+AuthMode+'<br />Frequency: '+Frequency;
google.maps.event.addListener(marker,"click",function()
{
dymek.setPosition(marker.getPosition());
dymek.setContent(marker.txt);
dymek.open(mapa);
});
return marker;
}
如果我使用其他函数加载 XML,它是正确的:
function loadNetworks()
{
jx.load('getNetwork.php', function(xml)
{
var markery = xml.getElementsByTagName("network");
for(var i=0; i<markery.length; i++)
{
var lat = parseFloat(markery[i].attributes.getNamedItem("lat").nodeValue);
var lon = parseFloat(markery[i].attributes.getNamedItem("lon").nodeValue);
var ikona_url = markery[i].attributes.getNamedItem("ikona").nodeValue;
var SSID = markery[i].attributes.getNamedItem("SSID").nodeValue;
var BSSID = markery[i].attributes.getNamedItem("BSSID").nodeValue;
var AuthMode = markery[i].attributes.getNamedItem("AuthMode").nodeValue;
var Frequency = markery[i].attributes.getNamedItem("Frequency").nodeValue;
var marker = addNetwork(lat,lon,ikona_url,SSID,BSSID,AuthMode,Frequency);
}
alert('Wczytano '+markery.length+' markerów z pliku networks.xml');
},'xml','get');
}

你有什么想法,我的代码有什么问题吗?
