我正在尝试获取我的位置。在html页面中,应该会显示mas,但默认地图上没有显示任何内容。为什么?有什么想法吗?如果没有看到您的实时代码,就很难看出是否有任何CSS可能会导致显示问题。但是,至少有两件事需要解决:
$( "#map-page" ).live( "pageinit", function()
{
// Default to Via Messina,Catania,IT when no geolocation support
var defaultLatLng = new google.maps.LatLng(37.530073, 15.112151);
if ( navigator.geolocation )
{
function success(pos)
{
// Location found, show coordinates on map
drawMap(new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude));
}
function fail()
{
drawMap(defaultLatLng); // Show default map
}
// Find users current position
navigator.geolocation.getCurrentPosition(success, fail, {enableHighAccuracy:true, timeout: 6000, maximumAge: 500000});
}
else
{
drawMap(defaultLatLng); // No geolocation support
}
function drawMap(latlng) {
var myOptions = {
zoom: 10,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(
document.getElementById("map-canvas"), myOptions);
// Add an overlay to the map of current lat/lng
var marker = new google.maps.Marker({
position: latlng,
map: map,
title: "Greetings!"
});
}
});
