在Google地图上获取当前位置 [英] Get Current Location On Google Map
问题描述
这是我第一次使用这个通用汽车API,并且有很多东西我都不知道't懂。
这是我的代码,我想要
var geocoder = new google.maps.Geocoder();
函数initialize(){
var latLng = new google.maps.LatLng(-7.7801502,110.3846387);
var map = new google.maps.Map(document.getElementById('mapCanvas'),{
zoom:15,
center:latLng,
mapTypeId:google.maps。 MapTypeId.ROADMAP
});
var marker = new google.maps.Marker({
位置:latLng,
标题:'Ambarrukmo Plaza Yogyakarta',
map:map,
可拖动:true
});
}
问题是,我想自动改变-7.7801502和110.3846387的值用户的当前位置。我可以这样做吗?
感谢您的帮助和解释。
另一个问题:
- >如果我要改变基于嵌入GPS的设备的价值,该怎么办?
您无法获取当前用户使用Google地图的位置。但是,如果您通过 Google Loader 获取Google地图,则可以使用google.loader.CurrentLocation 以获取基于IP的位置。
另外一种方法是使用 HTML5地理位置API 。$ b
function getLocation(){
if(navigator.geolocation){
navigator.geolocation.getCurrentPosition(showPosition);
} else {
alert(此浏览器不支持地理定位。);
}
}
function showPosition(position){
var lat = position.coords.latitude;
var lng = position.coords.longitude;
map.setCenter(new google.maps.LatLng(lat,lng));
}
I'm having some trouble when i want to get current location.
This is my first time using this GM API, and there are so much things i don't understand.
Here is my code, and i want
var geocoder = new google.maps.Geocoder();
function initialize() {
var latLng = new google.maps.LatLng(-7.7801502, 110.3846387);
var map = new google.maps.Map(document.getElementById('mapCanvas'), {
zoom: 15,
center: latLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker = new google.maps.Marker({
position: latLng,
title: 'Ambarrukmo Plaza Yogyakarta',
map: map,
draggable: true
});
}
The problem is, i want to change -7.7801502 and 110.3846387 value automatically based on user's current position. Can i do that?
Thanks before for your help and explanation.
Another question : -> What if i'm going to change those value based on a device embedded with GPS?
You can't get current user's location with Google Maps. However, if you get Google Maps with Google Loader, you can use the google.loader.CurrentLocation to get a location based on IP.
An other way is to use the HTML5 GeoLocation API.
function getLocation() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition);
} else {
alert("Geolocation is not supported by this browser.");
}
}
function showPosition(position) {
var lat = position.coords.latitude;
var lng = position.coords.longitude;
map.setCenter(new google.maps.LatLng(lat, lng));
}
