您可以使用 HTML5 的新地理位置。示例:http ://html5demos.com/geo
(取自上面的链接)
代码:
<script>
function success(position) {
var s = document.querySelector('#status');
if (s.className == 'success') {
// not sure why we're hitting this twice in FF, I think it's to do with a cached result coming back
return;
}
s.innerHTML = "found you!";
s.className = 'success';
var mapcanvas = document.createElement('div');
mapcanvas.id = 'mapcanvas';
mapcanvas.style.height = '400px';
mapcanvas.style.width = '560px';
document.querySelector('article').appendChild(mapcanvas);
var latlng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var myOptions = {
zoom: 15,
center: latlng,
mapTypeControl: false,
navigationControlOptions: {style: google.maps.NavigationControlStyle.SMALL},
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("mapcanvas"), myOptions);
var marker = new google.maps.Marker({
position: latlng,
map: map,
title:"You are here!"
});
}
function error(msg) {
var s = document.querySelector('#status');
s.innerHTML = typeof msg == 'string' ? msg : "failed";
s.className = 'fail';
// console.log(arguments);
}
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(success, error);
} else {
error('not supported');
}
</script>
至于数据库,我一直在走这条路,没有完美的解决方案,所有数据库只能给你大约 50 英里的准确度。
有了这个,您可以使用 Ajax 将位置数据推送到您的服务器。
