我正在使用 Google Maps API 编写 JavaScript 代码.
I am writing JavaScript code using Google Maps API.
map = new google.maps.Map2(document.getElementById("map_canvas"));
map.setCenter(new google.maps.LatLng(37.4419, -122.1419), 13);
以上代码将地图画布的默认位置设置为帕洛阿尔托.
The above code sets the default location of the map canvas to Palo Alto.
如何编写脚本,让setCenter函数自动指向客户端的当前位置?
How can we write the script in such a way that the setCenter function automatically points to the current location of the client?
您可以在支持它的浏览器中使用 HTML5 GeoLocation API.
You can use the HTML5 GeoLocation API in browsers that support it.
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(success, error);
} else {
alert('geolocation not supported');
}
function success(position) {
alert(position.coords.latitude + ', ' + position.coords.longitude);
}
function error(msg) {
alert('error: ' + msg);
}
