經過HTML5獲取當前位置

// 當前位置
    function getLocation() {
        if (navigator.geolocation) {
            navigator.geolocation.getCurrentPosition(showPosition);
        }
        else {
            alert("暫時沒法定位！");
        }
    }

    function showPosition(position) {
        alert(position.coords.latitude + " " + position.coords.longitude);
    }

    window.onload = function () {
        getLocation();
    }
