经过HTML5获取当前位置

// 当前位置
    function getLocation() {
        if (navigator.geolocation) {
            navigator.geolocation.getCurrentPosition(showPosition);
        }
        else {
            alert("暂时没法定位！");
        }
    }

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

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