HTML5 地理位置定位（HTML5 Geolocation）原理及应用（调用GPS）
HTML5 Geolocation API 使用非常简单，基本调用方式如下：

判断一个标注点是否在多边形区域里

/**
			 * 计算一个点是否在多边形里
			 * @param {Object} pt 标注点
			 * @param {Object} poly 多边形数组
			 */
            function isInsidePolygon(pt, poly){
                for (var c = false, i = -1, l = poly.length, j = l - 1; ++i < l; j = i) 
                    ((poly[i].lat <= pt.lat && pt.lat < poly[j].lat) || (poly[j].lat <= pt.lat && pt.lat < poly[i].lat)) &&
                    (pt.lng < (poly[j].lng - poly[i].lng) * (pt.lat - poly[i].lat) / (poly[j].lat - poly[i].lat) + poly[i].lng) &&
                    (c = !c);
                return c;
            }
