google mapにて端末位置情報取得

function initMap() {
	if (navigator.geolocation) {
           // map apiのインポートのみでOK
           // この呼出自体は非同期
		navigator.geolocation.getCurrentPosition((position)=>{
			cb_initMap(position.coords.latitude,position.coords.longitude);
		},
		() => {
    //とれない場合デフォルト
        	cb_initMap(35.68944,139.69167);
        }
			

		);
	}
}
