我正在使用谷歌地圖 - 方向和地理編碼。加載頁面時,地理編碼會放置一個標記。當用戶點擊提交按鈕時是否可以刪除該標記?如何刪除谷歌地理編碼點擊

下面是代碼:

var address = document.getElementById("address").textContent.replace(/\n/g, " "); 
geocoder.geocode({ 'address': address}, 
function(results, status) 
{ 
    if (status == google.maps.GeocoderStatus.OK) { 
    map.setCenter(results[0].geometry.location); 
    var marker = new google.maps.Marker({ 
     map: map, 
     position: results[0].geometry.location 
    }); 
    } 
    else 
    { 
    alert("Geocode was not successful for the following reason: " + status); 
    } 
}); 




var from = document.getElementById("from").value; 
var to = document.getElementById("to").value; 
var request = { 
    origin: from, 
    destination: to, 
    travelMode: google.maps.DirectionsTravelMode.DRIVING 
}; 
document.getElementById("map").style.width = "70%"; 
directionsService.route(request, function(response, status) { 
    if (status == google.maps.DirectionsStatus.OK) { 
    directionsDisplay.setDirections(response); 
    } 
});
