を使用して、マーカーは私はあなたがこのような何かを行う必要があります更新マーカー

Answer 1

ためにこのコードを使用していました。私はあなたが作りたいAJAX呼び出しを知らないので、私はそれを嘲笑し、私は例

//This is the fake ajax call we are supposed to call 
var fakeAjaxCall = function(success, error) { 
    var response = {lat: 59.327, lng: 18.067}; 
    window.setTimeout(success.bind(null, response), 1000); 
} 

//Our map object is already initialized, no marker is there yet. 
var map = new google.maps.Map(document.getElementById('map'), { 
    zoom: 13, 
    center: {lat: 59.325, lng: 18.070} 
}); 

//Here we make the ajax call. We expect a lat-lng response like the one from fake ajax call 
fakeAjaxCall(function success(responseMarker){ 
    var marker = new google.maps.Marker({ 
    position: responseMarker, 
    map: map, 
    title: 'Hello World!' 
    }); 
})
