マップのレンダリングに問題があります。マップ上に2つのマーカーを動的に表示したい。ジオコード2つのアドレスと作成マップjs googlemaps api v3
地図はレンダリングされていますが、マーカーは表示されません。
はここでマップのための私のコードです：
<script type="text/javascript">
// When the window has finished loading create our google map below
google.maps.event.addDomListener(window, 'load', init);
function init() {
var delay = 100;
var infowindow = new google.maps.InfoWindow();
var mapOptions = {
// How zoomed in you want the map to start at (always required)
zoom: 11,
// The latitude and longitude to center the map (always required)
center: new google.maps.LatLng(51.507351, -0.127758), // New York
// How you would like to style the map.
// This is where you would paste any style found on Snazzy Maps.

私が正しくこれらのマーカーを表示することができますどのように？私はいくつかの間違いを犯した提案やフィードバックに感謝します。 setTimeout最初のパラメータは関数でなければならないよう
あなたはすべての関係のないコードを削除しようとするとちょうど2つのマーカーでマップを作成しましたか？あなたのコードにはたくさんのことがありますが、それを少し絞ることができます。 –
なぜ 'setTimeout（ 'geocodeAddress（"' +場所[nextAddress] + ''、theNext） '、遅延）; '？これはちょうど悪く見える！ 'geocodeAddress'は遅れて実行されるのではなく、' setTimeout'の評価時に実行されます –
ええ、それは問題でした。文字列で囲まれている理由は分かりません:)ありがとうそれ ！ – Robson
