データベース内のイベントに応じてマーカーを追加しようとしています。同じ場所でイベントが発生した場合は、その新しいイベントのタブをinfoBubbleに追加します。マーカー（およびinfoBubbles）がマップに表示されない理由がわかりません。

これが私のコードです：

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=AIzaSyDpQfirqx48owNbdu6ZF01pTr3Lt-tjYQI&sensor=false"></script>

<script type="text/javascript">

 var location_icon = new google.maps.MarkerImage('../images/FAFSA_Logo_icon.png');  
 var map;
 var markersArray= [];
 var infobubblesArray = [];
  function load() {

    map = new google.maps.Map(document.getElementById("map"), {
        center: new google.maps.LatLng(33.961586, -106.008728),
        zoom: 6,
        mapTypeId: 'roadmap'
    });



    downloadUrl("../site_parts/mapmysql.php", function(data) {
    var xml = data.responseXML;
    var markers = xml.documentElement.getElementsByTagName("marker");
    for (var i = 0; i < markers.length; i++) {
        var name = markers[i].getAttribute("event_name");
        var address = markers[i].getAttribute("venue_address");
        var city = markers[i].getAttribute("venue_city");

                    infobubblesArray[x].addTab(date, html);

さまざまな問題がありますが、とりわけ、for (var x = 0; x < markersArray.length; x++)

このループ内でマーカーを作成しますが、最初はmarkersArrayが空であるため、このループを実行することはありません。誤字脱字もあるinfobubbleArrayはずinfobubblesArray

固定コード:

downloadUrl("../site_parts/mapmysql.php", function(data) {

    var xml = data.responseXML;
    var markers = xml.documentElement.getElementsByTagName("marker");
    outer: for (var i = 0; i < markers.length; i++) {

           /* creation of the variables may stay here as it is */

            for (var x = 0; x < markersArray.length; x++){
                if (markersArray[x].getPosition().toString() == point.toString()){
                    infobubblesArray[x].addTab(date, html);                         
                    continue outer;
                }}

                var newM = markersArray.length;
                    markersArray[newM] = new google.maps.Marker({map: map, position: point});
                    infobubblesArray[newM] = new InfoBubble({maxWidth: 400, borderWidth: 2});
                    bindinfoBubble(markersArray[newM], map, infobubblesArray[newM])
                    infobubblesArray[newM].addTab(date, html);
        }
    });

機能しているように見える解決策を見つけました（現在のタブの上の行から始まるタブ以外に）それを確認するための終了ループは次のとおりです。

var x = 0;

while (x < (markersArray.length)){
  if (markersArray[x].getPosition().toString() == point.toString()){
  infobubblesArray[x].addTab(date, html);
  continue xmlLoop; /*to the outside loop for the xml sheet readthrough*/
  }x++;
}

var newM = markersArray.length;
markersArray[newM] = new google.maps.Marker({map: map, position: point, icon: icon});
infobubblesArray[newM] = new InfoBubble({maxWidth: 500, minHight: 600, borderRadius: 0});
bindinfoBubble(markersArray[newM], map, infobubblesArray[newM]);
infobubblesArray[newM].addTab(date, html);
