Маркеры не отображаются на моей карте

Question

Я пытаюсь добавить маркеры в соответствии с событиями в базе данных и в случае события, происходящего в том же месте, добавив вкладку infoBubble для этого нового события. Я не могу понять, почему маркеры (и мои infoBubbles) не отображаются на моей карте.

Вот мой код:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=AIzaSyDpQfirqx48owNbdu6ZF01pTr3Lt-tjYQI&sensor=false"></script> 
<script type="text/javascript" src="http://google-maps-utility-library-v3.googlecode.com/svn/trunk/infobubble/src/infobubble.js"></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");

     var cord_pnumber = markers[i].getAttribute("ec_pnumber");

     var icon = location_icon; 

      for (var x = 0; x < markersArray.length; x++){ 
       if (markersArray[x].getPosition() == point){ 
        infobubblesArray[x].addTab(date, html); 
        break; 
       } 
       if (x < (markersArray.length -1)){continue} else{ 
        var newM = x+1; 
        markersArray[newM] = new google.maps.Marker({map: map, position: point, icon: icon});

    } 

function bindinfoBubble(marker, map, infoBubble) { 
    google.maps.event.addListener(marker, 'click', function() { 

    infoBubble.open(map, marker); 


    });

Answer 1

Я нашел решение, которое, кажется, работает (кроме вкладок, начиная в строке выше текущих вкладок) здесь является окончание петля для проверки на это:

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); 

Answer 2

Есть разные вопросы, большинство из всех for (var x = 0; x < markersArray.length; x++)

Вы создаете маркеры внутри этой петли, но изначально markersArray пуст, вы никогда не запустите этот цикл. Существует также опечатка, infobubbleArray должен быть infobubblesArray

Исправлен код:

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); 
     } 
    });
