使用markermanager.js从API2迁移到API3

Question

我将地图API2更新为API3时遇到问题。

我无法使用markermanager.js库从JSON文件导入/显示标记。

我收到了错误：未捕获的TypeError：无法读取属性＆＃39; lng＆＃39;未定义的

我将函数GDownloadUrl从小文件

更改为jx.load

    <script type="text/javascript" src="http://www.openjs.com/scripts/jx/jx.js"></script> 

它工作正常。

来源js代码：

    var mapa;
    var manager;
    var markery = [];

            // wspólne cechy ikon
            var rozmiar = new google.maps.Size(15,15);
            var rozmiar_cien = new google.maps.Size(59,32);
            var punkt_startowy = new google.maps.Point(8,8);
            var punkt_zaczepienia = new google.maps.Point(8,8);

            // ikonki
            var ikona = new google.maps.MarkerImage("/test/marker.png", rozmiar, punkt_startowy, punkt_zaczepienia);
            var cien = new google.maps.MarkerImage("", rozmiar_cien, punkt_startowy, punkt_zaczepienia);

    function mapaStart()
    {
            // tworzymy mapę
            var wspolrzedne = new google.maps.LatLng(37.642647000000004,-122.272251);
            var opcjeMapy = {

                mapTypeId: google.maps.MapTypeId.ROADMAP
            };
            mapa = new google.maps.Map(document.getElementById("mapka"), opcjeMapy); 

            manager = new MarkerManager(mapa); //,{maxZoom: 19});
            pobierzMarkery();
    }

    function pobierzMarkery()
    {
        //GDownloadUrl('/test/markery.php',function(dane,kodOdpowiedzi)
        //Change GDownloadUrl to microAjax
        jx.load('/test/markery.php',function(dane,kodOdpowiedzi)
        {   
            var wyniki = eval('('+dane+')');
            var tablicaMarkerow = [];
            for(var i=0; i<wyniki['markery'].length; i++)
            {
                tablicaMarkerow.push(utworzMarker(wyniki['markery'][i]['id'],wyniki['markery'][i]['lat'], wyniki['markery'][i]['lng'], wyniki['markery'][i]['nazwa']));

            }
            manager.addMarkers(tablicaMarkerow,5,19);   //markers,min zoom, max zoom
            manager.refresh();

        });
    }

    function utworzMarker(id,lat,lng,tekst)
    {   
        var punkt = new google.maps.LatLng(lat,lng);
        var marker = new google.maps.Marker(opcje);
        var opcje = 
        {
            position: punkt,
            map: mapa,
            title: tekst,
            icon: ikona,
            shadow: cien
        }
        marker.tekst = tekst;
        markery[id] = marker;
        google.maps.event.addDomListener(marker,'click',function()
        {
            marker.openInfoWindowHtml(marker.tekst);
        });
        return marker;
    }

我使用谷歌库：

    <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> 
    <script type="text/javascript" src="http://google-maps-utility-library-v3.googlecode.com/svn/tags/markermanager/1.0/src/markermanager.js"></script>

HTML

   <div id='mapka' style='width: 400px; height: 500px; border: 1px solid black; background: gray;'></div>

Answer 1

您没有正确初始化google.maps.Marker，您需要先创建MarkerOptions对象并将其传递给标记构造函数（或将匿名对象传递给构造函数。所以：

function utworzMarker(id,lat,lng,tekst)
{   
    var punkt = new google.maps.LatLng(lat,lng);
    var marker = new google.maps.Marker(opcje);
    var opcje = 
    {
        position: punkt,
        map: mapa,
        title: tekst,
        icon: ikona,
        shadow: cien
    }
    marker.tekst = tekst;
    markery[id] = marker;
    google.maps.event.addDomListener(marker,'click',function()
    {
        marker.openInfoWindowHtml(marker.tekst);
    });
    return marker;
}

应该是：

function utworzMarker(id,lat,lng,tekst)
{   
    var punkt = new google.maps.LatLng(lat,lng);
    var opcje = 
    {
        position: punkt,
        map: mapa,
        title: tekst,
        icon: ikona,
        shadow: cien
    }
    var marker = new google.maps.Marker(opcje);
    marker.tekst = tekst;
    markery[id] = marker;
    google.maps.event.addDomListener(marker,'click',function()
    {
        marker.openInfoWindowHtml(marker.tekst);
    });
    return marker;
}

working fiddle

但这给了我Uncaught TypeError: marker.openInfoWindowHtml is not a function因为v3中不存在。您需要为v3更新utworzMarker函数（创建一个全局google.maps.InfoWindow对象，并使用它。）

function utworzMarker(id, lat, lng, tekst) {
    var punkt = new google.maps.LatLng(lat, lng);
    var opcje = {
        position: punkt,
        map: mapa,
        title: tekst,
        icon: ikona,
        shadow: cien
    };
    var marker = new google.maps.Marker(opcje);

    marker.tekst = tekst;
    markery[id] = marker;
    google.maps.event.addDomListener(marker, 'click', function () {
        infowindow.setContent(marker.tekst);
        infowindow.open(mapa, marker);
    });
    return marker;
}
