【问题标题】：Issue to get map to work on google maps API v3让地图在谷歌地图 API v3 上工作的问题
【发布时间】：2015-01-14 22:45:45
【问题描述】：

我无法使用 v3 脚本获取谷歌地图 (v2) 基本代码来自geozip。

你找到问题了吗？到目前为止，我认为我已经完成了 google Maps API v3 所需的所有更改，但它不起作用。而且我还不得不说我是 JavaScript 新手

工作示例 (v2)

【问题讨论】：

什么是xml.parse(doc);？
Google 地图 v2 已弃用。地图版本v=3.5exp 错误，应该是v=3.5 或v=3.exp。但是 v=3.5 已被弃用。 MarkerImage 已弃用。
好吧，现在我偶然发现了你所说的 duncan 和 geocodezip。但不幸的是它不起作用..
什么是不起作用？正如@duncan 提到的：MarkerImage 已被弃用。你改了吗？ developers.google.com/maps/documentation/javascript/…
在我的另一张地图中，MarkerImage 标签在 v3.17 中运行良好。但我现在碰巧了，但没有让它工作

【解决方案1】：

我已经修改了你的代码，现在它适合我了。

var imageGasthaus = {
    url: 'image/gasthaus.png',
    scaledSize: new google.maps.Size(26, 26),   
  };     
  var imageBar = {
    url: 'image/arzt.png',
    scaledSize: new google.maps.Size(26, 26),   
  };
      var customIcons = [];
    customIcons["restaurant"] = imageGasthaus;
    customIcons["bar"] = imageBar;
    var markerGroups = { "restaurant": [], "bar": []};

     function createMarker(point, name, address, href, tel, image, type) {
      var marker = new google.maps.Marker({
        position: latlng,
        map: map,
        icon: customIcons[type],
        zIndex: Math.round(latlng.lat()*-100000)<<5
        })

      markerGroups[type].push(marker);
      var html = "<font color='#008B00'><b>" + name + "</b></font> <br/>" + address + "<br><br>"  + href + "<br>"+ tel + "<br><br>"+ image;
      google.maps.event.addListener(marker, 'click', function() {
        infowindow.open(map, marker, html);
      });
      return marker;
    }

    function initialize() {

var myOptions = {
    zoom: 8,
    center: new google.maps.LatLng(47,15),
    mapTypeControl: true,
    mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
    navigationControl: true,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }
  map = new google.maps.Map(document.getElementById("map"),
                                myOptions);

downloadUrl("markerdata.xml", function(doc) {
        var xmlDoc = xmlParse(doc);
        var markers = xmlDoc.documentElement.getElementsByTagName("marker");

          for (var i = 0; i < markers.length; i++) {
            var name = markers[i].getAttribute("name");
            var address = markers[i].getAttribute("address");
            var tel = markers[i].getAttribute("tel");
            var href= '<a href="'+markers[i].getAttribute("href")+'" target="_blank">'+markers[i].getAttribute("web")+'</a>';
            var image = '<img src="'+markers[i].getAttribute("image")+'" width="250" height="187" alt=""/>';
            var type = markers[i].getAttribute("type");
             point = new google.maps.Lat.Lng(parseFloat(markers[i].getAttribute("lat")),
                                    parseFloat(markers[i].getAttribute("lng")));

            var marker = createMarker(point, name, address, tel, href, image, type);

          }
        });
      }



    function toggleGroup(type) {
      for (var i = 0; i < markerGroups[type].length; i++) {
        var marker = markerGroups[type][i];
        if (marker.isHidden()) {
          marker.show();
        } else {
          marker.hide();
        }
      } 
    }
