我有谷歌地图..标记从xml获取数据..一切正常..但我想写信息从xml到标签..但我不知道怎么做..请看我的代码..帮助我：（（

          var gmarkers = [];

这是xml

      downloadUrl("xml/cat.xml", function(doc) {

  var xml = xmlParse(doc);

  var markers = xml.documentElement.getElementsByTagName("marker");

        for (var i = 0; i < markers.length; i++) {
          // obtain the attribues of each marker
          var lat = parseFloat(markers[i].getAttribute("lat"));
          var lng = parseFloat(markers[i].getAttribute("lng"));
          var point = new google.maps.LatLng(lat,lng);
         var address = markers[i].getAttribute("address");
          var id = markers[i].getAttribute("id");
          var name = markers[i].getAttribute("name");
          var html = contentString;
          var category = markers[i].getAttribute("category");
          // create the marker
          var marker = createMarker(point,name,html,category);
        }


        // == show or hide the categories initially ==
        show("intake");
        hide("reservoir");

        show("wtp");
        hide("wwps");
        hide("wwtp");
        // == create the initial sidebar ==

      });


 toggleKML = function(x) {

如何将xml数据放入contentstring？

我的xml示例也是..

<marker code="20070" id="WWS7" name="8 Wells Nisaqala Gallery" title="NWSSP-2" capacity="9.84" completed="0" lat="xxx" lng="xx"  category="intake"/>

Answer 1

您需要根据标记上的click事件设置infowindow的内容。您最需要使用闭包来完成此操作。现在你每次都设置相同的内容，因为contentString永远不会改变。您只需要使用XML文件中的值在Click事件处理程序中设置该内容。

Answer 2

我已经意识到你要求的东西，你可以在这里查看我的代码：http://turom-mice.it/condorincentive/incentive.html（使用Firebug来获取脚本和相关的XML文件）代码尽可能地被评论，但如果您需要解释，请询问。代码是此处各种搜索和阅读以及Google Maps v3 API /示例的结果。

希望它有所帮助。皮疹*
