将自定义html添加到KML数据的信息窗口 [英] Adding custom html to infowindow of KML data

问题描述

我希望Google地图(geoxml3)专家可以为您提供帮助.我想做的事情实际上非常简单，但是我只是不够熟练地编写代码来完成它.

I am hoping a Google maps (geoxml3) expert may be able to help. What I am trying to do is really quite simple, but i'm just not savvy enough with coding to accomplish it.

我有一个使用google maps api v3和geoxml3的简单地图，其中加载了一些KML数据.

I have a simple map using the google maps api v3 and geoxml3 which loads some KML data.

然后，我有一个自定义生成的侧边栏，它与每个地标相对应.

I then have a custom generated sidebar which corresponds to each placemark.

我只想像下面的示例一样在信息窗口中添加放大和缩小按钮.

I would simply like to add zoom in and zoom out buttons to the infowindow like in the following example.

我知道我必须创建一个自定义标记并添加html内容，但是要使其与kml单击配合使用，我遇到了很多麻烦.

I know that I have to create a custom marker and add the html content, but I am having a lot of trouble getting it to work with the kml click.

我还没有尝试过使用自定义标记btw ...

I have not included an attempt at the custom marker btw...

此处示例:

到目前为止，我的代码:

My code so far:

var geoXml = null;
var map = null;
var myLatLng = null;
var infowindow = null;
var filename = "KML_Samples.kml";
var image = ""; 

function initialize() {
myLatLng = new google.maps.LatLng(-28.014408,153.463898);

var myOptions = {
    zoom: 11,
    center: myLatLng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
};

map = new google.maps.Map(document.getElementById("googlemap"),myOptions);
infowindow = new google.maps.InfoWindow({maxWidth:300});

geoXml = new geoXML3.parser({
    map: map,
    infowindow: infowindow,
    singleInfoWindow: true,
    markerOptions: {icon: image},
    afterParse: useTheData
});
geoXml.parse(filename);
};                  
function kmlClick(marker) {
    google.maps.event.trigger(geoXml.docs[0].markers[marker],"click");
}
function useTheData(doc){
// Geodata handling goes here, using JSON properties of the doc object
for (var i = 0; i < doc[0].markers.length; i++){}
};
google.maps.event.addDomListener(window, 'load', initialize);

花了我相当长的时间才使它起作用，所以如果这真的很简单，请原谅我.

It took me quite a while just to get this to work, so please forgive me if this is really simple stuff.

任何帮助将不胜感激.

推荐答案

向geoXML3.parser()

使用内置函数创建的标记并且仅修改infoWindow的内容的简单方法:

A simple approach that uses the marker created by the built-in function and only modifies the content for the infoWindow:

infowindow = new google.maps.InfoWindow({minWidth:250, maxWidth:300});
geoXml = new geoXML3.parser({
    map: map, 
    infowindow: infowindow,
    singleInfoWindow: 1,
    afterParse: useTheData,

    createMarker: function (placemark, doc) {
      //get the marker from the built-in createMarker-function
      var marker=geoXML3.instances[0].createMarker(placemark, doc);
      //modify the content
      if(marker.infoWindow){
        marker.infoWindowOptions.content=
        '<div class="geoxml3_infowindow"><h3>' + placemark.name +
        '</h3><div>' + placemark.description + '</div>'+
        '<code onclick="map.setCenter(new google.maps.LatLng'+
          marker.getPosition().toString()+
        ');map.setZoom(map.getZoom()+1);">zoom in</code><br/>'+
        '<code onclick="map.setCenter(new google.maps.LatLng'+
          marker.getPosition().toString()+
        ');map.setZoom(map.getZoom()-1);">zoom out</code>'+
        '</div>';
      }
    return marker;
  }
});
