[OpenLayers-Users] Export Vector Layer as KML or GPX

[cromail]

Hello everybody,

 

im using OpenLayers 2.12 and want to export vector layers (some routes served by geoserver) as kml and gpx files.

Now i found two different api versions:

http://dev.openlayers.org/docs/files/OpenLayers/Format/KML-js.html

which has a lot more functions then

http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers/Format/KML-js.html

which has only the write function to export.

 

I wonder which one works, or with which OL version.

Using the first one get the following errors (complete code below):

Uncaught TypeError: Cannot read property 'collection' of undefined

when i try

console.log(format.buildGeometry.multilinestring(record.data.geometry));

or

Uncaught TypeError: Object #<Object> has no method 'createElementNS'

when i try to export a single linestring

console.log(format.buildGeometry.linestring(record.data.geometry.components[0]));

 

Is there something i'm missing or doing wrong? Below is my code snippet.

 

I think the MultiLineString Object should be ok, as it looks like this

constructor {raw: Object, modified: Object, data: Object, hasListeners: HasListeners, events: Object…}

1. data: Object
   1. geometry: C
      1. bounds: OpenLayers.Bounds.OpenLayers.Class.initialize
      2. components: Array[334]
         1. [0 … 99]
         2. [100 … 199]
         3. [200 … 299]
         4. [300 … 333]
         5. length: 334
         6. __proto__: Array[0]
      3. id: "OpenLayers.Geometry.MultiLineString_2691"

 

This is my code snippet:

onDownloadRouteClick: function(grid, view, rowIndex, colIndex){
        var record = grid.getStore().getAt(rowIndex);               // the MultilineString Object seen above
            var format = new OpenLayers.Format.KML({
                internalProjection: this.getMappanel().map.baseLayer.projection,
                externalProjection: new OpenLayers.Projection("EPSG:4326")
            });
        console.log(format.buildGeometry.multilinestring(record.data.geometry));

 

 

Finally (after solving this problem ;) i'm facing the next problem how to get the user friendly download popup. If somebody as experience/ or an example how i can get a downloadable file from the string i would be very thankful :)

 

Thanks

Christian
