Export GPX file from Leaflet - export

Question

What I want to do is let the users create a GPX file by selecting some GeoJson features in Leaflet. The way in which I'm doing it is by creating a new GeoJson layer to store the selected features, then converting this to gpx with a plugin called togpx (https://github.com/tyrasd/togpx). Now I have a gpx file, but I don't know how can I let the users download it. Any suggestions? Here's my code:
var GPXfile;
var trails = new L.GeoJSON.AJAX('data/trasee.geojson', {
onEachFeature: function(feature, layer) {
layer.on({
click: function () {
var selectedGeojson = {
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"properties": {
"name": "Rocka Rolla"
},
"geometry": {
"type": "LineString",
"coordinates": feature.geometry.coordinates
}
}]
}
GPXfile = togpx(selectedGeojson);
}
})
}
}).addTo(map);

Answer 1

You can try that ...
A link to trigger the dowload:
Export to file
Some javascript (you have to include jquery):
$("#exportGPX").on('click', function (event) {
// prepare the string that is going to go into the href attribute
// data:mimetype;encoding,string
data = 'data:application/javascript;charset=utf-8,' + encodeURIComponent(gpxData);
// set attributes href and target in the <a> element (with id exportGPX)
$(this).attr({
'href': data,
'target': '_blank'
});
// let the click go through
});

Note: it works with Chrome, but you should try other browsers too.
