I have a geojson file (tide\_gauges.geojson)

```
{
"type": "FeatureCollection",
"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" } },                                                                                
"features": [
{ "type": "Feature", "properties": { "NUMERO": "10569", "MAREGRAFO": "COCALZINHO", "FICHA": null }, "geometry": { "type": "Point", "coordinates": [ -4, -1 ] } },
{ "type": "Feature", "properties": { "NUMERO": "50240", "MAREGRAFO": "PONTA DE PARANAPUA", "FICHA": null }, "geometry": { "type": "Point", "coordinates": [ -4, -2 ] } }...

```

I retrieved this Json file in a variable:

```
var estacoes = new L.geoJson();
estacoes.addTo(map);

$.ajax({
dataType: "json",
url: "geojson/tide_gauges.geojson",
success: function(data) {
    $(data.features).each(function(key, data) {
        estacoes.addData(data);
    });
}
}).error(function() {});

```

I am in need to set all the feature properties (`NUMERO`,`MAREGRAFO`,`FICHA`,`LATITUDE` and `LONGITUDE`) in a popup that appears after a click over point feature on the map.

I tried the code below, but it is not enough:

```
var popupContent ="";
for (var k in feature.properties) {
    var v = String(feature.properties[k]);
    popupContent += k + '->' + v ;

```

Could someone give some tips on that, please?
