javascript - Why won't featureClick work in my cartoDB map? -

-

i can except featurecclick work.

my js:

window.onload = function(){     var cartodbtablename = 'sipri_import_export_map_1950_2014';     var domid = 'map';     var mapstyle = document.getelementsbyclassname('map-style');     var lat = 0;     var lon = 0;     var zoomlvl = 2;     var options = {         center: [lat,lon],         zoom: zoomlvl     };     var mapobject = new l.map(domid,options);     var layersource = {         user_name: 'chrismp',         type: 'cartodb',         sublayers: [             {                 sql: "select * "+cartodbtablename+" (gwsyear <= 1950 , gwsyear > 0)",                 cartocss: mapstyle[0].innerhtml             }         ]     };      l.tilelayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png')         .addto(mapobject);      cartodb.createlayer(mapobject,layersource)         .addto(mapobject)         .on('done',function(layer){                 layer.getsublayer(0).on('featureclick', function(e, latlng, pos, data, sublayerindex) {                   console.log(e, latlng, pos, data, sublayerinde);                 }).on('error',function(err){                     console.log('featureclick error: '+err);                 });         }).on('error',function(err){             console.log(err);         }); };

my map loads styling, cursor doesn't switch finger-pointer when it's on country, nothing happens when click it. gives?

i had similar problem - feel cartodb's documentation on little patchy... believe need add this:

 cdb.vis.vis.addinfowindow(map, sublayers, [/*add desired info fields here*/]);

so example:

 cartodb.createlayer(mapobject,layersource)     .addto(mapobject)     .on('done',function(layer){              //add these 2 lines here             sublayers = layer.getsublayer(0);             cdb.vis.vis.addinfowindow(map, sublayers, [/*add desired info fields here*/]);               layer.getsublayer(0).on('featureclick', function(e, latlng, pos, data, sublayerindex) {               console.log(e, latlng, pos, data, sublayerinde);             }).on('error',function(err){                 console.log('featureclick error: '+err);             });     })

hope helps.
