Details

The method returns a promise that:

is resolved when the data are loaded

$$("grida").loadNext(10,0,null,"data/data.php").then(function(data){
    var json = data.json();
});

is rejected if a loading error occurs or if you attempt to request the same portion of data

$$("grida").loadNext(10,0,null,"data/data.php").fail(function(){
    // your code here
});
// catch is the Webix alias if fail()
$$("grida").loadNext(10,0,null,"data/data.php").catch(function(){
    // your code here
});
