Callbacks

Since webix.confirm() returns a promise, there is no need in a callback functions. However, you can add a callback if this is necessary. As a parameter, the function receives the confirm result status (true or false).

// basic initialization 
webix.confirm("Test confirm", "confirm-warning", function(result){
    webix.message(result);
});
 
// extended initialization
webix.confirm({
    title: "Close",
    text: "You can't close this window!",
    type:"confirm-error",
    callback:function(result){
        webix.message(result);
    }
});
