How to check if jQuery UI widget is loaded?

Question

I know I can check if jQuery UI core is loaded with jQuery.ui, but how to check if a widget (draggable) is loaded, I am using typeof($('something').draggable) == 'function', is any better way to do this?

Answer 1

You can try like this:

if (typeof(jQuery.ui.draggable) != 'undefined'){
    // UI draggable is loaded
}
