Is it safe to call $(document).ready() from inside a function?

Question

If I use the $(document).ready() handler from within a function, will it still guarantee that the code inside it will only be run if the document is ready, even

Answer 1

Yes.

From the jQuery ready function source.

// Catch cases where $(document).ready() is called after the
// browser event has already occurred.
if ( document.readyState === "complete" ) {
    // Handle it asynchronously to allow scripts the opportunity to delay ready
    return setTimeout( jQuery.ready, 1 );
}
