What is the difference between scroll() and on('scroll', function() {...});?

Question

PHP

Good afternoon.
Please tell me what is the difference between $(document).scroll( function() {...} ); and $(document).on( 'scroll', function() {...} )

Answer 1

for ( ; count($json_array) = 0; $reg = $reg - 1) {

Answer 2

scroll(handler) is an alias for $(document).on( 'scroll', handler). But in the second case, you can use the $(document).on('scroll', selector, handler) syntax, which allows you to hang events on selectors, not elements (the handler will also work on those elements that are not yet on the page).
