jQuery -> bind / live / delegate 终结者 – on

<div class="container">
	<div class="box">hello world</div>
</div>

$(document).ready(function() {
	$('.box').live('click', function() {
		$(this).clone().appendTo('.container');
	});
});

$( "#dataTable tbody tr" ).on( "click", function() {
  alert( $( this ).text() );
});

$( "#dataTable tbody" ).on( "click", "tr", function() {
  alert( $( this ).text() );
});

function greet( event ) {
  alert( "Hello " + event.data.name );
}
$( "button" ).on( "click", {
  name: "Karl"
}, greet );
$( "button" ).on( "click", {
  name: "Addy"
}, greet );
