add event jquery code example

Example 1: jquery event listener

// There are quite a few abstracted versions of the following
$('element').on('event', function() {
	// Do something
});

// Where 'event' is something such as 'click', 'hover' etc

// They are abstracted as seen below
$('element').click(function(){
	// Do something
});
$('element').hover(function(){
	// Do something
});

// etc...

Example 2: jquery bind click

$( "#foo" ).bind( "click", function() {
  alert( "User clicked on 'foo.'" );
});
