Benchmark: jQuery event On Performance

HTML Preparation code:

<script src="//ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>

<style>
  #container { visibility: hidden; }
</style>

<div id="container">
</div>

Script Preparation code:

var container = $('#container')
var itemCount = 300;

for (var i = 0; i < itemCount; i++) {
  container.append('<div>Item ' + i + '</div>');
}

var items = container.children();

Tests:

.each loop and multiple on-assignenements
items.each(function(index,item) { var $item = $(item); $item.on('click', function() { console.log('Item clicked'); }); $item.on('hover', function() { console.log('Item hovered'); }); $item.on('mouseenter', function() { console.log('Item mouseentered'); }); }); items.each(function(index,item) { var $item = $(item); $item.off('click'); $item.off('hover'); $item.off('mouseenter'); });
.each loop and single on-assignement
items.each(function(index,item) { var $item = $(item); $item.on('click', function() { console.log('Item clicked'); }); }); items.each(function(index,item) { var $item = $(item); $item.off('click'); });
no loop and .on-assignement on list
items.on('click', function() { console.log('Item clicked'); }); items.off('click');
