JaSper v3.5 (© José M. Carnero)

Project in GitHub: github.com/jmcarnero/JaSper

JaSper is a multipurpose JavaScript library with the following features:

• DOM XPath selector and CSS selector.
• Extremely lightweight.
• Easy to extend and modularize.
• Dynamic loading (on demand) of components (normal and minified).
• Node management.
• Event management. You can add multiple events (comma separated) to one DOM element and one unique callback. Can delete all events associated to a DOM element (included anonymous callbacks), or only those associated with a specific event, ....
• Text translation.
• 'use strict'
• Event aggregator (DOM and/or custom).

Modules included:

• AJAX (JaSper_ajax.js) with start callback, end callback and fail callback.

$(document).debug().ready(function(){
	$('').eventAdd('click', function(ev){
		$('//p').toggle(500); //XPATH don't work in IE
	}).eventAdd('mousewheel', function(ev){
		if(JaSper.funcs.windowPosition().indexOf('bottom') > -1 && ev.wheelDelta == -3) alert('end of page');
	}).eventAdd('custom_event', function(ev){
