This presentation covers why libraries like jQuery exist, what was web development like before jQuery, the main benefits of jQuery, and some alternate libraries.
jQuery is a lightweight JavaScript library that simplifies HTML document traversal, event handling, animations, and Ajax interactions. It works across browsers and reduces the need for verbose JavaScript code. jQuery selects elements, handles events, performs animations and effects, and loads remote data via Ajax. It is widely used on major sites and its plug-in architecture allows developers to extend its functionality.
Last year, AOL adopted a new content strategy and has positioned itself as a premier destination for original content. Core to this strategy is having reusable, highly efficient and optimized common code and experiences at scale, which is where jQuery comes in. Check in with Dave Artz to see how jQuery has helped his front-end standards team tackle unique challenges like optimizing 3rd party widget performance, overriding plugin functionality, and managing dependencies and updates across 100+ sites spanning multiple back-end platforms.
jQuery is a JavaScript library that simplifies HTML document traversal, event handling, animating, and Ajax interactions. It allows you to write less code that does more. jQuery selects DOM elements using CSS-style selectors and provides methods for traversing, manipulating, and animating elements. Some key benefits of jQuery include writing concise code, cross-browser compatibility, and a large ecosystem of plugins.
This document provides an introduction to jQuery, including:
- A brief overview of what jQuery is and its key facts
- Details on learning jQuery through websites, tutorials, and books
- Explanations of jQuery syntax, selectors, animations, common operations, and events
- Descriptions of related tools like jQuery UI, plugins, and browser developer tools
AJAX allows web pages to load data from the server asynchronously in the background without reloading the page. It uses JavaScript to make requests to the server and update parts of the page with the response. jQuery simplifies AJAX with methods like $.get() that allow making GET requests and updating HTML. For example, an AJAX call could check username availability and update a form to display if a username is available or taken without reloading the page. Security precautions are needed when handling sensitive data with AJAX.

Javascript, DOM, browsers and frameworks basicsNet7
The DOM (Document Object Model) defines the logical structure of documents and how they can be accessed and manipulated. It was developed to promote cross-browser compatibility for JavaScript and other browser scripting languages. Early versions of JavaScript allowed basic access to HTML elements (DOM Level 0), while later versions enabled more advanced manipulation of CSS properties and document layers (Intermediate DOMs). The W3C brought together companies like Netscape and Microsoft to develop standards for ECMAScript and the DOM, with DOM Level 1 being finalized in 1998.
The document discusses Ajax technology. It defines Ajax as an asynchronous JavaScript and XML approach to exchanging data with a web server and updating parts of a web page without reloading the entire page. It describes the key technologies that enable Ajax like XMLHttpRequest, and libraries that simplify Ajax like jQuery. It also covers common uses of Ajax and issues to consider around back/forward buttons, duplicate code, and cross-domain requests.
A Rich Web Experience with jQuery, Ajax and .NETJames Johnson
The document is a presentation about providing a rich web experience using jQuery, Ajax, and .NET. It discusses JavaScript and jQuery, including jQuery syntax, selectors, chaining, traversing, manipulation, events, effects, and Ajax functionality. It also covers jQuery UI widgets and themes. The last section discusses user experience considerations like validating user input with Ajax calls.
The document summarizes key aspects of using JavaScript with the DOM:
1) The DOM represents the document as nodes that can be accessed and manipulated with JavaScript. Common methods are getElementById() and getElementsByTagName() to select nodes, and createElement() to generate new nodes.
2) Events allow JavaScript to react to user actions. Event handlers can be assigned to nodes using onclick attributes or addEventListener(). Events bubble up the DOM tree by default but can be stopped from propagating with stopPropagation().
3) The this keyword refers to the "owner" or context of the executing function, such as the HTML element to which an event handler is assigned. Understanding this is important for manipulating nodes from
The document discusses JavaScript event handling. It provides an overview of DOM Level 0 and 2-3 event models, and notes that jQuery helps normalize event handling across browsers. It describes common events like click and change, and gotchas like the 300ms delay on mobile touch events. The document recommends using event bubbling rather than attaching individual handlers, and covers properties of event objects like target, currentTarget, and timeStamp.
User Interface Development with jQuerycolinbdclark
A half-day workshop covering all aspects of user interface development with jQuery. Starts with a JavaScript refresher, followed by coverage of each major feature of jQuery. Real world code samples are included throughout.
Presented by Colin Clark and Justin Obara at the 2010 Jasig Conference in San Diego.
jQuery is a lightweight JavaScript library that simplifies HTML document traversal, event handling, animations, and Ajax interactions. It works across browsers and has a simple API that reduces code needed for common tasks. jQuery is used on over 65% of top websites and popular companies like Google use it. It allows selecting elements, modifying CSS styles and content, handling events, and developing Ajax applications through plugins.
AJAX allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes without reloading the entire page. It uses JavaScript and XMLHttpRequest objects to make HTTP requests and update portions of the web page without interrupting user operations. This provides a more interactive and responsive web experience compared to traditional page refreshes.

The document discusses different types of testing including functional and non-functional testing. It also covers topics like maintenance testing and triggers for additional testing when changes are made. Also covers concepts of Agile including DevOps, Shift Left Approach, TDD, BDD, ATDD, Retrospective and Process Improvement
The document discusses fundamentals of software testing including definitions of testing, why testing is necessary, seven testing principles, and the test process. It describes the test process as consisting of test planning, monitoring and control, analysis, design, implementation, execution, and completion. It also outlines the typical work products created during each phase of the test process.
Balancing Compaction Principles and PracticesScyllaDB
Compaction is a crucial component for preventing storage consumption from exploding. In this session, we’ll talk about why compaction is required and its principles of operation, the main compaction strategies available for use, when they should be used, and how they can be configured. Finally, we’ll present new compaction features recently introduced in ScyllaDB Enterprise and ScyllaDB Cloud.

12. the DOM? huh?!
DOM = document object model
A programming interface for HTML, XML and SVG
documents. It provides a structured representation of
the document (a tree) and it defines a way that the
structure can be accessed from programs so that they
can change the document structure, style and content.

15. // document is a global variable
var el = document.getElementById(“some id attribute”);
var elems = document.getElementsByTagName(“P”);
var myNewEl = document.createElement(“DIV”);

16. example
we’re web developers at the hot, new todo list
startup, ToDo-odles.
let’s write the html for viewing a todo list.
18. // Find the New button
var addNewBtn = document.getElementById(“new-btn”);
// Listen to click events on the New button
addNewBtn.addEventListener(“click”, function () {
alert(“Clicked the New button”);
// do something else
});
let’s make this interactive
20. x-browser issues
Until IE 9, IE didn’t implement addEventListener; it
had its own – attachEvent
Solution:
function onClickHandler() {
alert(“Clicked the New button”);
}
var addNewBtn = document.getElementById(“new-btn”);
if (IE < 9 /* Pseudo-code for < IE 9 check */) {
addNewBtn.attachEvent(“click”, onClickHandler);
} else {
addNewBtn.addEventListener(“click”, onClickHandler);
}
21. other x-browser issues across vendors
• varying support for HTML5 features
• missing api methods like,
• distinct rendering and positioning content
• two different ways to make ajax calls
Array.prototype.forEach
23. about jQuery
• makes web development easier
• written by John Resig in 2006
• 65.5% of Quantcast Top 10k sites

25. why use jQuery?
• a common interface to manipulate the DOM
– the jQuery object
• css selectors for DOM queries
• plugin system

26. $ ftw!
// Find all paragraph elements
var $pTags = $(“p”);
// Find all elements with class attribute “titles”
var $titles = $(“.titles”);
// Find element with id attribute “my-div”
var $myDiv = $(“#my-div”);
if ($ === jQuery) {
alert(“$ and jQuery are global and equal”);
}
29. interactivity with jQuery
// Change the color of the title
$(“#title”).css(“font-size”, “36pt”);
// Listen to click events on the New button
$(“#new-btn”).on(“click”, function() {
alert(“Clicked the New button”);
$(this).addClass(“inactive”);
}
notice there’s no need to check IE version; jQuery
does it internally!
30. more examples
// Append a new item to the list
var html = ‘<li class=“item”><span class=“item-title”>’ +
‘Get Milk</span><span class=“item-desc”>1% milkfat</span></li>’;
$(‘#task-list’).append(html);
// Remove last item in the list from the DOM
$(“#task-list”).find(“.item:last-child”).remove();
// Add class, “urgent” to the first element with class “item”
$(“.item”).eq(0).addClass(“urgent”);
32. what is ajax?
ajax = asynchronous javascript and xml
With Ajax, web applications can send data to and
retrieve from a server asynchronously (in the
background) without interfering with the display and
behavior of the existing page.
learn more: https://en.wikipedia.org/wiki/Ajax_(programming)
33. why ajax?
• dynamic web pages – partial updates to page
sections without needing to reload the page
• responsive web experiences – saving and fetching
information appears to happen instantly
34. how?
var xhReq;
// Less than IE 7 support
if (window.ActiveXObject) {
xhReq = new ActiveXObject(“Msxml2.XMLHTTP”);
} else {
xhReq = new XmlHttpRequest();
}
// Make an async request
xhReq.open(“GET”, “my-app-endpoint?id=2”);
xhReq.onreadystatechange = function() {
// We only care about complete requests (state = 4)
if (xhReq.readyState != 4) { return; }
if (xhReq.status != 200) {
// Handle error
} else {
// Handle success via xhReq.responseText
}
};
xhReq.send(null);
36. ajax with jQuery
learn more: full jQuery documentation – http://api.jquery.com/
// No need to deal with XMLHttpRequest to do AJAX
// jQuery does AJAX!
$.ajax({
url: “/my-app-endpoint”,
type: “GET”,
data: { id: 2 },
success: function (response) {
// Handle the response
},
error: function () {
// Handle the error
}
});
37. best practices
// Prefix all variables that reference a jQuery object with
a “$”
var $taskList = $(“#task-list”);
// A jQuery object is array-like; check the length to see
if an element exist
var $someElement = $(“#parent .non-existing-selector”);
console.log($taskList.length); // 1
console.log($someElement.length); // 0
38. more best practices
// jQuery objects are chain-able
$(“#title”)
.addClass(“crucial”)
.text(“Pay Attention”)
.on(“click”, function () { /* Do something*/ });
// Use event delegation to bind events to multiple instances of
the same html markup
$(“#task-list”).on(“click”, “.item”, function () {
// Do something when a .item element is clicked
});
always prefer css over javascript; css is much faster
41. prototype.js
learn more: http://prototypejs.org/
• really stable – 1.7 release since Nov 2010
• extends native DOM – adds methods to
Element
• id DOM search like
• css DOM search like
Element
$(“id-attribute”)
$$(“p.title”)
44. single page apps
Single-Page Applications (SPAs) are Web apps that
load a single HTML page and dynamically update
that page as the user interacts with the app.
SPAs use AJAX and HTML5 to create fluid and
responsive Web apps, without constant page
reloads. However, this means much of the work
happens on the client side, in JavaScript.

45. component-based development
Component-based development is a software
design pattern where view logic (how
interactions are controlled) are fully
encapsulated in a component or widget.
The strategy leads to better maintainability
and greater code re-use.
47. jQuery is completely optional
with the exception of Flight (which uses
jQuery), the SPA frameworks don’t require you
to use any additional libraries.
on the component level, you always have
access to the DOM nodes so, you rarely need
to traverse the DOM tree from the root node.
50. jQuery summary
• provides x-browser functionality for DOM manipulation and ajax
• makes web development easier
• always, prefer css solutions over javascript with jQuery
• exposes a common interface that make plugins possible. See:
