How to Use jQuery's $.ajax() Function. Without any doubt Ajax has taken web development by storm and it’s one of the most successful paradigms ever.
In my article An Introduction to jQuery’s Shorthand Ajax Methods, I discussed some of jQuery’s most used Ajax shorthand methods: $.get(), $.post(), and $.load(). They are convenient methods for making Ajax requests in a few lines of code. Sometimes, we need more control over the Ajax calls we want to make. For example, we want to specify what should happen in case an Ajax call fails or we need to perform an Ajax request but its result is only needed if retrieved within a certain amount of time. In such situations, we can rely on another function provided by jQuery, called $.ajax(), that is the topic of this tutorial. The $.ajax() Function The jQuery’s $.ajax() function is used to perform an asynchronous HTTP request. . $.ajax(url[, options]) $.ajax([options]) In its first form, this function performs an Ajax request using the url parameter and the options specified in options.
Ajax. Asynchronous JavaScript + XML, while not a technology in itself, is a term coined in 2005 by Jesse James Garrett, that describes a "new" approach to using a number of existing technologies together, including: HTML or XHTML, Cascading Style Sheets, JavaScript, The Document Object Model, XML, XSLT, and most importantly the XMLHttpRequest object. When these technologies are combined in the Ajax model, web applications are able to make quick, incremental updates to the user interface without reloading the entire browser page. This makes the application faster and more responsive to user actions. Although X in Ajax stands for XML, JSON is used more than XML nowadays because of its many advantages such as being lighter and a part of JavaScript. Both JSON and XML are used for packaging information in Ajax model. Documentation Getting Started This article guides you through the Ajax basics and gives you two simple hands-on examples to get you started.
Using the XMLHttpRequest API Fetch API XPath. jQuery.ajax() Description: Perform an asynchronous HTTP (Ajax) request. The $.ajax() function underlies all Ajax requests sent by jQuery. It is often unnecessary to directly call this function, as several higher-level alternatives like $.get() and .load() are available and are easier to use. If less common options are required, though, $.ajax() can be used more flexibly. At its simplest, the $.ajax() function can be called with no arguments: Note: Default settings can be set globally by using the $.ajaxSetup() function. This example, using no options, loads the contents of the current page, but does nothing with the result. The jqXHR Object The jQuery XMLHttpRequest (jqXHR) object returned by $.ajax() as of jQuery 1.5 is a superset of the browser's native XMLHttpRequest object.
As of jQuery 1.5.1, the jqXHR object also contains the overrideMimeType() method (it was available in jQuery 1.4.x, as well, but was temporarily removed in jQuery 1.5). Callback Function Queues Data Types Sending Data to the Server. Alternate Ajax Techniques, Part 1. By Nicholas C. Zakas. By now, nearly everyone who works in web development has heard of the term Ajax, which is simply a term to describe client-server communication achieved without reloading the current page.
Most articles on Ajax have focused on using XMLHttp as the means to achieving such communication, but Ajax techniques aren't limited to just XMLHttp. There are several other methods; we'll explore some of the more common ones in this series of articles. Dynamic Script Loading The first alternate Ajax technique is dynamic script loading.
The Technique The basic technique behind dynamic script loading is easy, all you need to do is create a <script/> element using the DOM createElement() method and add it to the page: var oScript = document.createElement("script"); oScript.src = "/path/to/my.js"; document.body.appendChild(oScript); Downloading doesn't begin until the new <script/> element is actually added to the page, so it's important not to forget this step.
