There is no Ajax object in browser, but there is XMLHTTPRequest. But again - you must learn how to use it first.

Instead, we're going to be focused on those who are just getting started with jQuery.Perhaps you've gone through several JavaScript tutorials, built several small sites or projects that incorporate JavaScript into the page (or the site) to some degree, and now you're ready to get started with a new framework or library.If you're reading this tutorial, then I assume you're interested i
defined. This can be a pretty serious problem if your web app relies on jQuery (57.7% of all sites!), since if jQuery fails to load, it can make your JavaScript code unusable. What are the common causes? The most obvious cause of this error are that you forgot to include jQuery before you used it, but there are also more subtle causes that you’ll not see until you deploy your site to production: 1. Your CDN-hosted jQuery might be blocked If you are using a CDN-hosted version of jQuery such as Google’s Hosted Libraries, these CDNs might be blocked by a filter or proxy service on your customers’ connection. We typically see this issue with requests originating from Chinese or Indonesian IP addresses. 2. Your CDN-hosted jQuery is down or timing out Another common example of this bug is when the CDN hosting your jQuery script unreliable or slow to load. Browsers typically have a timeout of around 20-30 seconds for each script tag. How can I fix this? Luckily there is a simple solution to most of these issues. You can easily provide a locally-hosted fallback version of jQuery as follows: // First try loading jQuery from Google's CDN // Fall back to a local copy of jQuery if the CDN fails script window.jQuery || document.write(' If you have a rails app, you can alternatively use the jquery-rails gem, which automates this fallback process for you. This technique is used on many popular sites, including jquery.com, and solves most jQuery is not defined errors. If the CDN jQuery fails load, it will almost certainly load fine from your own domain, but you’ll also see the benefits of using a CDN-hosted jQuery for most of your users. Is this is a problem on my site? It is practically impossible to protect against every JavaScript issue when developing you
