Russian CDN for jQuery

I recently discovered that the biggest Russian search engine Yandex (yeah, it’s bigger than Google in Russia) is using jQuery on its home page. It also hosts all previous jQuery versions on it’s fast gzip enabled servers just like Google and MIcrosoft do.

Because most of the Russian internet users have visited Yandex already, they already have it in their browser cache. I also did route tracing from Russian server to Google CDN servers and I was directed to the server in California, USA and pining the local Russian CDN server was at least 3 times faster.

Anyway, if you decide to use Russian CDN to host your jQuery files here are the links:

Minified versions

Non minified versions

jQuery UI links

Hosted versions
1.8.2, 1.8.1, 1.8.0, 1.7.3, 1.7.2, 1.7.1, 1.7.0, 1.6.0

jQuery UI modules can be downloaded seperately

Language files

jQuery UI CSS files (matches original directory names)

iPhone / iPod detection using jQuery & JavaScript

In this post you will learn how to detect iPhone/iPod using javascript/jQuery, redirect your iPhone users to mobile version of your site using javascript and alternative and better way to redirect your visitors using server-side PHP code snippet.

The latest buzz around jQuery is upcoming jQuery mobile – support for mobile devices. Current jQuery core work fine on iPhone and iPod touch browsers and most of us have created a mobile version of our websites, developed or converted websites for others. Basically, jQuery is already being used on iPhone and iPod touch devices. Without any further ado…

Javascript code to detect iPhone and iPod browsers

// Return boolean TRUE/FALSE
function isiPhone(){
    return (
        (navigator.platform.indexOf("iPhone") != -1) ||
        (navigator.platform.indexOf("iPod") != -1)

You might wonder why do we even need to detect if our website is ran on iPhone Safari or normal desktop Safar if jQuery works fine on both. Well, there are Safari specific CSS features that you might want to utilize and you need to know if the current browser is Safari, then you may also want to consider reducing resource consuming features like animations for iPhone version of your site.

Redirecting iPhone & iPod users

You may also use this script to redirect iPhone and iPod users to your website’s mobile version:

// Redirect iPhone/iPod visitors
function isiPhone(){
    return (
        (navigator.platform.indexOf("iPhone") != -1) ||
        (navigator.platform.indexOf("iPod") != -1)
    window.location = "";

For example: if your website is and you have a mobile version at, then put the following script to your

Redirect iPhone users using PHP

It is better to detect and redirect your iPhone users on the server-side. Here is a PHP code to redirect iPhone users:

// Redirect iPhone/iPod visitors
if(strpos($_SERVER['HTTP_USER_AGENT'], 'iPhone') ||
   strpos($_SERVER['HTTP_USER_AGENT'], 'iPod')){

User agent strings for your reference:

User Agent String for iPhone
    Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko)
    Version/3.0 Mobile/1A543a Safari/419.3
User Agent String for iPod Touch
    Mozilla/5.0 (iPod; U; CPU like Mac OS X; en) AppleWebKit/420.1 (KHTML, like Gecko)
    Version/3.0 Mobile/3A101a Safari/419.3

As final words, I would like to remind you that sometimes your visitors would not like to be redirected to mobile versions of your websites. That’s why your mobile version should always include a link to your non-mobile website. The above scripts can be rewrote to check if user has chosen not to be redirected. Either set cookie or a URL parameter.

jQuery mobile source code

If you want to download jQuery Mobile source code and look into it just like everybody else, we are all out of luck :(  As I mentioned in my previous post jQuery mobile facts, the source code will be available in October this year.

The jQuery Mobile source will not be in a separate file. It will be right in the jQuery core. This means that jQuery team is fixing and improving jQuery core so that it works nicely in all major mobile phones and devices.

By the way, if you want to keep track of the jQuery mobile source code and be the first one to download it, when it is available, you should watch jQuery on GitHub.

The big part of the upcoming jQuery mobile is new UI components that work and render nicely in all mobile devices and degrade gracefully. So, keep an eye on jQuery UI as well. Here is the jQuery UI GitHub page.

Meanwhile you can read all jQuery mobile facts here.

jQuery & Cookies (get/set/delete & a plugin)

In this post I would like to share javascript functions that will help you easily get, set, delete and basically manage your cookies. Also, link to jQuery Cookie plugin, it’s improved version with more functions and of course easy to read and short examples on how to use these functions.

I will try to keep this post short and will not explain what cookies are and how to eat them. There are plenty of articles covering it already.

Here are javascript functions by Peter-Paul Koch to getCookie(), setCookie() and deleteCookie():

function setCookie(name,value,days) {
    if (days) {
        var date = new Date();
        var expires = "; expires="+date.toGMTString();
    else var expires = "";
    document.cookie = name+"="+value+expires+"; path=/";

function getCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    return null;

function deleteCookie(name) {
  Changed function names from readCookie(), createCookie()
  and eraseCookie() to getCookie(), setCookie() and

Here is an example that shows you how to use those functions in your javascript to create, edit and delete your cookies:

// Create/write a cookie and store it for 1 day
setCookie('myCookie', 'myValue', 1);

// Get my cookie

// Delete/erase my cookie

These 3 javascript functions are all you need to manage your cookies, but if you want to do it in “jQuery style” than you can use jQuery Cookie plugin or it’s improved version.

Here is how to use jQuery Cookie plugin in your code:

// Setting a cookie

// Creating cookie with all availabl options
$.cookie('myCookie2', 'myValue2', { expires: 7, path: '/', domain: '', secure: true });

// Get a cookie

// Delete a cookie
$.cookie('myCookie', null);
With an improved version of the plugin you can set and get multiple cookies in one call. The improved version of the jQuery Cookie pluin only adds few additional bytes. So it really worth it. 
// Set multiple cookies
$.cookie({ 'cookie1':'value1', 'cookie2':'value2' });
