How to use jQuery 1.4 by default on your WordPress blog

How to use jQuery 1.4 by default on your WordPress blog

As you maybe know, the new jQuery version (1.4) is out. But until the next update, your WordPress blog will still use the old jQuery version. This recipe will show you how to easily replace your current jQuery version by the newest 1.4 version.

Simply paste the following code on your functions.php file:

if( !is_admin()){
   wp_deregister_script('jquery');
   wp_register_script('jquery', ("http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"), false, '');
   wp_enqueue_script('jquery');
}

Thanks a lot to Sean Hayes for sharing this tip with me!

It’s nice, but why we need the conditional !is_admin()?

One thing worth noting is that WP’s bundled jQuery is set to jQuery.noConflict() mode. If your site relies on the Prototype library, you’re going to wind up with a clash over the $ variable using the above code.

This is a good tip, but I would advise plugin authors to take care in utilizing this method. The folks at jQuery worked to ensure backwards compatibility with scripts designed to use jQuery 1.3, but undoubtedly some scripts will fail with the changes made. As Matt Wiebe pointed out, you also have to keep in mind that jQuery in wordpress is often used in noConflict mode, and using jQuery1.4 in the above method might break scripts using mootools, prototype, etc.

My recommendation is to allow users of your plugin to toggle whether or not they want to have jQuery1.4. Perhaps stay with the wordpress-bundled jQuery and have jQuery1.4 as an optional enhancement, and make clear the benefits that 1.4 will provide to people using your plugin.
