Loading a newer version of jQuery within WordPress

Question

I've read about the WP enqueue_script() function, but if I wanted to use a newer version of jQuery than what my WP installation is using, can I load it through this & WP will use the latest version? or will it load both? or what will happen?

Thanks!

Answer 1

To replace the default jQuery url, do:

wp_deregister_script( 'jquery' );
wp_register_script( 'jquery', 'your custom url', ... );

Then call wp_enqueue_script( 'jquery' ); as usual.

Note that various pages in the WP admin might not be compatible with never versions of jQuery, not to mention plugin scripts.

Answer 2

You can (de)register the builtin jquery with the following functions:

wp_deregister_script('jquery');

And register a new jquery library:

wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js', array(), '1.4', true);
