WordPress 3.1 not compatible with jQuery Mobile?

Question

I recently updated to WordPress 3.1, and with that update, something very interesting happened. Links became unclickable -- clicking on any link would literally result in nothing happening. Interestingly enough, all of the jQuery stuff still works. Removing the jQuery Mobile script gets rid of the problem. The error being generated was:

Error: uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIXMLHttpRequest.open]"  nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)"  location: "JS frame :: http://......./wp-includes/js/jquery/jquery.js?ver=1.4.4 :: anonymous :: line 138"  data: no]

Any idea how to fix this?

Answer 1

Just a guess, but your error message indicates that WordPress is using jQuery 1.4.4. If you look at the jQuery Mobile website, they're using 1.5. Have you tried using wp_enqueue_script to use a jQuery 1.5? You'd want to try something like:

<?php
function my_init_method() {
    if (!is_admin()) {
        wp_deregister_script( 'jquery' );
        wp_register_script( 'jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js');
        wp_enqueue_script( 'jquery' );
    }
}    

add_action('init', 'my_init_method');
?>
