Remove ajax.googleapis.com from my Wordpress site - php

Question

Any reference to googleapis will block my website in China. How can I remove these references?
Here are the results of my grep search for google api reference:
./codesearch.php:$command = "grep -ri 'ajax.googleapis.com' ./*"; ./wp-content/cache/all/privacy-policy/index.html: ./wp-content/cache/all/privacy-policy/index.html: ./wp-content/cache/all/contact/index.html: ./wp-content/cache/all/contact/index.html: ./wp-content/cache/all/index.html: ./wp-content/cache/all/index.html: ./wp-content/cache/all/author/boomerlanglearning/index.html: ./wp-content/cache/all/author/boomerlanglearning/index.html: ./wp-content/cache/all/my-account/index.html: ./wp-content/cache/all/my-account/index.html: ./wp-content/cache/all/my-account/lost-password/index.html: ./wp-content/cache/all/my-account/lost-password/index.html: ./wp-content/cache/all/terms-and-conditions/index.html: ./wp-content/cache/all/terms-and-conditions/index.html: ./wp-content/plugins/woocommerce-checkout-manager/woocommerce-checkout-manager.php: // wp_enqueue_script( 'jquery-lib', '//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js' ); ./wp-content/plugins/booster-plus-for-woocommerce/includes/settings/wcj-settings-general.php: 'default' => '//ajax.googleapis.com/ajax/libs/jqueryui/1.9.0/themes/base/jquery-ui.css', ./wp-content/plugins/booster-plus-for-woocommerce/includes/classes/class-wcj-scripts.php: $datepicker_css_path = '//ajax.googleapis.com/ajax/libs/jqueryui/1.9.0/themes/base/jquery-ui.css'; ./wp-content/plugins/woocommerce-bookings/woocommerce-bookings.php: wp_enqueue_style( 'jquery-ui-style', '//ajax.googleapis.com/ajax/libs/jqueryui/' . $jquery_version .

Here is the code I added to the functions.php file of my child theme:
function modify_jquery() {
if (!is_admin()) {
wp_deregister_script('jquery');
wp_register_script('jquery', 'https://ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.0.js', false, '1.9.0');
wp_enqueue_script('jquery');
}
}
add_action('init', 'modify_jquery');

Answer 1

wp_enqueue_scripts should do the job for the non-admin front end as you require.
add_action('wp_enqueue_scripts', 'modify_jquery', 99);
function modify_jquery(){
wp_dequeue_script( 'jquery');
wp_deregister_script( 'jquery');
wp_register_script('jquery', 'https://ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.0.js', false, '1.9.0');
wp_enqueue_script('jquery');
// repeat for your other googleapi scripts
}
Above is modified from your code - but in my case script dereg/reg and "do late" priority of 99 was unnecessary (see below).
Your grep output includes scripts which may have dependencies e.g. 'jquery' AND stylesheets. I'm not wading through through your grep; but the following is a cut and paste job example of dequeing stylesheets and handling script dependencies in child functions.php for Hemingway theme.
function dequeue_unnecessary_fonts() {
wp_dequeue_style( 'hemingway_googleFonts-css' );
wp_deregister_style( 'hemingway_googleFonts-css' );
wp_dequeue_style( 'hemingway_googleFonts' );
wp_deregister_style( 'hemingway_googleFonts' );
}
// add_action( 'wp_print_styles', 'dequeue_unnecessary_fonts',20 );
add_action( 'wp_enqueue_scripts', 'dequeue_unnecessary_fonts',20 );
// wp_print_styles (still) works for me (it can affect admin styles)
// but post WP3.3 the Codex recommends using above style functions with wp_enqueue_scripts instead
function hem_script_fix() {
wp_dequeue_script( 'hemingway_global' );
wp_enqueue_script( 'hemingway_global', get_stylesheet_directory_uri() . '/global.js', array( 'jquery' ) );
// identifies script is dependent on jquery which must be "loaded" earlier
}
add_action( 'wp_enqueue_scripts', 'hem_script_fix' );
