WordPress shields jQuery files loaded by themes or plug-ins

Disable loading the default jQuery library.

Function my_enqueue_scripts () {wp_deregister_script ('jquery ');} add_action ('WP _ enqueue_scripts', 'My _ enqueue_scripts ', 1 );

This code directly prohibits the introduction of jQuery plug-ins, but is also disabled in the background, which may affect the functions of the background.

Selectively load jQuery

If (! Is_admin () {// function my_init_method () {wp_deregister_script ('jquery ') is not prohibited in the background; // cancel the original jquery definition} add_action ('init ', 'My _ init_method ');} wp_deregister_script ('l10n ');

The above method first checks whether it is in the background, then removes the definition of the jQuery file, mounts it to the init filter of WordPress, and adds the above code to the functions file of the current topic.
