wordpress - Everyone is installing jQuery library on my site -

i using wordpress, comes built-in jquery library. when install plugin, version gets way in. larn write own code, tutorial asks me install one!

at time of writing, have 4-5 versions of jquery library installed!

it's going crazy! , don't think need many, need latest 1 google cdn best performance, set line in php file, didn't seem show anywhere after cleared cache.

function mytheme_jquery_enqueue(){ if(!is_admin()){ wp_deregister_script('jquery'); wp_register_script('jquery', "http" . ($_server['server_port'] == 443 ? "s" : "") . "://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js", false, null); wp_enqueue_script('jquery'); } } add_action('wp_enqueue_scripts', 'mytheme_jquery_enqueue');

how prepare , rid of every other unnecessary version?

first, seek give hook lower priority, e.g.:

add_action( 'wp_enqueue_scripts', 'mytheme_jquery_enqueue', 99999 );

this way, it'll latest run, unless plugin has priority of 9999999... it's horse race...

then, enqueuing jquery in plug-ins

if code (or theme's code) unregistering jquery , re-registering location (google), need add together somewhere:

jquery.noconflict();

this makes jquery cooperate other scripts (i.e. prototype) seek define $ variable globally. wordpress has line bundled version, google not.

but, improve enqueuing cdn yourself, it's recommended utilize plugin: use google libraries. according core developer:

please not utilize method include jquery script google. above doesn't work , cause conflicts other scripts, along other issues. utilize "use google libraries" plugin instead, if want utilize google hosted versions of libraries. plugin right, , updated often. method above work superficially, cause problems downwards line. – otto jul 29 '12 @ 15:57

then, have issue not recommended load other jquery libraries , utilize 1 bundled wordpress. in case, should utilize remove_action, wp_deregister_script or wp_dequeue_script prevent plugins or theme load versions.
