I’m sure you read Scirra’s Making A Fast Website (if not, you should probably stop reading this and head over there now…seriously, why are you still reading this?), which explains that the best place to put your
<script> tags is in the footer, just before
</body>. However, if you try to register a WordPress default script, such as jQuery, in the footer, the script will still be rendered to the
<head> section during
That’s no good — you want to load jQuery during
wp_footer(). No worries, there’s a quick fix for that.
WordPress pre-registers default scripts to make your life easier. To load jQuery, this is all you need:
wp_enqueue_script( 'jquery' );
However, with the convenience comes a consequence: because jquery is already registered using
wp_register_script(), we don’t have the option to change that script’s
$in_footer parameter to
Thankfully, there is a quick fix:
wp_deregister_script( 'jquery' ); //deregister and re-enqueue to load in footer wp_enqueue_script( 'jquery', '/wp-includes/js/jquery/jquery.js', false, '1.8.3', true );
And just like that, your site is fully optimized for maximum speed. Ok, maybe not fully optimized, but you’re off to a good start.
