jquery won't load in footer

Question

I wanted to move jquery to the site's footer, but that doesn't work. I've tried it with the following code.

As you can see, I have a couple of another scripts and they load correctly on the footer. Only jquery won't work.

//This adds our JavaScript Files
function wel_adding_scripts() {

wp_deregister_script('jquery');
wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js', '', '2.1.1', true); 
wp_enqueue_script( 'jquery');

wp_register_script('jquery.mixitup', get_template_directory_uri() . 'js/jquery.mixitup.min.js','','1.1', true);
wp_enqueue_script('jquery.mixitup');

wp_register_script('headroom', get_template_directory_uri() . 'js/headroom.min.js','','1.1', true);
wp_enqueue_script('headroom');
}
add_action( 'wp_enqueue_scripts', 'wel_adding_scripts' ); 

Answer 1

Note that if any script in the header at all needs jQuery then it will bump it to header, regardless if it's changed to be enqueued for footer.

So while changing it to be queued for footer makes sense it rarely works out when a lot of script stuff is going on.

Answer 2

Here is the problem

If you try to register or enqueue an already registered handle with different parameters, the new parameters will be ignored. Instead, use wp_deregister_script() and register the script again with the new parameters.

You will have to deregister jquery first, the register it again, but becareful because the empty string isn't what you should put in the place of the deps parameter. IT should be an empty array.

Like this:

     wp_register_script('jquery',
 'http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js',
     array() , '2.1.1', true); 

Answer 3

Fixed: I have do it the right way, all the time. Now i found, that jquery was deregistered at the themes header.php file. I have deleted it and it works now.

Answer 4

<?php
function your_function() {
    echo '<p>This is inserted at the bottom</p>';
}
add_action('wp_footer', 'my_function');
?>

You can use this hook. This is used to load the script in the footer try it let me know for any doubts.
