Enqueue jquery in wordpress?

Question

Im having some trouble adding jquery libraries to a custom wordpress plugin. It's telling me it cant find variable jQuery. Any help is much appreciated.

simplepluginclass.php includes functions.php

include plugin_dir_path( __FILE__ ) . 'inc/functions.php';

functions.php

 <?php
        function register_jqscripts() {
            wp_enqueue_script('jQuery', 'http://code.google.com/apis/libraries/devguide.html#jquery');
            wp_enqueue_script('jquery-ui-core', 'https://code.jquery.com/ui/1.12.1/jquery-ui.min.js');
            wp_enqueue_script('jquery-ui-datepicker');
            wp_enqueue_style('jquery-ui-css', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.2/themes/smoothness/jquery-ui.css');
        }


    function add_datepicker(){ ?>
    <script type="text/javascript">
    jQuery(document).ready(function(){
        jQuery('#dob').datepicker({
            dateFormat: 'dd-mm-yy'
        });
    });
    </script>
    <?php
    }
    add_action( 'register_form', 'register_jqscripts' );
    add_action('register_form','add_datepicker');

?>

simplepluginclass.php

 <label for="dob"><?php _e( 'Date of Birth', 'sportspress' ) ?><br />
               <input type="date" class="customdatepicker" id="dob" name="dob" />
          </label>

Who is "it" that is telling you something?

The link that you're referencing for jQuery is pointing to the Google Code documentation. Change the link to point to the jQuery source file on the CDN:

wp_enqueue_script('jQuery', 'https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js');

for some reason the datepicker is not loading in safari but its working now in chrome. i guess it might be a cacheing issue.
