为什么我的javascript代码不能在functions.php中运行？

Question

I've developed a theme in wordpress and it all works fine except for the javascript. What is the problem?

This is the code in functions.php

function dstrkt_script_enqueue() 
{

    wp_enqueue_style('customstyle', get_template_directory_uri() . '/css/customstyle.css', array(), '1.0.0', 'all');
    wp_enqueue_style('normalize', get_template_directory_uri() . '/css/normalize.css', array(), '1.0.0', 'all');
    wp_enqueue_style('icons', get_template_directory_uri() . '/css/icons.css', array(), '1.0.0', 'all');
    wp_enqueue_style('demo', get_template_directory_uri() . '/css/demo.css', array(), '1.0.0', 'all');

    wp_enqueue_script('customjs' , get_template_directory_uri() . '/js/dstrkt.js', array(), '1.0.0', true);
    wp_enqueue_script('borderMenu' , get_template_directory_uri() . '/js/borderMenu.js', array(), '1.0.0', true);
    wp_enqueue_script('classie' , get_template_directory_uri() . '/js/classie.js', array(), '1.0.0', true);

}

add_action( 'wp_enqueue_scripts', 'dstrkt_script_enqueue');

function dstrkt_theme_setup() 
{

    add_theme_support('menus');

    register_nav_menu('primary', 'Primary Header Navigation');
    register_nav_menu('secondary', 'Footer Navigation');

}

add_action('init', 'dstrkt_theme_setup');
