WordFress插件选项页面中的JSFiddle

I made a script in jsfiddle http://jsfiddle.net/JGM85/279/ and wanted to use it in my plugin option page. I created the css file(css/style.css) and a js file(js/main.js) And I referenced it like this:

<script type="text/javascript" src="js/main.js"></script>
<link href="css/style.css" rel="stylesheet" />

But the datepicker is not working nor the js and css. Does Wordpress has a special way of calling JS,Jquery, and css files?

Updated code

function super_plugin_scripts(){
        wp_enqueue_script('jquery-ui-core');
    wp_enqueue_script('jquery-ui-datepicker');
}
add_action('wp_enqueue_scripts','super_plugin_scripts');
?>
<html>

<div class="demo">

<p>Date: <input type="text" id="datepicker" placeholder="Select a date"></p>

</div><!-- End demo -->


</html>

Try to use below code:

//SETUP
function super_plugin_install(){
        //Do some installation work
}
register_activation_hook(__FILE__,'super_plugin_install');

Add Script and Style : (Please add css and js inside your plugin folder)

//SCRIPTS
function super_plugin_scripts(){
        wp_register_style( 'my-plugincss', plugin_dir_url( __FILE__ ).'css/style.css' ) );
        wp_enqueue_style( 'my-plugincss' );
        wp_register_script('super_plugin_scriptjs',plugin_dir_url( __FILE__ ).'js/main.js');
        wp_enqueue_script('super_plugin_scriptjs');
}
add_action('wp_enqueue_scripts','super_plugin_scripts');

Another way to add datapicker in your plugin :(not CSS, for css you need to follow above code)

 wp_enqueue_script('jquery-ui-core');
 wp_enqueue_script('jquery-ui-datepicker');
