将占位符文本添加到Wordpress wp-login.php页面

So I want to add placeholder text to the Username and Password fields on the standard wp-login.php page - I don't want to edit the actual wp-login.php page because every time WordPress is updated my amends will just be wiped.

So! In functions.php I've added a simple function to add a .js file (and some css files but I don't think that's important for this) to the wp-login.php page where I have this code - here is my function in functions.php

function my_custom_login() {
  echo '<link rel="stylesheet" type="text/css" href="/shared-assets/css/main-screen-styles.css" />';
  echo '<link rel="stylesheet" type="text/css" href="' . get_bloginfo('stylesheet_directory') . '/css/campsite-finder-screen-styles.css" />';
  echo '<script type="text/javascript" href="/shared-assets/js/test.js">
</script>';
}
add_action('login_head', 'my_custom_login');

And here is my js file

jQuery(document).ready(function(){
  jQuery('#user_login').attr('placeholder', 'Name');
  jQuery('#user_email').attr('placeholder', 'Email');
  jQuery('#user_pass').attr('placeholder', 'Password');
});

And this is where I get stuck .. in my mind that should work, I've checked the IDs and they all seem to line up but I'm clearly doing something wrong, you can see the page here http://www.camp-site-finder.com/wp-login.php

If you view the source you can see the link to my .js file and I'm referencing jQuery so errmm, have I done something stupid along the way or is there a better way of doing this?

If anyone can point me in the right direction on this one I'd be very grateful
