Hi @sjl,
Thanks for the post.
For the Url return type, you can use the following code:
$home_banner = get_field('field_name', 123); // 123 is the post id that the field is listed in.
<script>window.home_banner = “<?php echo $home_banner; ?>”;</script>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class=”banner”>
<h1>Bringing nature to you <span>wherever you are</span></h1>
</div>
