button onclick with get_post_permalink

Question

I developed a custom post type. On my archive page for each post there is a <button>. The problem is that I can't put the link to the post in question. My button is in my loop.

<button type="button" onclick="window.location.href='<?php get_post_permalink();?>'"> Click here </button>

get_post_permalink() only returns the value. You still need to echo it (and escape it for good measure):

<?php echo esc_url( get_post_permalink() );?>
