wp_page_reload_on_back_button_js()

Outputs JS that reloads the page if the user navigated to it with the Back or Forward button.

description

Used on the Edit Post and Add New Post screens. Needed to ensure the page is not loaded from browser cache, so the post title and editor content are the last saved versions. Ideally this script should run first in the head.

源代码

File: wp-admin/includes/misc.php

	?>
	<script>
		if ( typeof performance !== 'undefined' && performance.navigation && performance.navigation.type === 2 ) {
			document.location.reload( true );
		}
	</script>
	<?php
