JS Function to remove templates stopped working with 4.2.3

Hi,

I was using a jQuery function to remove templates from the template menu in a page edit screen. It was working well, but seems to have stopped working with the 4.2.3 update (though perhaps that’s coincidence).

Following is the function from my functions.php file. I sure would appreciate any thoughts.

/* remove most page templates to keep things simple */
function my_remove_page_template() {
    global $pagenow;
    if ( in_array( $pagenow, array( 'post-new.php', 'post.php') ) && get_post_type() == 'page' ) { ?>
        <script type="text/javascript">
            (function($){
                $(document).ready(function(){
                    $('#page_template option[value="sidebar-content-half-page.php"]').remove();
                    $('#page_template option[value="sidebar-content-page.php"]').remove();
                    $('#page_template option[value="sitemap.php"]').remove();
                    $('#page_template option[value="full-width-page.php"]').remove();
                    $('#page_template option[value="landing-page.php"]').remove();
                    $('#page_template option[value="content-sidebar-page.php"]').remove();
                    $('#page_template option[value="content-sidebar-half-page.php"]').remove();
                    $('#page_template option[value="blog.php"]').remove();
                    $('#page_template option[value="blog-excerpt.php"]').remove();
                })
            })(jQuery)
        </script>
    <?php
    }
}
add_action('admin_footer', 'my_remove_page_template', 10);

Thanks ??
