Adding READ LESS to bottom?

I don’t get a persistent ‘read more’ link, it just disappears entirely.

I have modified the files and can get a ‘close’ link at the end, but can’t get the ‘more’ link back afterwards. Just a warning – I don’t know much about js and sort of fudged this together. Anyone got any suggestions?

Javascript file (pobo_rmi.js)

var $j = jQuery.noConflict();

$j('document').ready(function(){
	$j('.readmoreinline').hide();
	$j('.close').hide();
	$j('.more-link').click(function(e){
		e.preventDefault();
		$j(this).empty().parent().next('.readmoreinline').show();
		$j('.close').show(); 

			$j('.close').click(function(e){
	$j('.readmoreinline').hide();
	$j('.close').hide();
	});
	});

});

read-more-inline.php

function pobo_rmi_morelink_filter($link){
	global $post;
	$my_id = $post->ID;
	 //$spanId = "more-" . $post->ID;
		$post_object= get_post($my_id);
		$content = $post_object->post_content;
        // grab only the stuff after 'more'
        $debris = explode('<!--more-->', $content);

	$link.='</p><p class="readmoreinline">'.$debris[1].'</p><a class="close">close</a>';
	return $link;
}

add_filter('the_content_more_link', pobo_rmi_morelink_filter, 999);

Update: adding a blank link to the ‘close’ tag works as it will reload the page.

function pobo_rmi_morelink_filter($link){
	global $post;
	$my_id = $post->ID;
	 //$spanId = "more-" . $post->ID;
		$post_object= get_post($my_id);
		$content = $post_object->post_content;
        // grab only the stuff after 'more'
        $debris = explode('<!--more-->', $content);

	$link.='</p><p class="readmoreinline">'.$debris[1].'<a class="close" href="">(close)</a></p>';
	return $link;
}

add_filter('the_content_more_link', pobo_rmi_morelink_filter, 999);
