Imitation Douban paging prototype (Javascript version)_javascript skills

I haven’t posted anything for a long time~~.
Due to work needs, I wrote a paging style imitating Douban style.
I feel that this kind of paging takes into account both front and back, which is very good for the user experience.

<meta http-equiv="content-type" content="text/html; charset=gb2312"> <meta name="author" content="Smiling Dolphin"> <meta name="keywords" content="design, css, cascading, style, sheets, xhtml, graphic design, w3c, web standards, visual, display, java, javascript, c , php, jsp, asp, py, pl"> <meta name="description" content="my favorites language."> <meta name="robots" content="all"> <title>Imitation Douban paging prototype (Javascript version) </title> <style type="text/css" title="currentStyle" media="screen"> /* Paginator */ .paginator { font: 14.8px normal Arial, Helvetica, sans-serif; color: #666666; margin-top: 10px; margin-bottom: 5px; line-height: 150%; background-color: #EEFFEE; text-align: center; } .paginator a, .thispage, .break { padding: 2px 4px; } .paginator .prev { margin-right: 20px; } .paginator .next { margin-left: 20px; } .paginator .count { margin-left: 20px; font-size: 11px; } </style> <div id="pagebar" class="paginator"></div>
