使用方法如下:
<div class="nav-previous"><?php next_posts_link(__( \'<span class="meta-nav">«</span> Older posts\', \'your-theme-textdomain\' )) ?></div>
<div class="nav-next"><?php previous_posts_link(__( \'Newer posts <span class="meta-nav">»</span>\', \'your-theme-textdomain\' )) ?></div>
感谢伊恩·斯图尔特的代码。
