利用键盘左右键翻页效果其实只是我们利用了一款js效果,用键盘左右键实现wordpress上下翻页,其实原理和ctrl+enter来实现提交评论一样的道理,支持ie和ff,没有测试是否兼容谷歌chrome,我私下里觉得既然支持firefox那应该会支持chrome了,应该吧.</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
实例代码如下:<br>
</p>
<div style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div style="margin: 0px; padding: 0px; outline: none; float: right; line-height: 25.2px; font-size: 14px;">
<span style="line-height: 25.2px; cursor: pointer;"><u>复制代码</u></span>
</div>
代码如下:</div>
<div id="phpcode2" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
document.onkeydown = chang_page; <br>
function chang_page(e) { <br>
var e = e || event, <br>
keycode = e.which || e.keyCode; <br>
if (keycode == 37 || keycode == 33) <br>
location = "<?php echo get_permalink(get_adjacent_post(false, '42', false)); ?>"; <br>
if (keycode == 39 || keycode == 34) <br>
location = "<?php echo get_permalink(get_adjacent_post(false, '42', true)); ?>"; <br>
}</div>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>将上面给出的翻页代码复制到single.php内保存,无论是IE还是FF,均能完美实现键盘翻页,说明：get_adjacent_post()函数中的42是指排除分类ID为42的文章——也就是说,在翻页过程中会自动跳过该分类下的文章(因为本站ID=42的分类被用于改造个人微博，并不想与文章一起翻页展示),如果没有特殊要求,这个参数留空即可,读者可根据个人博客的实际需要自行修改.</span>

<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
文章列表页面(如首页、分类页面、存档页面等)是否也可以实现键盘翻页呢？我们只需使用</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
get_previous_posts_page_link()和get_next_posts_page_link()代替上述代码中的get_adjacent_post()函数即可达到目的：</p>

}</div>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>将上面的代码放置到相应页面,感兴趣的朋友可以试一下.</span>
