javascript js method

本文实例讲述了JavaScript仿静态分页实现方法。分享给大家供大家参考。具体如下：

这里基于JavaScript模仿网页不刷新静态分页的功能，实际用的时候估计要做些改动，因为目前需要分页的内容是作为一个字符串变量存在JS里，使用时这里的数据要变为数据库中读取的数据，不知道它的实用性有多高，需要的朋友慢慢调整一下。

运行效果如下图所示：

具体代码如下：

&amp;lt;HTML&gt;
&amp;lt;HEAD&gt;
&amp;lt;TITLE&gt; 静态分页&amp;lt;/TITLE&gt;
&amp;lt;style&gt;
* {
font-size:10.2pt;
font-family:tahoma;
line-height:150%;
}
.pContent
{
border:1px solid red;
background-color:#FFD2D3;
width:500px;
word-break:break-all;
margin:10px 0px 10px;
padding:10px;
}
&amp;lt;/style&gt;
&amp;lt;/HEAD&gt;
&amp;lt;BODY&gt;
header
&amp;lt;p id=&quot;pPagenation&quot;&gt;&amp;lt;/p&gt;
&amp;lt;p id=&quot;pContent&quot;&gt;&amp;lt;/p&gt;
