JavaScript仿靜態分頁實現方法
編輯：關於JavaScript
本文實例講述了JavaScript仿靜態分頁實現方法。分享給大家供大家參考。具體如下：
這裡基於JavaScript模仿網頁不刷新靜態分頁的功能，實際用的時候估計要做些改動，因為目前需要分頁的內容是作為一個字符串變量存在JS裡，使用時這裡的數據要變為數據庫中讀取的數據，不知道它的實用性有多高，需要的朋友慢慢調整一下。
運行效果如下圖所示：
具體代碼如下：
<HTML>
<HEAD>
<TITLE> 靜態分頁</TITLE>
<style>
* {
font-size:10.2pt;
font-family:tahoma;
line-height:150%;
}
.divContent
{
border:1px solid red;
background-color:#FFD2D3;
width:500px;
word-break:break-all;
margin:10px 0px 10px;
padding:10px;
}
</style>
</HEAD>
<BODY>
header
<div id="divPagenation"></div>
<div id="divContent"></div>
footer
<SCRIPT LANGUAGE="JavaScript">
