截图如下:
滚动鼠标中键读取Json数据分页显示网页内容，关键的Javascript如下：
<script type="text/javascript">
<!--//
function $(id){return document.getElementById(id);} //定义获取ID的方法
function GotoPage(num){ //跳转页
Page = num;
OutputHtml();
}
var PageSize = 9; //每页个数
var Page = 1; //当前页码
function OutputHtml(){
var obj = eval(siteList); //获取JSON
var sites = obj.sites;
//获取分页总数
var Pages = Math.floor((sites.length - 1) / PageSize) + 1;
if(Page < 1)Page = 1; //如果当前页码小于1
if(Page > Pages)Page = Pages; //如果当前页码大于总数
var Temp = "";
var BeginNO = (Page - 1) * PageSize + 1; //开始编号
var EndNO = Page * PageSize; //结束编号
if(EndNO > sites.length) EndNO = sites.length;
if(EndNO == 0) BeginNO = 0;
if(!(Page <= Pages)) Page = Pages;
$("total").innerHTML = "Total:<strong class='f90'>" + sites.length + "</strong> Show:<strong class='f90'>" + BeginNO + "-" + EndNO + "</strong>";
//分页
if(Page > 1 && Page !== 1){Temp ="<a href='javascript:void(0)' onclick='GotoPage(1)'><<Index</a> <a href='javascript:void(0)' onclick='GotoPage(" + (Page - 1) + ")'>Previous</a> "}else{Temp = "<<Index Previous "};
//完美的翻页列表
var PageFrontSum = 3; //当页前显示个数
var PageBackSum = 3; //当页后显示个数
var PageFront = PageFrontSum - (Page - 1);
var PageBack = PageBackSum - (Pages - Page);
if(PageFront > 0 && PageBack < 0)PageBackSum += PageFront; //前少后多，前剩余空位给后
if(PageBack > 0 && PageFront < 0)PageFrontSum += PageBack; //后少前多，后剩余空位给前
var PageFrontBegin = Page - PageFrontSum;
if(PageFrontBegin < 1)PageFrontBegin = 1;
