1.用pager方法，输入参数，会返回一个导航条的html字符串。方法的内部比较简单。
ajax-pager.js
/**
* pageSize, 每页显示数
* pageIndex, 当前页数
* pageCount 总页数
* url 连接地址
* pager(10, 1, 5, ‘Index‘)使用方法示例
*/
function pager(pageSize, pageIndex, pageCount, url) {
var intPage = 5; //数字显示
var intBeginPage = 0;//开始的页数
var intEndPage = 0;//结束的页数
var intCrossPage = parseInt(intPage / 2); //显示的数字
var strPage = "<div class=‘fr‘><span class=‘pageinfo‘>第 <font color=‘#FF0000‘>" + pageIndex + "/" + pageCount + "</font> 页 每页 <font color=‘#FF0000‘>" + pageSize + "</font> 条</span>";
if (pageIndex > 1) {
strPage = strPage + "<a class=‘pageNav‘ href=‘" + url + "?pageIndex=1&pageSize=" + pageSize + "‘><span>首页</span></a> ";
strPage = strPage + "<a class=‘pageNav‘ href=‘" + url + "?pageIndex=" + (pageIndex - 1) + "&pageSize=" + pageSize + "‘><span>上一页</span></a> ";
}
if (pageCount > intPage) {//总页数大于在页面显示的页数
if (pageIndex > pageCount - intCrossPage) {//当前页数>总页数-3
intBeginPage = pageCount - intPage + 1;
intEndPage = pageCount;
}
else {
if (pageIndex <= intPage - intCrossPage) {
intBeginPage = 1;
intEndPage = intPage;
}
else {
intBeginPage = pageIndex - intCrossPage;
intEndPage = pageIndex + intCrossPage;
