this.minDisplayPageCount = 5;
var c = $(container);
var paginationLinks = "";
if(pageCount == 1) {

} else {

}
}
if(currentPage < pageCount) {

}
paginationLinks += "</ul>";
c.html(paginationLinks);
var links = $("#page_number ul li a");
links.each(function(index) {
if(!(this.innerHTML == "上一页" || this.innerHTML == "下一页")) {
$(this).click(function(event) {
alert(links[index].innerHTML);
loadData(curTaskId,"","",parseInt(links[index].innerHTML));
pagination(pageCount, parseInt(links[index].innerHTML), container, loadData);
});
}
});
var prevPage = $("#prevpage");
var nextPage = $("#nextpage");
c.css({'visibility': 'visible'});
if(prevPage) {
prevPage.click(function(event) {
loadData(curTaskId,"","",currentPage - 1);
pagination(pageCount, currentPage - 1, container, loadData);
});
}
if(nextPage) {
nextPage.click(function(event) {
loadData(curTaskId,"","",currentPage + 1);
pagination(pageCount, currentPage + 1, container, loadData);
});
}
}
loadData为加载数据的函数，这个函数需要定义一个当前页数的参数，比如：
复制代码 代码如下:
var currentPage = 1;
loadExamList(currentPage){
//TODO
pagination(5,currentPage,$(ul),loadExamList);
};
5是总页数，1是当前页数，$(ul)是要将页码按钮存放的位置，loadExamList是点击上一页、下一页或者页码的时候调用的函数。
