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。
