Jquery ajax无刷新翻页的实现代码

var pageSize = "10";//每页行数
var currentPage = "1";//当前页
var totalPage = "0";//总页数
var rowCount = "0";//总条数
var params="";//参数
var url="activity_list.action";//action
$(document).ready(function(){//jquery代码随着document加载完毕而加载
//分页查询
function queryForPages(){
$.ajax({
url:url,
type:'post',
dataType:'json',
data:"qo.currentPage="+currentPage+"&qo.pageSize="+pageSize+params,
success:function callbackFun(data){
//解析json
var info = eval("("+data+")");
//清空数据
clearDate();
fillTable(info);
}
});
}
//填充数据
function fillTable(info){
if(info.length>1){
totalPage = info[info.length-1].totalPage;
var tbody_content="";//不初始化字符串"",会默认"undefined"
for(var i=0 ; i<info.length-1;i++){
tbody_content +="<tr>"
+"<td data-title='序号' >"+(i+1+(currentPage-1)*pageSize)+"</td>"
+"<td data-title='标题'>"+info[i].title.substr(0,20)+"</td>"
+"<td data-title='地点'>"+info[i].address.substr(0,6)+"</td>"
+"<td data-title='已报名'>"+info[i].quota_sign+"人</td>"
+"<td data-title='类别'>"+info[i].type+"</td>"
+"<td data-title='操作'><a href='<%=request.getContextPath()%>/activity_edit.action?id="+info[i].id+"'>编辑</a></td>"
+"</tr>"
$("#t_body").html(tbody_content);
}
}else{
$("#t_head").html("");
$("#t_body").html("<div style='height: 200px;width: 700px;padding-top: 100px;' align='center'>"+info.msg+"</div>");
}
}

//清空数据
function clearDate(){
$("#t_body").html("");
}

//搜索活动
$("#searchActivity").click(function(){ queryForPages(); });
//首页
$("#firstPage").click(function(){
currentPage="1";
queryForPages();
});
//上一页
$("#previous").click(function(){
if(currentPage>1){
currentPage-- ;

}
