实例讲解jquery与json的结合

//下一页按钮click事件
$("#next").click(function(){
pageIndex += 1;
ChangeState(1,-1);
if(pageIndex>=pageCount)
{
pageIndex = pageCount;
ChangeState(-1,0);
}
bind(pageIndex);
});

//最后一页按钮click事件
$("#last").click(function(){
pageIndex = pageCount;
ChangeState(1,0);
bind(pageIndex);
});
});

//AJAX方法取得数据并显示到页面上
function bind()
{
$("[@id=ready]").remove();
$("#load").show();
$.ajax({
type: "get",//使用get方法访问后台
dataType: "json",//返回json格式的数据
url: "Handler.ashx",//要访问的后台地址
data: "pageIndex=" + pageIndex,//要发送的数据
complete :function(){$("#load").hide();},//AJAX请求完成时隐藏loading提示
success: function(msg){//msg为返回的数据，在这里做数据绑定
var data = msg.table;
$.each(data, function(i, n){
var row = $("#template").clone();
row.find("#OrderID").text(n.OrderID);
row.find("#CustomerID").text(n.CustomerID);
row.find("#EmployeeID").text(n.EmployeeID);
row.find("#OrderDate").text(ChangeDate(n.OrderDate));
if(n.RequiredDate !== undefined) row.find("#ShippedDate").text(ChangeDate(n.RequiredDate));
row.find("#ShippedName").text(n.ShipName);
row.find("#ShippedAddress").text(n.ShipAddress);
row.find("#ShippedCity").text(n.ShipCity);
row.find("#more").html("<a href=OrderInfo.aspx?id=" + n.OrderID + "&pageindex="+pageIndex+"> More</a>");
row.attr("id","ready");//改变绑定好数据的行的id
row.appendTo("#datas");//添加到模板的容器中
});
$("[@id=ready]").show();
SetPageInfo();
}
});
}

function ChangeDate(date)
{
return date.replace("-","/").replace("-","/");
}

//设置第几页/共几页的信息
function SetPageInfo()
{
$("#pageinfo").html(pageIndex + "/" + pageCount);
}

//AJAX方法取得分页总数
function GetPageCount()
{
$.ajax({
type: "get",
dataType: "text",
url: "Handler.ashx",
data: "getPageCount=1",
async: false,
success: function(msg){
$("#pagecount").val(msg);
}
});
}

//改变翻页按钮状态
function ChangeState(state1,state2)
{
if(state1 == 1)
{
document.getElementById("first").disabled = "";
document.getElementById("previous").disabled = "";
}
else if(state1 == 0)
{
document.getElementById("first").disabled = "disabled";
document.getElementById("previous").disabled = "disabled";
}
if(state2 == 1)
{
document.getElementById("next").disabled = "";
document.getElementById("last").disabled = "";
}
else if(state2 == 0)
{
document.getElementById("next").disabled = "disabled";
document.getElementById("last").disabled = "disabled";
}
}

3.利用JSON三方控件在服务器端获取JSON格式数据
