利用jQuery 实现GridView异步排序、分页的代码_jquery

选择

var getPageData=function(i)
{
$.ajax({
url:'Restore.aspx?'+new Date()+'&page='+i,//指定pageindex
type:'get',
success:function(data,textStatus)
{
$('#ShowData')[0].innerHTML=data;
},
error:function(XMLHttpRequest,textStatus)
{
//debugger;
$('#ShowData').text(XMLHttpRequest.responseText);
},
complete:function(XMLHttpRequest,textStatus)
{
}
});

var sortDataGridView=function(sortExpression,sortDirection)
{
event.returnVaule=false;//阻止提交服务器
$.ajax({
url:'Restore.aspx?'+new Date()+'&sortEx='+sortExpression+'&sortDir='+sortDirection,//IE从在缓存，因此加new Date（）防止缓存的影响
type:'get',
success:function(data,textStatus)
{
$('#ShowData')[0].innerHTML=data;
},
error:function(XMLHttpRequest,textStatus)
{
$('#ShowData').text(XMLHttpRequest.responseText);
},
complete:function(XMLHttpRequest,textStatus)
{
}
});
}
