Jquery 请求ashx
做了一个文章列表,要实现增删改查功能,以前常用用ajax方法中的(ajaxpro),jquery也行,那就用jquery吧,小试一下牛刀
以前做数据删除的时候都有去aspx页请求的,后来知道用ashx会更快些,以下是方法
jquery方法

function buildxml()
{
$.ajax({
type: "get",
url: "/db/AjaxHelp.ashx",
data:'buildxml=1',
beforeSend: function(XMLHttpRequest){
//ShowLoading();
},
success: function(data, textStatus){
alert('OK'); alert(data);
},
complete: function(XMLHttpRequest, textStatus){
//HideLoading();
},
error: function(){
alert('error');
}
});
{
$.ajax({
type: "get",
url: "/db/AjaxHelp.ashx",
data:'buildxml=1',
beforeSend: function(XMLHttpRequest){
//ShowLoading();
},
success: function(data, textStatus){
alert('OK'); alert(data);
},
complete: function(XMLHttpRequest, textStatus){
//HideLoading();
},
error: function(){
alert('error');
}
});
