简单的前端简单的前端js+ajax 购物车框架购物车框架(入门篇入门篇)
今天在公司实在没有事做，突然就想到写下商城的购物车的前端框架，当然我这里只有购物车的增删改查，也许写的并不是那
么完善，但最重要的是一个入门，也希望js达人给些建议，好让我更上一个台阶。
HOHO~~~开始咯：
Js：
代码如下:
//为了省事，就没写自己的js ajax了 用了jquery的，当然你也可以添加到jquery的扩展方法内,哈哈，我太懒了，所以就写这里
了。
var _$ = { AJAX: function (urlparm, d, beforecall, successcall) {
$.ajax({
url: “ashx/ajax_shoppingCart.ashx?” + urlparm,
data:d,
dataType:”Json”,
type: “POST”,
before: beforecall,
success:successcall
});
}
};
(function () {
var Jusoc = {};
Jusoc = {
_inital: function () { window.Jusoc = Jusoc; },
Base: {},
DAO: {},
BLL: {},
UI: {}
}
Jusoc.Base = {
Validate: {
}
}
//AJAX()
Jusoc.DAO = {
Shopping: {
Get: function (beforecall, successcall) {
_$.AJAX(“action=get”, null, beforecall, successcall);
},
Remove: function (pid, beforecall, successcall) {
_$.AJAX(“action=remove”, { “pid”: pid }, beforecall, successcall);
},
Add: function (pid, pcount, beforecall, successcall) {
_$.AJAX(“action=add”, { “pid”: pid, “pcount”: pcount }, beforecall, successcall);
},
Set: function (pid, pcount, beforecall, successcall) {
_$.AJAX(“action=set”, { “pid”: pid, “pcount”: pcount }, beforecall, successcall);
}
}
}
Jusoc.BLL = {
Shopping: (function () {
var Data = null;
var isLock = false;
var _successcall = null;
var _beforecall = null;
function Unlock() {
isLock = false;
}
function Lock() {
isLock = true;
if(Data&&Data !=null)
{
Data = null;
}
}
function CallBackFunction(xhr) {
