Source: Internet
Author: User
There's really nothing to do at the company today, suddenly thought to write down the mall shopping cart front-end framework, of course, I only have the shopping cart additions and deletions to check, perhaps write is not so perfect, but the most important is a primer, but also hope that JS talent to give some advice, so that I have a higher level.
Hoho~~~ started:
Js:
Copy Code code as follows:

In order to save trouble, did not write their own JS Ajax use of jquery, of course, you can add to the jquery extension method, haha, I am too lazy, so write here.
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) {
Unlock ();
if (xhr[0] = = "ERROR") {
Alert (xhr[1]);
Return
// }
else if (xhr[0] = = "SUCCESS") {
Jusoc.BLL.Shopping.SetData (xhr[1]);
// }
Jusoc.BLL.Shopping.SetData (XHR);
if (_successcall!= null && _successcall) {
_successcall.call (window, XHR);
}
_successcall = null;
}
function Preparerequst (Beforecall, Successcall) {
if (Islock) {
return false;
}
Lock ();
if (Beforecall!= null && beforecall) {
_beforecall = Beforecall;
}
if (Successcall!= null && successcall) {
_successcall = Successcall;
}
}
return {
Get:function (Beforecall, Successcall) {
if (Preparerequst (Beforecall, Successcall) ==false) return false;
Jusoc.DAO.Shopping.Get (_beforecall, callbackfunction);
},
Remove:function (PID, Beforecall, Successcall) {
if (Preparerequst (Beforecall, Successcall) ==false) return false;
Jusoc.DAO.Shopping.Remove (PID, _beforecall, callbackfunction);
},
Set:function (PID, Pcount, Beforecall, Successcall) {
if (Preparerequst (Beforecall, Successcall) ==false) return false;
Jusoc.DAO.Shopping.Set (PID, Pcount, Beforecall, callbackfunction);
},
Add:function (PID, Pcount, Beforecall, Successcall) {

Here to populate the data in the shopping cart
var data = Jusoc.BLL.Shopping.GetData ();
This is where you build the entire shopping cart first.
