/*****************************************************************************************************
Name Shopping Cart
Version 1.1
Author Vanni (Fanlin) url:www.27sea.com qq:303590170
CreateDate 2005-05-31
Description
This class is based on JavaScript and client cookies, make sure the client opens cookies
Data retention (default 24*30 hours) is available through this.expire=? Hours to specify
Typeobj and Proobj have two identical property names for both the two objects in the class: Name and Value
The data in a class is stored in the following form-----------------------------------
Array (
New Typeobj (' Auto ', array (
New Porobj (' Mitsubishi ', 200),
New Proobj (' Honda ', 500)
)
),
New Typeobj (' Egg ', array (
New Proobj (' egg ', 10),
New Proobj (' duck eggs ', 20)
)
}
The Cookie Access form is encrypted using the escape () function--------------
Shopping Cart name = car # Mitsubishi: 200| Honda: 500, Egg # Egg: 10| duck eggs: 20
Note: The problem does not occur when the client saves cookies. If you want to cycle storage, there may be some deposits, while some are not deposited
Workaround: See the following example (get the number of sales in the URL and save it in a cookie)
File: JS code fragment in/depot/compareproduct.php
<script language= "JavaScript" >
var car=new car (' compare ');
var typename= ' list ';
Car.deltype (TypeName); Clear the previously contrasted product
Get the parameters in the URL and separate the groups
var url=location.href;

var end=url.indexof (' & ');
if (end==-1) end=url.length;
var urlparam=url.substring (Url.lastindexof ('? sales= ') +7, End). Split (', ');

else{

for (i=0;i<urlparam.length;i++) {
Car.addpro (Typename,urlparam[i], ""); Add contrast product if present, return fake
}
SetTimeout (' Setpageval (); ', 100); Call itself again, not with recursion, because recursion is too fast, there will still be problems
}
