ASP. NET 3. Shopping Cart created by asp.net + cookie + javascrip

(1) first, introduce the basics of javascript cookie operations.

// Remove spaces and press ENTER
String. prototype. Trim = function ()
{
Return this. replace (/(^ \ s *) | (\ s * $)/g ,"");
}

// Set Cookie
Function setCookie (c_name, c_value, expiredays)
{
Var exdate = new Date ();
Exdate. setDate (exdate. getDate () + expiredays );

Document. cookie = c_name + "=" + escape (c_value) +
(Expiredays = null )? "": "; Expires =" + exdate. toGMTString ());
}

// Read the Cookie by name
Function getCookie (c_name)
{
If (document. cookie. length> 0)
{
Var m_car = document. cookie. split (';');
Var value =-1;
For (I = 0; I <m_car.length; I ++)
{
If (c_name.toString (). Trim () = (m_car [I]. split ('=') [0]). toString (). Trim ())
{
Value = (m_car [I]. split ('=') [1];
}

}
}
Return value;
}
