The implementation code summary of javascript cookie operation class is attached to the usage method

The first method: the cookie operation class, the code is encapsulated, and there are also usage methods below, you can refer to it.

Copy the codeThe code is as follows:

 
 = function() 
{ 
return (/^\s+/g,"").replace(/\s+$/g,""); 
} 
function JSCookie() 
{ 
 = function(key) 
{ 
var cookie = ; 
var cookieArray = (';'); 
var getvalue = ""; 
for(var i = 0;i<;i++) 
{ 
if(cookieArray[i].Trim().substr(0,) == key) 
{ 
getvalue = cookieArray[i].Trim().substr( + 1); 
break; 
} 
} 
return getvalue; 
}; 
 = function(cookiekey,childkey) 
{ 
var child = (cookiekey); 
var childs = ('&'); 
var getvalue = ""; 
for(var i = 0;i < ;i++) 
{ 
if(childs[i].Trim().substr(0,) == childkey) 
{ 
getvalue = childs[i].Trim().substr( + 1); 
break; 
} 
} 
return getvalue; 
}; 
 = function(key,value,expire,domain,path) 
{ 
var cookie = ""; 
if(key != null && value != null) 
cookie += key + "=" + value + ";"; 
if(expire != null) 
cookie += "expires=" + () + ";"; 
if(domain != null) 
cookie += "domain=" + domain + ";"; 
if(path != null) 
cookie += "path=" + path + ";"; 
 = cookie; 
}; 
 = function(key) 
{ 
expire_time = new Date(); 
expire_time.setFullYear(expire_time.getFullYear() - 1); 
var cookie = " " + key + "=e;expires=" + expire_time + ";" 
 = cookie; 
} 
} 

usage:
1. Set cookies
var cookie = new JSCookie();
//Normal settings
cookie .SetCookie("key1","val1");
//Expiration time is one year
var expire_time = new Date();
expire_time.setFullYear(expire_time.getFullYear() + 1);
cookie .SetCookie("key2","val2",expire_time);
//Set the domain and path with expiration time
cookie .SetCookie("key3","val3",expire_time,".","/");
//Set the cookies with subkeys, and the subkeys are k1, k2, k3 respectively.
cookie .SetCookie("key4","k1=1&k2=2&k3=3");
2. Read cookies
//Simple access
cookie .GetCookie("key1");
cookie .GetCookie("key2");
cookie .GetCookie("key3");
cookie .GetCookie("key4");
//Get the value of key4's subkey k1
cookie .GetChild("key4","k1");
3. Delete
cookie .Expire("key1");
cookie .Expire("key2");
cookie .Expire("key3");
cookie .Expire("key4");
The second method: cookie operation function, I also use this. You can choose according to your needs.

Copy the codeThe code is as follows:

function setCookie(name, value) //cookies set JS
{ 
var argv = ; 
var argc = ; 
var expires = (argc > 2) ? argv[2] : null; 
if(expires!=null) 
{ 
var LargeExpDate = new Date (); 
(() + (expires*1000*3600*24)); 
} 
 = name + "=" + escape (value)+((expires == null) ? "" : ("; expires=" +())); 
} 

function getCookie(Name) //cookies read JS
{ 
var search = Name + "=" 
if( > 0) 
{ 
offset = (search) 
if(offset != -1) 
{ 
offset +=  
end = (";", offset) 
if(end == -1) end =  
return unescape((offset, end)) 
} 
else return "" 
} 
}

How to use:

Copy the codeThe code is as follows:

if(getCookie("yxjok")!="ok"){ 
//Judge whether the value of yxjok in the cookie is ok, and the following advertisement is displayed.
('<div ><a href="https://" onclick="Closeyxj()" target="_blank"><img src="https:///images/" 
/></a></div>'); 
} 
function Closeyxj(){ 
//Close the reality of advertising.  And the record of using cookies has been displayed. The main function here is that if it is not displayed for a period of time after being turned off, the default is 24 hours.
$("jb51_yxj").='none'; 
setCookie("yxjok","ok",10); 
} 

function setADCookie(name, value) // It mainly changes the expiration time of cookies to several minutes.
{ 
var argv = ; 
var argc = ; 
var expires = (argc > 2) ? argv[2] : null; 
if(expires!=null) 
{ 
var LargeExpDate = new Date (); 
(() + (expires*1000*300)); 
} 
 = name + "=" + escape (value)+((expires == null) ? "" : ("; expires=" +())); 
}
