example $.cookie('name', 'value');
Set the value of the cookie and set the value of the name variable to value
example $.cookie('name', 'value', {expires: 7 , path: '/', domain: 'jquery.com', secure: true});
Create a new cookie including the validity period, path, domain name, etc.
example $.cookie('name', 'value');
Create a new cookie
example $.cookie('name', null);
Delete a cookie

var account= $.cookie('name');
Get a cookie( name) value to myvar

The code is as follows

Copy the codeThe code is as follows:

 
jQuery.cookie = function(name, value, options) { 
if (typeof value != 'undefined') { // name and value given, set cookie 
options = options || {}; 
if (value === null) { 
value = ''; 
options.expires = -1; 
} 
var expires = ''; 
if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) { 
var date; 
if (typeof options.expires == 'number') { 
date = new Date( ); 
date.setTime(date.getTime() (options.expires * 24 * 60 * 60 * 1000)); 
} else { 
date = options.expires; 
} 
expires = '; expires=' date.toUTCString(); // use expires attribute, max-age is not supported by IE 
} 
var path = options.path ? '; path=' options.path : ''; 
var domain = options.domain ? '; domain=' options.domain : ''; 
var secure = options.secure ? '; secure' : ''; 
document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join(''); 
} else { // only name given, get cookie 
var cookieValue = null; 
if (document.cookie && document.cookie != '') { 
var cookies = document.cookie.split(';'); 
for (var i = 0; i < cookies. length; i ) { 
var cookie = jQuery.trim(cookies[i]); 
// Does this cookie string begin with the name we want? 
if (cookie.substring(0, name. length 1) == (name '=')) { 
cookieValue = decodeURIComponent(cookie.substring(name.length 1)); 
break; 
} 
} 
} 
return cookieValue; 
} 
}; 

Then I looked at the cookie operation method in Discuz!
as follows, and found that there is missing a traversal; split array Processing

Copy code The code is as follows:

 
function getcookie(name) { 
var cookie_start = document.cookie.indexOf(name); 
var cookie_end = document.cookie.indexOf(";", cookie_start); 
return cookie_start == -1 ? '' : unescape(document.cookie.substring( cookie_start name.length 1, (cookie_end > cookie_start ? cookie_end : document.cookie.length))); 
} 
function setcookie(cookieName, cookieValue, seconds, path, domain, secure) { 
var expires = new Date(); 
expires.setTime(expires.getTime() seconds); 
document.cookie = escape(cookieName) '=' escape(cookieValue) 
 (expires ? '; expires= ' expires.toGMTString() : '') 
 (path ? '; path=' path : '/') 
 (domain ? '; domain=' domain : '') 
 (secure ? ' ; secure' : ''); 
}
