Usage of cookies based on jquery_jquery

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' : '');
}
