jquery cookie的用法

时间：2011-01-09 来源：墟零

var account= $.cookie('name');
取一个cookie(name)值给myvar

代码如下

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;
   }
};

然后看了下Discuz!中对cookie的操作方法
如下,发现少了个遍历用;分割的数组的处理

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' : '');
}
