一.封装
jQuery.cookie = function (key, value, options) { ???// key and value given, set cookie... ???if (arguments.length > 1 && (value === null || typeof value !== "object")) { ???????options = jQuery.extend({}, options); ???????if (value === null) { ???????????options.expires = -1; ???????} ???????if (typeof options.expires === ‘number‘) { ???????????var days = options.expires, t = options.expires = new Date(); ???????????t.setDate(t.getDate() + days); ???????} ???????return (document.cookie = [ ???????????encodeURIComponent(key), ‘=‘, ???????????options.raw ? String(value) : encodeURIComponent(String(value)), ???????????options.expires ? ‘; expires=‘ + options.expires.toUTCString() : ‘‘, // use expires attribute, max-age is not supported by IE ???????????options.path ? ‘; path=‘ + options.path : ‘‘, ???????????options.domain ? ‘; domain=‘ + options.domain : ‘‘, ???????????options.secure ? ‘; secure‘ : ‘‘ ???????].join(‘‘)); ???}二.调用
//存cookiejQuery.cookie("username","admin",{ expires:7 });jQuery.cookie("password","123456",{ expires:7 });//取cookievar username = $.cookie("username");expires:7设置过期时间为7天，-1为关闭浏览器后失效
三.备注
JQuery的版本为1.6.2。以上为个人笔记，可能不具备参考性。
