jquery.cookie.js代码的内容并不多,可以直接拷贝一下
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('')); } // key and possibly options given, get cookie... options = value || {}; var result, decode = options.raw ? function (s) { return s; } : decodeURIComponent; return (result = new RegExp('(?:^|; )' + encodeURIComponent(key) + '=([^;]*)').exec(document.cookie)) ? decode(result[1]) : null; };
