jquery cookie需要脚本文件如下：
jquery.cookie = function(name, value, options) {if (typeof value != 'undefined') { options = options || {}; if (value === null) { value = ''; options = $.extend({}, options); 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(); } 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 { 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]); if (cookie.substring(0, name.length + 1) == (name + '=')) { cookievalue = decodeuricomponent(cookie.substring(name.length + 1)); break; } } } return cookievalue;}};
页面调用只要引进这个文件
$.cookie(name); //根据cookie名字取到cookie值$.cookie(name, value);//设置cookie 名字，值$.cookie(name, value, { expires: 7 }); //设置cookie 名字，值，生命周期等属性$.cookie(name, null); //根据cookie名移除cookie
希望本文所述对大家jquery程序设计有所帮助。
