新建cookie，设置时间，并读取cookie方法

  <script type="text/javascript">

 

      

       $(function(){

      

            var TIME = new Date();

      TIME.setTime(TIME.getTime() + 60*60*24*1000*7);

         var cityId;

         var cityName;

           $('.ui-lf-text,.ui-city').click(function(){    

          cityId=$(this).attr('data-cityid');

          cityName=$(this).text();

                alert(cityName);

                alert(cityId);

                document.cookie = "cityName=" + escape(cityName)+"; expires=" + TIME.toGMTString()+ "; path=/poup_movie_web";

                document.cookie = "cityId=" + escape(cityId)+"; expires=" + TIME.toGMTString()+ "; path=/poup_movie_web";

               

                alert(getCookie("cityName"));

        //遍历cookie数组，处理每个cookie对

        for(var i=0;i<arrCookie.length;i++){
