一天只弹一次的弹窗代码(javascript)

由于在blogspot中编辑的文章正文中不能有javascript代码，所以我把包含下面代码的javascript的html标签去掉了。

function setCookie(name, value, expire) {   

window.document.cookie = name + "=" + escape(value) + ((expire == null) ? "" : ("; expires=" + expire.toGMTString()));

}

function getCookie(Name) {   

   var search = Name + "=";

   if (window.document.cookie.length > 0) { // if there are any cookies

     offset = window.document.cookie.indexOf(search);

         if (offset != -1) { // if cookie exists

       offset += search.length;          // set index of beginning of value

           end = window.document.cookie.indexOf(";", offset)          // set index of end of cookie value

           if (end == -1)

             end = window.document.cookie.length;

           return unescape(window.document.cookie.substring(offset, end));

     }

   }

   return null;

}

function register(name) {

var today = new Date();

var expires = new Date();

expires.setTime(today.getTime() + 1000*60*60*24);

setCookie("SexMovie", name, expires);

}

var exitURL="http://www.jovi.cn";

function openWin() {

var c = getCookie("SexMovie");

if (c != null) {

    return;

}

register("9free");

var featureStr="''";

featureStr="'top=0,left=0,width=600,height=400,toolbar=yes, menubar=yes, scrollbars=yes, resizable=yes, location=yes, status=yes,center:yes'";

self.focus();

var ExitWindow = window.open(exitURL,'', featureStr); 

    //ExitWindow.focus(); 

}

openWin();

//window.focus()
