I found good code for get/set cookies:

我找到了获取/设置cookie的好代码:

function setCookie(c_name,value,exdays)
    {
      var exdate=new Date();
      exdate.setDate(exdate.getDate() + exdays);
      var c_value=escape(value) + 
        ((exdays==null) ? "" : ("; expires="+exdate.toUTCString()));
      document.cookie=c_name + "=" + c_value;
    }

    function getCookie(c_name)
    {
     var i,x,y,ARRcookies=document.cookie.split(";");
     for (i=0;i<ARRcookies.length;i++)
     {
      x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
      y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
      x=x.replace(/^\s+|\s+$/g,"");
      if (x==c_name)
      {
       return unescape(y);
      }
     }
    }

See the official MS Developer Network docs -> https://msdn.microsoft.com/en-us/library/ms533693%28v=vs.85%29.aspx

If you set no expiration date on a cookie, it expires when the browser closes. If you set an expiration date, the cookie is saved across browser sessions. If you set an expiration date in the past, the cookie is deleted. Use Greenwich Mean Time (GMT) format to specify the date.

如果您没有在cookie上设置过期日期,它将在浏览器关闭时到期。如果您设置了过期日期,则会在浏览器会话中保存Cookie。如果您过去设置了过期日期,则会删除Cookie。使用格林威治标准时间(GMT)格式指定日期。

So you basically need to specify an expiration date if you want the cookie to persist in IE. Example from the link above :

因此,如果您希望cookie在IE中持久存在,您基本上需要指定过期日期。上面的链接示例:

// Create a cookie with the specified name and value.
function SetCookie(sName, sValue)
{
  document.cookie = sName + "=" + escape(sValue);
  // Expires the cookie in one month
  var date = new Date();
  date.setMonth(date.getMonth()+1);
  document.cookie += ("; expires=" + date.toUTCString()); 
}
