To create cookies, you need to set an expiry date too, e.g. 1 day, 1 week.
See these two links:

if (document.cookie.length>0)

  {

  c_start=document.cookie.indexOf(c_name + "=")

  if (c_start!=-1)

    { 

    c_start=c_start + c_name.length+1 

    c_end=document.cookie.indexOf(";",c_start)

    if (c_end==-1) c_end=document.cookie.length

    return unescape(document.cookie.substring(c_start,c_end))

    } 

  }

return ""

}
 
function setCookie(c_name,value,expiredays)

{

var exdate=new Date()

exdate.setDate(exdate.getDate()+expiredays)

document.cookie=c_name+ "=" +escape(value)+

((expiredays==null) ? "" : ";expires="+exdate.toGMTString())

}
 
function checkCookie()

{

username=getCookie('username')

if (username!=null && username!="")

  {alert('Welcome again '+username+'!')}

else 

  {

  username=prompt('Please enter your name:',"")
