What part do you not understand? Whatever page you saw must have contained some examples.

Just set the expiry date in the past and the cookies will be deleted.

To create cookies, you need to set an expiry date too, e.g. 1 day, 1 week.

  if (c_start!=-1)

    { 

    c_start=c_start + c_name.length+1 

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