I had trouble deleting a cookie made via JavaScript and after I added the host it worked  scroll the code below to the right to see the location host   After clearing the cookies on a domain try the following to see the results   if  document cookie length  0     document cookie    name example  expires   new Date  new Date    valueOf   1000 60 60 24 15     path    domain   location host    if  document cookie length  0   alert  Cookies disabled      else      document cookie    name example  expires Thu  01 Jan 1970 00 00 00 GMT  path    domain   location host     if  document cookie length  0   alert  Created AND deleted cookie successfully        else  alert  document cookies length     document cookies length

You can do this by setting the date of expiry to yesterday   Setting it to  -1  doesn t work  That marks a cookie as a Sessioncookie

Here is an implementation of a delete cookie function with unicode support from Mozilla   function removeItem sKey  sPath  sDomain        document cookie   encodeURIComponent sKey                           expires Thu  01 Jan 1970 00 00 00 GMT                        sDomain      domain     sDomain                             sPath      path     sPath           removeItem  cookieName      If you use AngularJs  try  cookies remove  underneath it uses a similar approach     cookies remove  cookieName

would this work    function eraseCookie name        document cookie   name       Max-Age 0      I know Max-Age causes the cookie to be a session cookie in IE when creating the cookie  Not sure how it works when deleting cookies

To delete a cookie I set it again with an empty value and expiring in 1 second  In details  I always use one of the following flavours  I tend to prefer the second one    1       function setCookie key  value  expireDays  expireHours  expireMinutes  expireSeconds            var expireDate   new Date            if  expireDays                expireDate setDate expireDate getDate     expireDays                     if  expireHours                expireDate setHours expireDate getHours     expireHours                     if  expireMinutes                expireDate setMinutes expireDate getMinutes     expireMinutes                     if  expireSeconds                expireDate setSeconds expireDate getSeconds     expireSeconds                     document cookie   key       escape value                  domain    window location hostname                 path                   expires   expireDate toUTCString               function deleteCookie name            setCookie name      null   null   null  1           Usage   setCookie  reminder    buyCoffee   null  null  20   deleteCookie  reminder      2      function setCookie params            var name              params name              value             params value              expireDays        params days              expireHours       params hours              expireMinutes     params minutes              expireSeconds     params seconds           var expireDate   new Date            if  expireDays                expireDate setDate expireDate getDate     expireDays                     if  expireHours                expireDate setHours expireDate getHours     expireHours                     if  expireMinutes                expireDate setMinutes expireDate getMinutes     expireMinutes                     if  expireSeconds                expireDate setSeconds expireDate getSeconds     expireSeconds                      document cookie   name       escape value                  domain    window location hostname                 path                   expires   expireDate toUTCString               function deleteCookie name            setCookie  name  name  value      seconds  1            Usage   setCookie  name   reminder   value   buyCoffee   minutes  20    deleteCookie  reminder
